R. Thompson (NRAO) and D. T. Emerson (NRAO) 02/04/03 Keywords: sensitivity, linear detectors, square-law detectors, half-wave, full-wave The sensitivity in the measurement of Guassian noise power using a half-wave detector can suffer degradation relative to that of a full-wave detector, in cases where the bandwidth if the input waveform is not small compared to the center frequency. There are two physical mechanisms that suggest a basis for this effect. The half-wave detector responds to only half of the input waveform, resulting in possible loss of information. Also, in the half-wave detector a component of the input spectrum feeds through the diode and adds to the noise that is subsequenctly filtered by averaging at the detector output. This feedthrough component does not occur in full-wave detectors. The phenomena are examined using an analytic method developed by Nuttall (1986), and also by numerical simulation. The results for both linear and square-law characteristics are considered, and formulas and graphs for estimating the magnitude of the effects are given.

The discussion is based on FTS measurements and model calculations of submillimeter/millimeter atmospheric emission under various weather conditions. Liquid water in the atmosphere (cloud or fog) limits the phase correction accuracy using the total power measurements. Comparison between millimeter and submillimeter total power phase correctionshows that the sensitivity requirement is more easily met at submillimeterwavelengths under good atmospheric conditions (precipitable water vapor[pwv] < 1 mm), and the phase correction error due to liquid water is muchless at these wavelengths. Simultaneous operation of millimeter and submillimeter receivers will further reduce the phase correction error appreciably.

Carolyn From cwhite at NRAO.EDU Thu Apr 11 11:04:44 2002 From: cwhite at NRAO.EDU (Carolyn White) Date: Thu, 11 Apr 2002 11:04:44 -0400 (EDT) Subject: [alma_na] ALMA NA DH Teleconference Minutes Message-ID: ALMA NA DH Teleconference - 2002-Mar-04 Attendees - Cunningham, Glendenning, Gray, Kingsley, Mangum, Perfetto, Porter, Radford, Rafal, Sramek, Webber, White, Wootten Rafal received a notification that there will be an AMAC meeting the last half of June 2002 in Europe. Rafal stated the requirements will be done on a case by case basis. Typically the IPT leaders will be required to attend. We do not have an agenda as of yet. At the AUI trustees sub-committee meeting on ALMA they discussed the overall planning for going into construction. There is a strong recommendation that the US go ahead with its funding profile; not to wait for European funding. Sramek requested the NA/European funding profile viewgraph that Rafal presented at the NA DH face-to-face meeting. Status Reports -------------- Gray - Gray agreed to descope the original documentation system that was presented by Tan and Oliver. We only need to control specific areas. And each sub-system will be able to determine how to do there own documentation. Each IPT will be expected to supply the Project with its hardware; Gray expects to have a draft within the a week or two. The system engineering group has reviewed Site-Scape for the Project; Oliver is setting up a test bed at the moment. We will use the current project book as the first test. Gray is also setting up an ICD list with all sub-systems. The design reviews process will also be overhauled; Sramek has agreed to use the new process for the Back End PDR at ALMA week. New documents will be added for the design review. We continued to discuss the new ideas Gray had for the project book. Most users felt we should have an overall collection of specifications. Webber - The foundry has started to work on the custom chips and we expect to receive them in April. The lab started integrated tests on the multiplier cards. We revised the current boards to accommodate the voltage changes, etc., and expect to send them to the foundry in late summer. The design of the active correlator rack is underway; metric tooling and hardware has been ordered. Porter - Customs office called and stated that the review of our denial for duty free status will probably be overturned. This will reduce the costs for the prototype antennas. Kingsley - We have finally resolved the software errors on the surface panels. The panels are coming along now. All plant integration is going along quite well. The BEI encoders are finished and the final testing will be done at the end of the week. Kingsley met with Vertex last week to discuss how the NRAO can integrate our components with the prototype antenna. Vertex has stated the complete, accepted prototype antenna will be ready on July 29, 2002. We still need to get the information for the European and Japanese foundation. Perfetto - We are in the assembly mode for the holography receiver; will be ready for test next week. We are still waiting for parts for the shields. The second frame for the receiver is complete. Radford - Mechanical parts for the nutator is in production. The material and parts are on order for the subreflector molds. Site development is going well. We are moving forward with the site characterization issues. We have full access to instruments via satellite phones which have now been fixed. Sramek - Sramek needs to know when Webber needs the 3-bit digitizer at 4 GHz. Webber stated there is no hurry; we do not need it until March/April 2003. The interface specifications are written down. We experienced problems installing the ball grids on the array devices on the daughter cards. A company in Albuquerque will attempt to do this for us. The holography tower has been installed. Glendenning - Marson and Pokorny officially took over Brooks' responsibilities on March 1st. Brooks will be at the NRAO offices until July 2002. The next control software release will be completed this week. Sramek and Glendenning will look at rack space for central computers. ALMA week is finalized. Baars has sent out an updated agenda. Our next meeting will be Monday, March 11, 2002. -------------------------------------------------------------------- ALMA NA DH Teleconference - 2002-Mar-11 Attendees: Brown, Cunningham, Glendenning, Gray, Kingsley, Mangum, Payne, Radford, Rafal, Simon, Sramek, White, Wootten Rafal received comments on the schedule and he and Simon will incorporate them into a new version. Rafal will contact each person within the next couple of days on staffing positions in the next year. Rafal stated that the antenna testing will be done in only single dish mode with total power deferring interferometer testing until pre-production back end components are available. This has lots of benefits for the back end system. Rafal has already discussed this with numerous persons involved. Mangum confirms this and states that he cannot see a reason that we need spectroscopy to evaluate the prototype antennas. Sramek will still produce the down converter, 2nd LO, the LO reference receiver, and all the first IF equipment for the antenna testing, as well as the M/C monitors. We will discontinue the up-rate converter, downconverter and we would re-direct the data for the ALMA prototype version. This also simplifies what the Japanese would need for their prototype antenna; they would supply their own receiver which would meet specifications. We would then not use their antenna for interferometer testing. Due to the delays in delivery of the prototype antennas our interferometer testing time frame has been significantly reduced anyway. Rafal will be discussing these issues with the ALG before the ASAC meeting. It will then be taken to the AEC and we expect to have final approval within the next couple of weeks. Simon discussed the travel budget. Each sub-system has a management account where Simon will move all travel monies too. Everyone agreed this was more appropriate. Training is to be charged to a specific work element. Relocation is a overhead item. Simon will be sending out a list of approved overhead items. Status Reports -------------- Sramek - We found a commercial vender to place the ball grid chips on boards. We are also looking at purchasing equipment to possibly place chips on the boards in-house. The vendors will be contracting for our larger production needs. Peereboom is sending prototype integrated board to Summers for cleaning, etc. We are waiting for the cards for the data transmission system; expect to have layout for fabrication within the next couple of weeks. It has been concluded that Sramek is responsible for integration. Kingsley believes we should re-circulate Mangum's cabling plan to verify all sub-systems; Kingsley will then get this into the contract. We should continue the interferometer cabling as planned. Glendenning - There was a control software release last week. We ordered the VME crates today. Kemball reported on the IRAM test on AIPS++. Raffi and Glendenning are finalizing skeleton plan in Grenada. Marson and Pokorny are taking over Brooks' responsibilities. Kingsley confirms that the antenna bus master will be in the control cabin rack. Sramek - Rack drawings will be presented at the Back End PDR. The racks are not completely full. Kingsley stated that Alcatel's receiver cabin will not fit our equipment racks. Kingsley - We are pushing Alcatel for their foundation details; however, we do not know when we will get the drawings. The transporter concept design should be ready by ALMA week. Alcatel has provided April 18, 2003 as their current delivery date. The Vertex panels are meeting specifications and they are working on a production schedule. All machining has been completed on the invar cone. Hexapod has been received and accepted by Vertex. The encoders have been tested and are being shipped to Vertex in Santa Clara. The panels at ESO look good, but Kingsley cannot discuss this in any further detail. Radford - Site development planning has been updated. Brown, Radford, and Hardy will meet with Hofstadt in Santiago April 8, 2002. Gray and Radford will visit M3 to discuss current road plans in Chile. Payne - The OMT is being cold checked in Australia. Initial results on the thru-arm look good; we expect test results this week. The 1 mm OMT drawings are complete. At the Photonics meeting last week, we discussed commercial line spectra that is available for correction. The prototype cone generator has been developed in Australia and will be tested in Tucson the first week of April. The block diagrams need to be changed. Working on agenda for ALMA Week. Cunningham - The band 3 SIS devices have been fabricated by UVA and seem to be fine; two will be available next month. The evaluation receiver and holography are proceeding well. While in Charlottesville, I was able to review band 6. A mixer meeting will be arranged. Brown - The AEC has agreed to the site planning changes. There will be an ALMA Bi-lateral Teleconference March 25, 2002. ------------------------------------------------------------------------ ALMA NA DH Teleconference - 2002-Apr-01 Attendees - Mangum, Radford, Brown, Simon, Gray, White, Glendenning, Sramek, Kingsley, Webber, Porter, Perfetto Brown asks for any open issues for the ALMA Week planning. Brown questions Porter on the import issues. Porter stated that we had heard the duty free status was going to be reversed. This has been received by the NSF. A outside report found that most of the federal procurements have been done by sole source procurements; we may see changes in these policies. Justifications may be required to be expanded and scrutinized more. Kingsley - Near term milestones include getting the antenna on site and working at the site. One of the top concerns we face is making sure our material is working. Receiver interface plate working and electrical connections. The cabling plan needs to be completed. Sramek has de-scoped the plans for the ATF and hopes to be able to assign technical staff for the cabling issues. Optical pointing telescope has been signed off to the computing group. The nutator should be delivered in late July, including the computer interface. The nutator is being added to the Product Tree. Rafal and Kingsley discussed staffing positions for the antenna sub-system. Perfetto - Holography going well; receiver is wired up completely. Brooks is working on the firmware. We are approximately 6 - 8 weeks behind schedule. Delivery on sis mixers is well. We are working on the second receiver frame. Waiting for a few major components for the second receiver. Photonics Shillue is putting together the test site - hardware format, etc. The holography transmitter is ready and waiting for photomixer; software control issues are not completed. Holography testing at the ATF is to begin in October; radiometric test are to begin in January 2003. Mangum - Ortela is integrating weather devices. We received the final three hardware pieces to be working on the weather instruments; two laptops and the cabling. Sramek - Holography tower is up and contractor is doing final work on it; retensioning guide cables, etc. We are asking engineers for a letter stating the minor detail changes that will not be a safety hazard. the delivery f the trailer is on order, but it is being delayed. We cannot put it in place before it is inspected. The trailer will be installed near the end of April. The cable pull to that site will be done in a couple of weeks. The back end subsystem is preparing the re-defining task. We got the second channel working. It has a complex bit pattern; goes at 100 Gbytes/second over cabling; we will now bring in the fiber optic board. Testing will be done in May. We are devoting most of our time to the Back End PDR to be held during ALMA Week. Webber - Most engineers were attending a meeting last week. The chief concern during these meetings was: i) who is doing all the IF amplifiers; ii) the availability of transitters. To test the transitter situation we will need to do another wafer run. More work will be done to figure out how to get a handle on this. The Japanese statement "the test cryostat with no load takes 10 hours to cool down" causes the CDL concerns. The local oscillator purchase rec has been signed by Webber and is being processed. Webber will be prepared to speak to this during ALMA Week; including numbers, etc. The prototype correlator chip is due May 15. The engineers are designing and check out of the rack design, etc., are on-going. Glendenning - Working on tasks related to the next software release. Integration issues are being worked on. Working on material for the Granada meeting. Each work element responsible person is writing documentation on their area. Requisitions are waiting for HR in Charlottesville to continue their processes; White will work with HR today on this. Gray - Oliver is setting up the documentation system and working on server issues. Gray sent out memo on user names, etc. Oliver gave a sample presentation to the Tucson group on the documentation system. Working on the product tree for the ALMA Project that Tan had originated; this is quite urgent to work out. Simon ask if the AEC has formally agreed on the new standards for design reviews. Gray answered no; this is being discussed. Sramek would like to see some more details worked out. Radford - Negotiations with Hofstadt with agenda at meeting in Santiago to discuss distribution of task and scheduling in Chile. Have started M3 engineering doing comparisons on road locations; the choice of that road will determine the site of the OSF. Kingsley asked M3 to redo the estimate of foundation cost in Chile; expect to have this by end of the week. Brown reports that we have received two installments of monies from NSF. The ASAC met for two days and the Japanese spoke for one day. The scientist reviewed the proposal process. The future correlator design in Europe was discussed last week at the meeting the CDL personnel attended. Switching design was discussed; Webber and Sramek will look into this off-line. The Japanese are finding the Project harder to sell now in Japan with the way they will be required to join the Project. The ACC is intent on signing the ALMA agreement in June 2002 of this year; Japan will not be ready to sign at this time. Simon - Phase 2 accounts are active and should be used. Phase 1 accounts will be closed down soon. We don't want to burden our accounts any further with leftover Phase 1 tasks. New accounts will be added to the Phase 2 system to account for Phase 1 non-completed tasks. Sramek asks about the fiscal reports that have been requested for a long time; Porter states he is working on getting reports for DH going back to the beginning of this fiscal year (FY2002). Our next meeting will be April 8 at 1700 UT. ------------------------------------------------------------------------ ALMA NA DH Teleconference Minutes - 2002-Apr-08 Attendees: Avery, Glendenning, Sramek, Perfetto, Payne, Kingsley, Radford, Rafal, Webber, Porter, Simon Marc brought the group up-to-date with the ACC meeting planning. anticipated that the ACC will approve the basic planning documents form the AEC and carry those forward to their funding agencies to be approved this summer. One area that is of concern is the planning for how to do the antenna procurement. The NA is proposing a process that puts in place an option to make a decision point in Spring 2003 if the Vertex antenna proves to meet the specifications and Vertex agrees to a price in the cost envelope, the Project could decide to go with Vertex without waiting for the Alcatel antenna, however we do not have to exercise this option. The decision date is a controlled date. Kingsley - Expect Vertex to arrive in late April early May. Early in June we should be able to have a communications date. Moving antenna in late June; expect to have a complete antenna in late July. Optical pointing telescope and nutator are in the planning process and moving along well. Several other options are in process and we expect to complete them soon as well. Nutator coding issues are being worked on by outside contractors. The nutator control interface ICD should be issued soon. NRAO will be responsible for the cabling at the ATF. After review we realized the cost savings were very little. Long and Chavez will lead the cabling effort; we expect to have outfitting done by June 1. All of this work is predicated on descoping the AEG testing plan. Perfetto - The evaluation receiver assembly is underway, but is taking longer than expected. We plan to cool cartridges for the first time in two weeks. Some of the components for the second evaluation receiver are complete. Some of the ports for the evaluation receiver are being programmed now. The holography is our first priority. The transmitter has been built and tested; it works ok. We are waiting for the photomixers to return from RAL. The feeds, transmitter, holography reference are being set to Georgia Tech for measurement. Carter is doing additional measurements on the main holography ??. The holography wiring is complete; we are almost ready for the M&C integration. Glendennign reports that the software has been implemented. Lucas is still working on several issues. Lucas will come to Socorro for installation and training. Testing can be done in the lab with a transmitter and receiver. The system integration of the holography will probably be done on the antennas. Sramek will deliver the de-scope IF down converter without the second IF strap or the second total power. We are still planning on providing the LO reference via photonics. The line length connector is not needed immediately. There is a significant descoping for the Back End. The test correlator may be needed by the EVLA; it should not be dismantled. Mangum - The laser interferometer has been delayed from the company. We are trying to install the solar filter. The weather instrumentation is is ready to install on towers; we are waiting for the ethernet installation. The trailer is expected to arrive on May 1. The computing sub-system will have the task of integrating all the bits and pieces. Rafal - Rafal noted the need for a coordinated schedule for antenna activities. Rafal requested that everyone send him the deliverables and dates. Mangum questioned a to get to the ALMA Test Site from the AOC; the Project may need to increase the cars at the AOC. Mangum also pointed out their may be a significant lead time to receive GSA cars. We also need to be concerned about the availability of food at the site. Sramek stated food service at the site should be available at end of May; however this is costly ($400/day for 10 persons). The next meeting will be April 15 at 1700 UT. From soliver at NRAO.EDU Fri Apr 12 16:12:42 2002 From: soliver at NRAO.EDU (Stacy Oliver) Date: Fri, 12 Apr 2002 13:12:42 -0700 Subject: [alma_na] [almanews] ALMA Memos 419 Released Message-ID: ALMA MEMO #419 THE Y+ LONG-BASELINE CONFIGURATION TO ACHIEVE HIGH RESOLUTION WITH ALMA Angel Ot?rola (ESO) & Mark A. Holdaway (NRAO) 04/12/2002 Keywords: Y+, configuration, resolution, roads, pads The ALMA array configuration design has been split into a compact array, an extended array, and a ?zoom? spiral array which aims to connect them. The currently accepted extended array is a 14 km ring around Chasc?n. Based on Fourier plane coverage, resolution, operations, engineering, and environmental arguments, we present an alternative to the extended configuration: a Y-shaped set of zooming configurations, which naturaly grows out of the spiral zoom configurations. This set of preliminary configurations indicates a savings of about 20 km in roads and cables, and 35 fewer pads compared to the current ring design. It has smoothly varying resolution, which permits the observer to tailor the resolution to his requirements. Reconfiguration is much smoother with the Y configuration than the 14 km diameter ring. The most extended Y configuration obtains the same resolution as the 14 km ring array. However, in order to achieve these advantages, together with the highest possible resolution for the ALMA interferometer, we need to explore the possibility of extending the Science Preserve by at least two kilometres to the west of its current western boundary.

Wolfgang has accepted a position with SRON to work on the HIFI space instrument. Although it would be impossible for him in his new position to devote the time and attention necessary for the ALMA Frontend Leader job, he will continue to manage the NOVA work on Band 9 for ALMA. As most of you know, Wolfgang with Charles Cunningham has been actively organizing the frontend activities for the upcoming ALMA week. Wolfgang will definitely continue that function. We plan to advertise for a new ALMA European Frontend Team Leader immediately. In the interim until the new Team Leader is selected, Gie Han Tan at ESO will serve as European Frontend Team Leader while continuing as System Engineering Team Leader. I'm sure you all join me in expressing great appreciation to Wolfgang for the hard work he has put into the ALMA frontend and wishing him the best in his new position.
