It is shown that a system with an ambient load, a hot (100 Celsius or so) load, and a semi-transparent grid with 50 % transmission allows to reach a 1 % accuracy on the receiver gain even in presence of saturation. The best precision requires a device which offers the 5 major combinations: Sky, Sky+Ambient, Sky+Hot, Ambient, Hot. If saturation is negligible, the system can be used as a standard dual load calibration device, with better accuracy.

It is found that it may be better to observe the calibrator at the same frequency as the target, since suitable calibration sources may be just as close at higher frequencies as they are at 90 GHz (all roughly 1? for continuum bandwidths). In the end it will depend on the characteristics of the sources (size, mostly). Observing the calibrator at 90 GHz will require an additional calibration to be performed on fairly short timescales (of order minutes) to calibrate the relative complex gain between the target and calibrator frequency, since the electronics will change between scans. This extra calibration is not required if calibrator and target are observed at the same frequency. In addition, observing the calibrator at the same frequency as the target removes the requirement of having very accurate atmospheric modelling in order to transfer the phase and amplitude from calibrator frequency to target frequency (especially problematic in regions of dispersion near strong telluric lines). Because of the uncertainty in the sizes of the sources, it is not recommended to change the current paradigm of calibrating at 90 GHz, but the option of calibrating at the target frequency should be kept in mind, and exercised if it turns out that the sources considered herein are appropriate to use as calibrators (small enough).

Saini 2003-01-01 Keywords: Frequency Multiplier, Planar Integrated Frequency Multiplier, Doubler, Tripler, MMIC, Integrated Capacitor, Integrated Spiral Inductor, Amplitude Noise, Phase Noise, Noise Transmission Matrix This ALMA memo, also published as a dissertation at the University of Virginia in January 2003 (UVA Science & Engineering Library call number Diss. Engr. 2003.S24), presents a novel GaAs on Quartz based approach toward larger band-width Schottky diode frequency multipliers and reports the first fully integrable frequency multiplier based on this composite substrate is reported. This technology was developed as a low cost solution for meeting the ALMA frequency multiplier requirement up to about 400 GHz. This technology has since then been commercially applied to design and build frequency triplers for the first local oscillator chains for ALMA bands 6 and 7. The memo also describes other contemporary state-of-the-art frequency multiplier technologies and provides a comprehensive up to date survey of existing frequency multiplier designs together with their measured performances from published literature.

Previously, the full text of the reports was sent by email to all subscribers. It was provided as plain ASCII in the body of the email, not as an attachment and not encoded in HTML or any other language. The resulting emails were relatively short, and the text was immediately accessible to the recipient. For awhile, the text was being supplied only via a link into ALMAEDM. (Not a direct link, but one of the very long strings that is actually a command to a program running in ALMAEDM; thus, the actual location of the file is not contained in the link.) Even then, the file itself was not plain ASCII but rather a word processor file or PDF file. More recently, the reports have sometimes been distributed as attachements to email. Simpler is better, and far more effective. The reports are intrinsically just plain text, and there is no need to "process" them into fancy fonts. They should be maintained in ASCII (.txt) files, and distributed in the body of emails to those who wish to subscribe. Another problem is the consolidation of the two lists (mmawkprog and mmawkrpt) into one. Under the previous system, nearly everyone working on the project would get an automated request for a report every Thursday by using one of these lists, and then the compiled reports would be distributed the following Monday to the other list. That was a good arrangement because it enabled people to subscribe even though they are not contributors, and it enables those who are solicited as contributors to unsubscribe if they don't want to read about everybody else's work each week. The "request" list should be maintained by the management, but the "distribution" list should allow individuals to subscribe or unsubscribe as they wish. An improvement to the previous system would be to send the report requests on Friday, not Thursday. Often, by the time the week is over and a report might be written, the request has been forgotten. --Larry ===================================================================== Larry R.

Kemball, K. Golap, G. Moellenbrock (NRAO) R. Lucas, D. Broguiere (IRAM) 2003-09-10 Keywords: Software, Off-line, Science, Calibration, Imaging This report describes the results of testing to assess the ability of AIPS++ to be adapted to the needs of the ALMA reduction software. Specifically: 1) how can AIPS++ be adapted to reduce data of an instrument for which it was not designed, 2) how long is the learning curve for developers who have sufficient experience in the processing of millimeter data, but no experience at all of the AIPS++ programming environment, and 3) can we perform an end-to-end experiment on actual, real-life millimeter-wave spectroscopic data?

It has been divided into three parts: Phase I Implementation of PdBI (Plateau de Bure Interferometer) calibration engines inside AIPS++; Phase II Test of the calibration extensions implemented in Phase I and of the native AIPS++ capabilities (in particular, imaging capabilities) on a fair sample of PdBI data sets by a panel of testers outside the AIPS++ team; Phase III Benchmarking of AIPS++ on ALMA-size data sets using the calibration extensions implemented in Phase I. This report addresses every aspect linked to Phase II. Section 2 details the findings on the test charge as seen from Phase II. Section 3 is a collection of recommendations to the AIPS++ project. These findings and recommendations follow naturally from the experience gained during Phase II, which is summarized in Appendix A. In all sections of this appendix, the text gives only the mean of a response sample whose dispersion is sometimes large. We thus encourage the reader to go through all the questionnaires available in Appendices B through H, to obtain an idea of the full range of feedback.
