                        BIWEEKLY CALENDAR OF THE ALMA PROJECT at NRAO
                                June 21 - July 5, 2004

******************************** THIS BIWEEK ***********************************
Larry D'Addario reports that on 18 June 'in Tucson we managed to phase lock one of 
 the First LO Driver assemblies to a complete LO reference system, including a
 photonically-transmitted high frequency reference at 85 GHz...This does represent 
 an important milestone because it means that quite a bit of hardware and software is
 installed, integrated together, and working.'  Congratulations!
---------------------------------------------------------------------------
The ALMA Board meets in Munich.  Among the items to be discussed are the results of
 evaluations of prototype antenna performance and production antenna technical bids, 
 Japanese entry into ALMA and the report of the ALMA Science Advisory Committee.
---------------------------------------------------------------------------
Jennifer Neighbours arrives in CV to work at the NTC.  Welcome!

General Happenings

Chile        Folks attending a budget and schedule meeting in Santiago visited the Operations
              Support Facility (OSF) and stayed there.  See photo of OSF at www.alma.nrao.edu

ATF          The Technical Evaluation Group considering production antenna design bids has 
              submitted a report.

TUC          See LO news above.

NAASC        Paul vanden Bout has assumed duties as NAASC Head. 

NTC          All 1.3mm band (B6) cartridge components, with a lone exception, were trial fitted
	      successfully. June 16th NTC staff will attended a review prior to the initial 
	      production run of 32 cold IF amplifiersamplifiers. 
	      An agreement with JPL has been reached that gives NRAO access to sufficient 
	      numbers of devices to complete all band 6 IF amplifiers. 
	     The CCB (Change Control Board) approved the Change Request for inclusion of 
	      the Tunable Filter Bank into the Baseline Correlator.  Reviews will be scheduled.

AOC          A series of design reviews on power supplies, rack wiring, and hardware led by
              the System Architect has resulted in some changes to production plans. The changes 
              to the prototypes are minimized so that delivery of prototype equipment can 
              be completed in July. Two engineers from Bordeaux have upgraded the first Digitizers 
              delivered to Socorro; they have replaced the first generation demux chips by 
              the second generation chips (Phobos) and the sampler sub-assemblies by the 
              FIB Antares chips.   
             ALMA/AOC Computing group moved offices.  Steve Harrington has joined the group,
              working on ALMA Common Software.  Andy Hale has also joined the group, working as
              an SSR Test Assistant.

****************************** UPCOMING EVENTS ******************************
#ALMA Calendar  

    * 22-23 June -- ALMA Board Meeting, Garching
    * 8-10 July -- Software IPT CDR 2, Denver, Colorado.
    * 24 September -- ALMA/EU Meeting, Garching
    * 11-12 Oct -- AMAC Meeting, Florence, Italy

******************************* TECHNICAL NEWS *******************************
Two conference papers were submitted on the ALMA 1st LO Reference System:
Microwave Photonics 2004 Paper: Transmission of Low Phase Noise, Low Phase Drift
Millimeter-Wavelength References by a Stabilized Fiber Distribution System-PDF
SPIE Conference on Astronomical Telescopes and Instrumentation, June 2004: A High-
Coherence, High Stability Laser for the Photonic Local Oscillator Distribution of ALMA

ALMA MEMO # 501  Estimation of ALMA Data Rate R. Lucas (IRAM), J. Richer (MRAO), D. 
Shepherd (NRAO), L. Testi (Osservatorio Astrofisico di Arcetri), M. Wright (BIMA), 
C. Wilson (McMaster University)

In order to assess more firmly the estimated data rates on which The ALMA Computing 
IPT has based the design of software and hardware, the SSR has calculated the data rate 
for a sample of programmes in the DRSP prepared by the ALMA Science IPT. Due to the 
limitations in the process, the results are lower limits to the required data
rates, which are compatible with the present ALMA specifications.

Please send information for upcoming calendars by Friday evening of the
preceding biweekly period to Janet Bauer or Al Wootten via e-mail 
(jbauer at nrao.edu or awootten at nrao.edu).

The calendar will be issued between late Friday and sometime on Monday by e-mail
to all NRAO scientific staff members and anyone else interested. A specific
mailing list, alma-info, has been created for anyone wishing to receive it.  Past issues
