General Happenings

Chile        Contracting for the foundation package of the AOS building is under way.  The 
              Design Development drawings and specifications (85% complete) for the antenna 
              stations at the AOS, prepared by M3, are being reviewed.

TUC          Construction of the RF Simulator is continuing.  Despite reports in The Point 
              Source, Simon Radford still works in Tucson.  However,
              relocation of four front end IPT staff from Tucson to the NTC is largely complete.

NAASC        Planning for this facility proceed.

NTC          The assembly of the first prototype cryostat was completed one week ago in the U. K.
              modified B6(1.3mm) mixers (to improve sideband rejection) have been installed in 
              the cartridge assembly and will be tested next week.  The physical infrastructure 
              of the North American Front End integration center is close to complete.

AOC          The BE IPT is proceeding with the re-design of the TP digitizer to
              address new requirements given at the CDR:-design to accommodate 100% efficiency, 
              boxcar integration, and faster readout requested during BE IPT CDR.  Change requests
              approved include:
              o Change Cold Multiplier Ratio in Band 9 from X5 to X6 (ALMA-40.10.04.00-001-ACRE)
	      o Request to extend upper frequency limit on band 7 (ALMA-40.02.07.00-003-A-CRE)
              o Inclusion of 90d phase switching in the ALMA first LO (ALMA-56.00.00.00-001-ACRE)

******************************* TECHNICAL NEWS *******************************
Simulations of the Effects of 1/f Gain Fluctuations on Measuring Linear Polarization
with Linear Feeds on ALMA by M. A. Holdaway (NRAO)
Abstract:  Through polarization imaging simulations in aips++ which do not include 
instrumental polarization leakage of phase errors, we determine that 1/f gain fluctuations
of magnitude 1e-3 in 300s will not prevent us from obtaining the fractional polarization
specification of 0.001 for images of intermediate complexity.  In very complicated objects,
we expect there will be a limitation on the fractional polarization of weaker pixels.
