MMA Costing Exercise - Wootten
Last week we discussed the second generation 183 GHz phase correction system.
Bob has a Gantt chart which has us designing this by next Jan with 
prototype and demonstration by 2001/2002 Jan.  I don't know where we
could test this but I need to come up with a cost.  My plan is to assume
a single channel (cooled?) HFET with the 32 channel backend Harris is
building.  Do Simon or Min know how much this might cost.  I'll get a
backend cost estimate from Harris if I can.  Maybe Webber can estimate
how much a contract to assemble an army of these would be.  I'll try to
get from Douglas Bock or Jack Welch a cost for the two channel amplitude
cal, then guesstimate a contract cost for 36 of those.  We need estimates of
manpower needs during construction.  Presumably there will be some ImCal
work going on at the prototype antenna, and also imaging studies, phase 
correction algorithm studies, etc.

Action Items 8Mar99

UPCOMING REVIEW: On or before 31 May 1999 we review results from the OVRO
and BIMA phase correction systems.

DECISION: 183 GHz or 22 GHz phase correction?

DECISION: Is a nutating secondary necessary?

DECISION: What is the effect of 1/f noise in the HEMT amplifiers of SIS
receivers upon our ability to combine total power and interferometric images
into a faithful representation of the sky?

MEETINGS: MAC meeting 14 Apr 1999 at noon. ------
