Calibration--Butler, Mangum
The AAS is meeting in Albuquerque in June. Some plans for the new ALMA
backdrop are at stuff.
Issues: Calibration Group Set Up
More on the photonic calibration: Comments by Larry.
3)Comments? Discussion?
3)3-1) How stable?
3)3-2) Over how long?
Recent Memos:
2) evaluate the dual load system on the Vertex antenna and the semi-transparent vane on the A/C/E antenna (or both on both). In my view neither of
these systems is ready for production. Both have been tried in the past and abandoned for reasons we think a little engineering could solve. But we need
some commitment from the FE group, already overstressed by the need for a receiver(s)... Because of the interaction between front ends, antenna and
the calibration system I think we need at least one receiver at the ATF ready to test when evaluation finishes on 1 Jan 2004. (I think it should be a
prototype band in an RAL dewar with Carter's system but...) Some major questions remain--for instance do we need two loads for the semi-transparent
system? Can we measure coupling of the dual load system well enough? Enumerating these is an action item in itself.
See Memo 372, also JGM is working on revision of his memo.
