[mmaimcal] ImCal Meeting WEDS 22 Feb

[Al Wootten]

Folks,

Recall that collisions of our usual time with a PSI meeting and with the
ASAC telecon have prompted us to move our meeting to tomorrow, which some of us
will remember as Washington's REAL birthday.

Date: 22 February 2006
Time: 4:00 pm EST (6:00 pm Santiago; 2:00 pm Socorro, 2:00 pm Tucson)
Phone: Phone: (434)296-7082 (CV SoundStation Premier Conference phone 3rd floor). No Video planned.

          o AI #18 from your report of the July 2005 SRR says:18 OPEN Sci, SE -> FE DS 2006-02-17 70 "Check need for requirement on -3dB freqs.
          o QUESTION: How big a frequency change of ANY of the local oscillators will we ever want, where we want to refer the interferometric phase of the new frequency to that of the original frequency? An equivalent question is how big a frequency change will we ever want, without having to recalibrate the phase?
                + Should our spec be "we want the phase to be reproducible within 0.5 degrees (??) for any frequency change of any LO, but we want the phase change to be computable without further calibration, to the same tolerance, for any frequency change up to [X] GHz."

Please think about the Question up for discussion.  Peter, Dick and Clint may
join the discussion.

Clear skies,
Al
