Summary of M2 mini engineering run at Hanford (Dec 14, 2002)

[6-hour run: 6:00 p.m - 12:00 am. PST]

H1 behaved well, going into common mode and science running consistently.
But H2 did not cooperate at all.
Added new calibration lines nearer to unity gain point. Tested calibration line tracking and alarming.

Defined DMT viewer xml files for H1 and H2 similar to that set up for L1 in the M1 mini-run. Saved for posterity. Sample 1. Sample 2.
Various DMT bugs reported or suggestions made for improvement.
Audible DMT alarms tested (on Szabi's laptop!)
Improved visibility of stalled DMT processes on DMT workstations
SenseMonitor giving stable, calibration-line corrected ranges, but absolute scale seemed off
Two new DMT monitors exercised: SpectrumArchiver and SuspensionMon

Scientists present signed up to update eleven scimon procedure worksheets. Six were updated by the end of the run, with the others started and promised to be completed in the near future. Checklist.

On the whole, the mini-run proved useful in defining LHO-specific figures of merit, shaking down scimon procedures, and DMT code testing.
As was seen in M1, holding mini-runs in the midst of commissioning does run the risk of having an interferometer that is far from stable.
Calibration line injection and use of calibration info by DMT monitors went more smoothly than in M1.
In better shape for E9 (and more important, for S2) than we would have been without M1 and M2, but still not a smoothly oiled operation on hardware or software side.
