Magellan engineering meetings

March 18, 2005 11 AM Pacific time

Agenda

Intervention observing testing
Laser cutter status
March instrument engineering (see below)
A-task review
Next meeting

Instrument engineering detail

MIKE

full well and linearity issues, try the other output amp on the MIKE blue camera.

LDSS3

full well, spurious charge, noise, etc. Adjust the parallel clocks and try non-MPP operation
VPH-red grism throughput as a function of field angle (the previous observations were taken without hte OG-590 order blocking filter)
med-blue grism throughput measurements
crosstalk
horizontal charge transfer efficiency on amp 2
analyze and fix shutter problem (if it exists)

GUIDERS

do SKY and SUB commands work with Shack-Hartmann?
do cameras work OK with TEC set to 2.5?

IMACS (All of this work will take place in the CCD lab in the support building. We would like the dewar to be warmed up in time to start working on it on March 24.)

replace one of the cryotiger cooling heads in the dewar.
try and get the second wing chip to function properly
shim the CCD array in the dewar, the goal is to move the array 0.5-mm closer to the front of the dewar.
