April 14: Test Effect when ACS Held in Dolly/Square
Configuration:
- Mounting: ACS in Handling Dolly in Square Orientation
- Cooling: Chillers
- Optical Source: HRC: Coronagraph
- Starting Temp: Ambient, at start of day
Results:
- Square Orientation has radiator heat pipes parallel to floor, and thus allows them to operate; square is also the most heat-transfer-effective for the CCD heat pipes
- Turn on HRC CCD and TECs only: ~0.5 pixel motion caused during warm-up
- Turn on chillers: no apparent change in warm-up motion trend
- Turn on WFC CCDs and TECs: causes small slope increase in warm-up trend
- Turning off chillers changed the direction of the motion trend
