CAID: MIPS-990 | Title: Shut-down Activities, Si only | |
System: MIPS | Principal: dmkelly | Deputy: cengelbracht |
Objective: | Perform a standard set of MIPS tasks before turning off the instrument. |
Description: | 1) Take a short exposure 2) Perform thermal anneals on the 24um array 3) Pause 2m to allow the array to settle 3) Take a short exposure 4) Transition from MIPS_OBSERVE to OFF 5) Turn off power to the combined electronics |
Day: 6.00277777778683 | Suggested Order: | ||
Must be preceded by these activities (list by CAID): MIPS-900 | |||
Place in Schedule: At the end of each IOC campaign in which Si but not Ge measurements are planned | |||
Priority: Necessary | |||
Conditions | |||
Maximum telescope temperature: | 300 K | ||
Minimum telescope temperature: | 5.5 K | ||
Should activity be repeated if focus changes? | No Repeat if focus changes by 0 mm | ||
Maximum absolute pointing uncertainty: | 3600 arcsec (1 sigma radial) | ||
Maximum precision offset uncertainty: | 3600 arcsec (1 sigma radial) | ||
Observatory configuration: | standard | ||
Go/No Go criteria: | Succesful completion of MIPS-015 | ||
Duration: 12 minutes
| Real time downlink:
 
No | |
Data Volume (uncompressed): 17 Mbits | |||
List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): Power-off blocks, 24um thermal anneal IER | |||
List Analysis tools required (downlink): A spreadsheet for looking at the thermal diagnostic data | |||
Estimate of data turn around: 24 hours | |||
Description: The thermal anneal temperatures will be plotted and examined | |||
Can proceed in parallel with other activity: No | |||
Must outcome be confirmed before next activity: No | |||
Method of Confirmation: Visual inspection of the data and of the temperature telemetry | |||
Success criteria: The thermal anneals will be considered successful if the anneal heaters turn on and off as expected and if the array temperatures change as expected based on ground-based testing. | |||
Contingency plan: If the anneal heater fails to operate, we will need to switch to using bias boost or photon flood anneals. | |||
