Sequencer Site SIRTF IOC Activity c. 2002

CAID: MIPS-900 Title: Start-up Activities, Si
 
System: MIPS Principal: dmkelly Deputy: cengelbracht
Objective:  
Prepare the MIPS Si array for science 
operations
by
            executing a standard set of MIPS
turn-on tasks.
 
Description:
1) Turn on power to the combined electronics
   2) Transition from OFF to MIPS_OBSERVE
   3) Perform thermal anneals on the Si array
   5) Point the telescope to the first desired
target
   6) Before beginning the next IOC task, wait 
as
necessary until
      30 minutes has elapsed since the CE 
power-on
 
Day:   5.9194444444438 Suggested Order:  
 
Must be preceded by these activities (list by CAID):   MIPS-015
 
Place in Schedule:   At the start 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: Successful completion of MIPS-015


Resources

Duration:   30 minutes
 
Real time downlink:   No   

Data Volume (uncompressed): 5 Mbits
 
List Blocks, AORs, SERs, IERs, or unique sequences required (uplink): Power-on blocks, 24um thermal anneal IER
 
List Analysis tools required (downlink):   A spreadsheet for looking at the thermal diagnostic data

Outcome


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 temperature telemetry
 
 
Success criteria: The thermal anneal will be considered successful if the anneal heater turns on and off as expected and if the array temperature changes 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.
