| Title: | MIPS Detector Aliveness Check | |||||||||
| Objective: | Determine that the MIPS detectors are alive and responsive. | |||||||||
| Description: | 1) Power on MIPS detector modules. | |||||||||
| including flow / state diagram | 2) Monitor voltages to check for nominal operation. | |||||||||
| 3) Place scan mirror into dark position for each array and take 10 3-second integrations. | ||||||||||
| Send all 24um readouts to ground using "raw" mode. | ||||||||||
| Place in Schedule: | After aperture door is opened. | |||||||||
| (relative to water shed events) | ||||||||||
| Required Conditions: | None. | |||||||||
| Resources: | ||||||||||
| duration (best estimate) | 1 hr | |||||||||
| real time downlink (Y / N) | Y | |||||||||
| special post event actions (Y / N) | N | |||||||||
| Outcome: | ||||||||||
| description | Confirmation that detectors turn-on. | |||||||||
| can proceed in parallel with other activity | Yes | |||||||||
| must outcome be confirmed before next event / test /activity | Yes | |||||||||
| method of confirmation (sensor TLM, data analysis, etc.) | Mainly sensor TLM as detectors may be saturated due to high | |||||||||
| levels of scattered background light. | ||||||||||
| The "readout-only" pixels in the 160um array will be | ||||||||||
| very useful in this test. | ||||||||||
| estimate of data turn around if required for confirmation | 12 hrs. | |||||||||
| Generates 30 DCEs | ||||||||||
| Unique or included in planned AOT? | Unique. | |||||||||
| Contingency Plan: | ||||||||||
| "What if..." | If detectors cannot be powered up and found to be alive, serious fault checking of the MIPS will be required. | |||||||||
