PI: Mr. Thomas P. Wheeler Space Telescope Science Institute CoI: Dr. Alan D. Welty Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract This proposal is designed to permit recovery of the SBC (FUV MAMA) detector after an anomalous shutdown. Anomalous shutdowns can occur as a result of bright object violations which trigger the Bright Scene Detection or Software Global Monitor. Anomalous shutdowns can also occur as a result of SBC hardware problems. The recovery from anomalous shutdown procedure consists of four tests: a signal processing electronics check, a slow high voltage ramp-up to an intermediate voltage, a slow high-voltage ramp-up to the full operating voltage, and lastly, a Fold Test. During the two high-voltage ramp-ups, dark ACCUM exposures are taken. At high voltage, dark ACCUM exposures and diagnostics are taken. This proposal is based on proposal 11884, visits 1 to 4. ------------------------------------------------------------------------------------ Observations Description ------------------------ The SBC (a FUV MAMA detector) Recovery from Anomalous Shutdown consists of four tests (i.e. visits) where each must be successfully completed before the next. The visits are enabled for execution by the clearance of flag 2. The visits are: (1) Signal processing electronics check. This reduces amplifier thresholds to 0.28V and monitors the ORCOUNT rates. (MAMA HV is off during this procedure.) (2) Intermediate high voltage ramp-up. The MAMA is ramped to an MCP voltage 300V below the nominal operating value. A dark ACCUM is taken during this partial ramp-up. Then a dark ACCUM is taken while W, X, Y, Z, OR, EV and VE counters are sampled. (3) Full high voltage ramp-up. The MAMA is ramped to the nominal MCP voltage. A dark ACCUM is taken during this full ramp-up. Then a dark ACCUM is taken during which events counter is cycled through W, X, Y, Z, OR, EV, and VE counters are sampled. (4) Fold analysis test. The fold analysis provides a measurement of the distribution of charge cloud sizes incident upon the anode giving some measure of changes in the pulse height distribution of the MCP and, therefore, MCP gain. This is accomplished by disabling/enabling different combinations of decoder rows and columns. For the Anomalous Shutdown tests to be executed, the following conditions have to have been met: For visit 01: There was an anomalous MAMA HV shut down and the reason for the shutdown is understood. For this and visits 02 and 03, the ACS M3 fold mirror must be in the HRC position and the Cal Door must be in the Deployed position; 12393( 7) - 13-Apr-2011 17:04:00 - [ 2] For visit 02: A minimum of 24 hours must have elapsed since the initial shutdown prior to beginning the intermediate HV ramp-up. For visits 02, 03, 24 hours are required for telemetry and data analysis. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- This is not a requirement but it is desirable to have real-time engineering telemetry (MA return) during the execution of the first three visits. ------------------------------------------------------------------------------------ 12393( 7) - 13-Apr-2011 17:04:00 - [ 3] Visit: 01 Visit Requirements: GYRO MODE 3GOBAD; ON HOLD ; PARALLEL On Hold Comments: To be used only after an anomalous shutdown of the SBC high voltage.

Since no high voltage is involved, this visit may be scheduled within the 24 hour period following an anomalous HV shutdown. There are no images taken in this visit, only telemetry is required.
