PI: Mr. Thomas Wheeler Space Telescope Science Institute Y CoI: Dr. Alan D. Welty Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract This proposal is designed to permit a safe and orderly recovery of the NUV-MAMA detector after an anomalous shutdown. This is accomplished by using slower-than-normal MCP high-voltage ramp-ups and diagnostics. Anomalous shutdowns can occur because of bright object violations, which trigger the Global Hardware Monitor or the Global Software Monitor. Anomalous shutdowns can also occur because of MAMA hardware anomalies or failures. The cause of the shutdown should be thoroughly investigated and understood prior to recovery. Twenty-four hour wait intervals are required after each test for MCP gas desorption and data analysis. Event flag 2 is used to prevent inadvertent MAMA usage. The recovery procedure consists of four separate tests (i.e. visits) to check the MAMA’s health after an anomalous shutdown: signal processing electronics check, slow, intermediate voltage high-voltage ramp-up, ramp-up to full operating voltage, and fold analysis test (See COS TIR 2010-01). Each must be successfully completed before proceeding onto the next. This proposal executes the same steps as Cycle 18 proposal 12430. ------------------------------------------------------------------------------------ Observations Description ------------------------ Anomalous shutdowns can occur because of bright object violations, which trigger the Global Hardware Monitor or the Global Software Monitor. Anomalous shutdowns can also occur because of MAMA hardware anomalies or failures. The cause of the shutdown should be thoroughly investigated and understood prior to recovery. Twenty-four hour wait intervals are required after each test for MCP gas desorption and data analysis. Event flags are used to prevent inadvertent MAMA usage. The recovery procedure consists of four separate tests (i.e. visits) to check the MAMA’s health after an anomalous shutdown. Each must be successfully completed before proceeding onto the next. This proposal executes the same steps as Cycle 18 proposal 12430. (1) Signal processing electronics check. The amplifier threshold voltage is reduced from 0.48V to 0.28V; ORCOUNTS rates are monitored (MAMA HV is off during this procedure). (2) Slow, intermediate voltage high-voltage ramp-up. The MCP HV is slow-ramped to a voltage 300V below nominal. A dark time-tag exposure is taken during this partial ramp. A second dark time-tag exposure is taken where the event counter 12724( 3) - 20-Jun-2012 13:52:58 - [ 2] is cycled through W, X, Y, Z, OR, EV and VE. (3) Ramp-up to full operating voltage. As before, a dark time-tag exposure is taken during this ramp-up. A second dark time-tag exposure is taken where the event counter is cycled through W, X, Y, Z, OR, EV and VE. (4) Fold analysis test (See COS TIR 2010-01). In order for a recovery to be initiated the following conditions have to have been met: (1) MAMA HV shut down anomalously. (2) A minimum of 24 hours must have elapsed since the initial shutdown and the intermediate HV ramp-up (step two above). (3) The COS external shutter must be closed. 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. ------------------------------------------------------------------------------------ 12724( 3) - 20-Jun-2012 13:52:58 - [ 3] Visit: 01 Visit Requirements: GYRO MODE 3GOBAD; ON HOLD ; PARALLEL On Hold Comments: To be used only after an anomalous shutdown of the NUV high voltage.

The FAT will be conducted during a deuterium lamp time-tag exposure. The exposure specification will ensure that the FCA aperture will be used, that the OSMs will be positioned at NCM1FLAT and G185M/1850, and that the lamp current is set to MEDIUM. Qesiparm TARGTYPE must be specified as FOLD so that the instructions will command the proper FAT lamp. Note that the FAT commanding will turn the lamp off during the exposure, and the exposure commanding will issue a redundant lamp off command after the exposure.
