The nature of the shutdown, i.e., over-light, HV current transient ("crackle"), ion feedback (induced by a high energy particle), or field emission (possibly caused by dust or other particulate on the QE grid or other close-by structure or hardware), and the value of the commanded HV at the time of the shutdown will determine what visits are executed. Because of gain sag and the selected Lifetime Position, commanded HV settings updates may be required. First, prior to execution of this proposal or selected visits from this proposal, all preliminary steps should be exercised to gather the necessary diagnostic data, e.g., science data evaluation (if a science exposure was in progress and the science data is available), memory dumps (DCE, EXEC RAM, and possibly the CS BUFFER), engineering telemetry, or other information that might provide insight as to the nature of the shutdown and estimated count rate. The complete step-by-step procedure is detailed in the Observing Description, but in summary, the following is done: Day 01 activities, visits 01-07, contain both QE grid off and on HV ramping to HVLow (100/100) with diagnostics (DCE dumps) and darks to exclude QE grid involvement in the shutdown. Subsequent to day 01, all HV ramping will be with the QE grid on with the same diagnostics and exposures. All days end with the setting of COS event flag 3 to prevent any FUV HV commanding. Time is allotted for COS instrument scientist and engineers to examine data dumps, science exposures, and engineering telemetry. If all is well, the go-ahead will be given to clear flag 3 for the next day's visits. This proposal is modeled after the Cycle 32, Proposal 17621. ------------------------------------------------------------------------------------ 17938( 2) - 06-Jun-2025 13:26:00 - [ 2] Observations Description ------------------------ This proposal consists of necessary steps for turning on and ramping up the COS FUV high voltage in a conservative manner after an anomalous shutdown. It is intended to be used for the on-orbit turn-on of the detector after such a shutdown. Prior to execution of this proposal or selected visits from this proposal, all preliminary steps to collect diagnostic data should be exercised. 1. Gather the needed data - Do DCE dump as soon as possible 2. Circular buffer with 10 s of events and histograms of currents and voltages - Dump EXEC RAM for CVT (Current Value Table) telemetry and error logs - Examine exposure (if any) occurring during the anomaly 3. If instrument not suspended, normal readout of exposure in CS BUFFER should occur - CS BUFFER memory dump as may be appropriate - Examine engineering telemetry (including snapshots) 4. If event is determined to be similar to a previous event that did not damage the detector, and there does not appear to be evidence for more extended damage, we may decide on an accelerated recovery, e.g., - Will first go to HVLOW both without and then with the QE grid on - If HVLOW data look normal, will consider proceeding directly to HVNOM and QE grid on - Under some circumstances (i.e., a well understood event with essentially no risk of damage), we may consider returning directly to operations without additional testing 5. If event shows new or poorly understood behavior, will consult with appropriate experts prior to deciding which visits in the anomalous recovery proposal are required. 6. Primary criteria for deciding if event is the "same" as the 30 April event will be the temporal and spatial structure of the counts and gain - Sudden drop in gain followed by extended field emission - Primary emission localized to regions previously seen to have slightly enhanced dark rate - May have less information than before if shutdown occurs outside a time-tag exposure 7. Event will also be compared to FUSE like "crackles" that produced current transients 8. Shutdowns due to external or internal lamp over-light will be evaluated based on estimated level of violation to decide if damage is a concern The sequence day, visits numbers, exposures, and rough "after by" times (end to start) are listed. Number listed in parentheses, e.g., (100/100), or 154/151 are the HV command counts for Segment A and B, respectively. Throughout the proposal, different "after by" times, sequence containers, and new alignments are used to optimize flow, schedulability, telemetry and science data analyses, and the clearing of flag 3. When "after by" times are listed as 0.0 to 1.0 hr., this means that this step should be scheduled and executed as soon as possible after the previous visit. If scheduling determines that a 17938( 2) - 06-Jun-2025 13:26:00 - [ 3] longer time is required for the sequence to schedule properly, then scheduling has the right to adjust this time as they deem appropriate. The proposal is designed such that the selected visits and exposures MUST be executed in order. The proposal is designed such that the selected visits and exposures MUST be executed in order. Additionally, all visits are compliant with CARD 3.4.12.8 - COS FUV Mandatory Dwell Time at HVLow (1 hour dwell at HVLow before ramping to a more negative voltage) and CARD 3.4.12.9 -- COS FUV High Voltage QE Grid Operation (HV must be less negative or equal to the HVLow to switch grid on or off). All dark exposures will be 3600 sec. with STIMS set to 30. All wave exposures will be 60 sec. with STIMs set to 2000. Day 1 V01 Uninhibit the DCE - Flag 3 must be clear to execute. 1.

Set flag 3 17938( 2) - 06-Jun-2025 13:26:00 - [ 5] Day 07 Clear flag 3 (Real-time) - After V16 1D for analysis. Flag 3 must be clear to continue science operations. -------- Realtime Justification -------- Real-time commanding is required to clear NSSC-1 COS event flag 3 prior to visit 01 and to go ahead with the selected visits. Flag 3 must also be cleared to go ahead with science observations after the last selected visit. --------- Additional Comments ---------- This is a recovery from a HV anomalous shutdown. No regular or calibration FUV science exposures are allowed during recovery. This is not a requirement but it is desirable to have real-time engineering telemetry (MA return) during the execution of this proposal. A contingency Operations Request to place to command the FUV detector into its Inhibit mode must be in place in case a significant anomaly occurs. ISQL is required to Id S/C exposures as COS, to set the SI interleave flag properly, to adjust SI states on DUMP and HOME alignments, and to model readouts for the DCE dump exposures . See visits/exposures for detail. This proposal requires Special Commanding. ------------------------------------------------------------------------------------ 17938( 2) - 06-Jun-2025 13:26:00 - [ 6] Visit: 01 (Uninhibit DCE) Visit Requirements: ON HOLD ; PARALLEL On Hold Comments: To be used only after an anomalous shutdown of the FUV high voltage. Additional Comments: Uninhibit the DCE This visit uninhibits the DCE (sets dce_FUVInhibitMode == FALSE and does other CS cleanup, thus ensuring the DCE is in its nominal Boot state), takes diagnostics (DCE RAM dump), and transitions the FUV detector from Boot to Operate. Special commanding is used to uninhibit the DCE and to dump the DCE RAM. Regular recon commanding is used for the Boot to Operate transition. Prior to the beginning of this visit, Flag 3 must be cleared by the ground via real-time commanding. This can be done as soon as the anomalous HV shutdown is understood an the go-ahead is given to proceed with the recovery.

Several other houskeeping tasks are also cleaned up. It is assumed that this will be the first FUV activity on an SMS and that the CS is in Operate state. Therefore, the starting FUV state is set to HVLOW, which is the nominal SMS boundary state.

From Jason McPhate (Berkeley FUV detector expert, who defined the FUV initial turn-on procedure): "[I'm after] the procedure to get a memory dump of the FUV HV and AUX power current monitors (HVIA, HVIB, AUXI). Each of these has a 1000 (possibly 1024) sample buffer that monitors the current at 1ms sampling (looping through, overwriting the data that is 1 second old), and a cumulative histogram of the current values (this would be a buffer of 256 values for each monitor)."
