TIDE Operations History - 1997

046/1997 02/15/97 20:47 Recover from uncommanded reset. Did a reset, a reload of all patches to this point, and a HV ramp.
049/1997 02/18/97 16:38 Abbreviated pulser test run. Table 1-10 only.
081/1997 03/22/97 FOT turned PSI off via _poff procedure; no PI team interaction. Solo for FC team for turning PSI off.
084/1997 03/25/97 First use of _ign2.prc for PSI ignition. Heater is turned off then keeper set to level 2.
101/1997 04/11/97 19:59:58 STID_HVMOFF. TIDE high voltage off for spin flip.
105/1997 04/15/97 22:17 Loaded patch to run autosensitivity from stops only rather than stops and start converts.
105/1997 04/15/97 22:30 Began TIDE post spin flip high voltage ramp.
134/1997 05/14/97 Ran PSI with EFI in low impedance mode. Don Thompson suggested run.
149/1997 05/29/97 Started PSI continuous run for 13 days, 24 hours a day. Mode is to run 2 weeks on, 8 weeks off. First use of _ign3.prc for ignition.
183/1997 07/02/97 18:00 Changed mass table to tidmtfltcal1. Changed H+ defn to go from 0 to 31 (moved lower limit from 8 to 0). (These mass changes put TIDE back in configuration prior to Feb reset.) Changed threshold 0 from 10 to 20 cts/sample. Changed priority to 4 0 3 (stops,H+,O+). Changed reporting to fixed ions 4,0,3 (stops,O+,H+). Disabled Sector 0 direct events reporting(to save TM space).
206/1997 07/25/97 First run through the radiation belt with setback voltages on the mcps at 1200 V. Mirror had to be open via opt_a_s_ena command.
225/1997 08/13/97 13:27 Started 2nd PSI continuous 14 day run. Took 3 trys and change of procedure. Problem is apparently 5 sec wait in _ign3.prc.
239/1997 08/27/97 13:10(?) PSI off
286/1997 10/13/97 15:03:46 STID_HVMOFF. TIDE high voltage turned off for semi-annual spin flip.
290/1997 10/17/97 TIDE high voltage ramped up.
309/1997 11/05/97 13:32:24(?) Started 3rd continuous run of PSI. Took 2 attempts. Keeper current was lowest ever on startup ² 300 mA, while keeper voltage was about 40 V. Wait in proc is 19 seconds. Used hard wait on second try.
310/1997 11/06/97 15:00 Large geophysical disturbance. Mirrors to lowest setting and stayed there to 311 about 15:00 UT. No gnd ops during this time.
322/1997 11/18/97 21:02:21 PSI off.
324/1997 11/20/97 01:15 Uncommanded reset on TIDE 20:36:46 STID_HVMOFF issued to TIDE. High voltages changed from armed to safe.
328/1997 11/24/97 16:45- Recovery operations and high voltage ramp. TIDE back online by 19:45. Sweep table is with sensitivity level of 7. Correct sweep table to load in first radiation belt pass.
344/1997 12/10/97 STOP MCP voltages back to 1242 V.Since the 11/20/97 reset it has been 1233 V.
