TIDE Operations History - 2006

038/2006 02/07/06 19:00 - HV shutdown for Polar trim.
041/2006 02/10/06 20:35-21:24 - HV ramped to radiation belt levels after Polar trim. Ramp completed from stored command table at 01:23 on 02/11.
106/2006 04/16/06 08:45 - Problem with mirror shutdown and TIDE science telemetry. TIDE's HV was shut off, the instrument reset, patches re-loaded, and HV ramped to radiation belt levels on 04/18, 13:32-15:11. Ramp completed from stored command table at 16:03.
108/2006 04/18/06 20:11 - Polar GTM upset. Satellite reset at 07:43 on 04/19. TIDE came back up after the reset with no problems.
237/2006 08/25/06 Radiation Belt L-Shell Cutoffs changed from 6.0 (np-eq) to 6.0 (eq-sp) and 7.5 (sp-eq) to 6.5 (eq-np) to 6.5 (np-eq) to 6.5 (eq-sp) and 7.5 (sp-eq) to 6.5 (eq-np).
271/2006 09/28/06 Start MCP voltage was ramped from -2600V to -3400V at 21:42 to 21:55 and left there until 23:03 when the voltage was returned to -2600V. A significant increase in the TOF ion count rates was seen.
279/2006 10/06/06 10:35 - Changed the Start MCP voltage from -2600V to -3400V. Started reporting H+, O+, and He+ in addition to Stops.
310/2006 11/06/06 11:45 - HV shutdown for Polar spin axis adjustment.
317/2006 11/13/06 16:13-17:07 - HV ramped to radiation belt levels after Polar maneuver. Ramp completed from stored command table at 17:25.
355/2006 12/21/06 Beginning at 05:45, the start MCP voltage changed from -3400V to -3000V.
363/2006 12/29/06 Starting with radiation belt commands at 13:18 UT on 12/29/06, TIDE mirrors shutdown and never came back up. Prior to the shutdown, starting at ~09:00 UT, the mirrors stepped down due to high counts. The high voltage was turned off at 14:02 on 01/03/07. TIDE was reset, software patches were loaded, and the high voltage ramped to radiation belt levels from 16:02-17:10 on 01/04/07. The ramp was completed from stored commands at 18:40.
