Operations / Software Comments - 11/10/04 TIDE Telecon

Operations:
----------

For no apparent reason, TIDE high voltage turned off at 08:53 UT on 11/09/04. 
The turn off occured during a very quiet period about 1.5 hours after perigee.
TIDE's high voltage was scheduled to be turned off for a Polar spacecraft trim
on 11/09.  During the scheduled shutdown, HV was turned off and the instrument
reset.  Software patches will be loaded and the high voltage ramped during the
17:20-21:10 DSN NRT pass on 11/13/04.

Several more tests were run to see about increasing the gain on the Stops MCPs.
Ramps were run from -1600 to -1800v on 10/13/04, -1600 to -1900v on 10/19, 
-1800 to -2000v and -1800 to -2100v on 10/26, and -1600 to -2100v on 10/29.
Some plots are available at http://satyr.msfc.nasa.gov/tideteam/gain_change/.

The Stops MCP voltage was changed from -1600 to -1800v for routine operations on
10/21/04.  To make sure that the change did not cause problems in the radiation
belts the south pole to equator radiation belt l-shell cut-off was changed from
7.0 to 7.5 on 10/21.

There is only enough disk space left on the goewin data archive for data through
the end of November.  If the new archive is not in place by then, the remainder
of the 1996 data will be temporarily removed from the GSFC web site.  The 1996 
data will be available on the NSSTC site.

To increase the amount of data displayed on a perigee plot, the times for the 
perigee plots were modified to start the plots just before the end of the 
radiation belt pass and end three hours later.  All the 2004 perigee plots were 
re-done using the new times.  This gets rid of the radiation belt data on the 
left side of the plot and gives more data on the right side of the plot.
