HRC SOT Shift Report M9638

HRC Personnel: Dan Patnaude, Ralph Kraft, Gerrit Schellenberger, Tom Gauron

PLAN:
----

Execute CAP 1798

NOTES/ISSUES/PROBLEMS:
----------------------

CAP executed nominally

CLD Files used:

2A_I_DEFAULTS135.CLD
2A_DEADMAN60_200.CLD
2A_ANTICO_ON_135.CLD

SUMMARY:
------

- 60 minute deadman timer activated at 16:46z
- HRC brought to operational voltage at 17:31z

- The HRC was raised to operational levels in a controlled manner. Upon reaching
  operational levels, the team observed rates ~ 300 c/s, which are expected for
  this source. Source was observed for approximately 7 ks.
