The TUDA @ ISAC-II grounding test was successfully completed this am
per work permit 2011-04-12-2.

We measured 60V/0mA (with PSU) and 0.385MOhm with a Digital multimeter.

The TUDA grounding test is now complete. The TUDA ground breaker switch
is now closed and locked. The lockout key has been returned to ISAC Ops.

      FTS RS44LT Set Low (SL) parameter changed from -43 deg C to +5 deg C

15.00 Test of coolant loop in air - no gross leaks

15.30 Commence pump down to test coolant loop at vacuum

See attachment 1 - time from turbo ON to 5.0E-5Torr ~18m

FTS RS44 switched on ~25' before datum - set point +5.5 deg C
      TUDA.PNG5 pressure continues to decrease - coolant loop appears
      to be OK

16.55 FTS RS44 temp +5.8 deg C
