Switched to series mode about 6 hours ago. Cooling continued including
power leads until LHe level at about 50% and powerleads appeared stable. |

Hi there,
This is Khashayar (experimenter). Lookin at all different temperatures and

Tue Jun 13 15:52:46 2006, Willy Andersson, Quench Recovery, Doug has reduced and now closed CV155.
|
Now in full // cold return mode.
Had just talked with Curtis, He said thta he has already informed the
experimentors that the solenoid will not be ready until tommorow, so he

Wed Jul 28 21:26:19 2004, Doug Preddy, Quench Recovery, Double Power bump
|
Two power bumps tonight. Everything tripped of. Restarted cooling water
pump, diff. pump under solenoid etc. Computer stayed on! Starting
compressor. |

Sun Oct 17 05:03:13 2004, Other, Start Up, Cycle valve after oscillations begin
|
(Sat night/Sun AM) Helium temperature started oscillating, so
powered off magnet (precautionary) and cycled valve 142 (at 04:12).
Small oscillations begin almost immediately, so close and open

|
Due to curent lead temperature occilation Doug recommended warming up the
current leads.

Fri Jul 21 07:39:37 2006, Doug Preddy, Quench Recovery, Cool down continues
|
| Raised PIC229 to 11Bar. Started to close HIC155. Cooling rates improve. |

Fri Jun 25 12:36:04 2004, Willy Andersson, Quench Recovery, Compressor unloaded etc.
|
At about 09:30 this morning I noticed the sound coming from the compressor
building seemed louder than usual. After entering the building I noted that
the compressor was unloaded to about 50% and the compressor suction was

Sat Aug 7 22:37:04 2004, Willy Andersson, Quench Recovery, Compressor tripped off.
|
Got a call at about 10:00 this morning, the whole system had tripped off.
No power bumps or other disturbances. When I arrived the only fault
indications were "ColdBox Trip" light on the compressor panel and on the

Tue Jun 13 10:54:27 2006, Doug Preddy, Quench Recovery, Compressor tripped off
|
No indicator lights etc as to why the compressor tripped. The only light
was a cold box fault. I had to shut off the main breaker before the
compressor would come back on.

Wed Nov 15 11:09:28 2006, Doug Preddy, Quench Recovery, Compressor tripped off
|
Compressor tripped this morning at ~8:45. I restarted the compressor, but
turbine 1 would not spin up. I let it warm for an hour and it started. I
started flow to the solenoind in parallel cold return. |
|
Thu Oct 12 11:53:04 2006, Willy Andersson, Quench Recovery, Compressor trip, 09:50 this morning.
|
Main compressor tripped, refrigerator shutdown. Checked with experimentors
and main control room, no indications of power bump etc.
|
|
Mon Jul 18 15:51:17 2005, Doug Preddy, Quench Recovery, Compressor restarted, flow to solenoid
|
Recovered the vacuum in the solenoid, then started the compressor.
Started flow to solenoid in parallel warm return. |
|
Mon Aug 6 08:41:31 2007, Doug Preddy, Quench Recovery, Cold box trip at 6:00
|
compressor off due to cold box trip at 6:00 this morning. Restarted system
and started flow to solenoid in parallel cold return. |

Fri Apr 16 10:15:26 2004, Doug Preddy, Start Up, Changes to M9sol Vacuum PC
|
Yesterday and today there have been a number of changes made to the M9
Vacuum control computer. The computer now automatically boots up to the
Epics control page. This logbook is also automatically started. |

|
PIC 229 was down to 10.8 bar this morning. PIC 229 was trying to open CV211
to charge the system. I realized that in restoring the control to CV211 I
did not get the wire into the connector properly. Went back up to the
