Mon Jul 18 11:18:40 2005, Doug Preddy, Quench Recovery, Solenoid Quenched over the weekend
|
The solenoid was found to be warm on Monday morning. M9Q3 had a bad water
leak over the weekend. The water header serving Q3 was turned off and the
leak confirmed. Q3 was isolated and the header was turned back on. My

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. |
|
Tue Jul 19 16:13:32 2005, Willy Andersson, Quench Recovery, switch to series mode
|
CR_6KS_M down to 11 K.
Switched to series mode.
Started small flow to power leads to get them cold.

|
Machine trip just as I was exiting the TRIUMF gate. QRL said cold box fault
as did red lite on compressor. At cold box panel all turbine red lites were
on and compressed air failure lite was on. But there was no problems with

|
| Keep IT safe boys |
|
Thu Nov 3 06:19:50 2005, Doug Preddy, Quench Recovery, restart system
|
Last night at about 7:00 there was a large power bump that shut the
compressor and water pump off. I came in this morning and am restarting the
system. |

Thu Nov 3 09:27:16 2005, Doug Preddy, Quench Recovery, started flow to solenoid
|
| started flow to solenoid in parallel cold return. |
|
Mon Dec 12 09:24:29 2005, Doug Preddy, Quench Recovery, Solenoid Quench on power lead temp
|
The solenoid tripped on power lead temps at about 9:15. I am recovering it
from it's all around mode into parallel cold return. |
|
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.

|
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 Jun 14 10:35:30 2006, Willy Andersson, Quench Recovery, Switched to series cooling.
|
Had system in //return cooling overnight with small flow to keep power
leads cool. Switched to series mode about 30 minutes ago. Building LHe
level. |
|
Wed Jun 14 16:27:01 2006, Willy Andersson, Quench Recovery, Energized solenoid
|
| Powerleads appear stable. |
|
Mon Jul 3 23:01:34 2006, Doug Preddy, Quench Recovery, power lead warming/ripples caused quench
|
power lead warming/ripples caused quench at 18:45 today. Compressor stayed
on, but flow to solenoid stopped.
I started flow to solenoid at 22:40. |
|
Thu Jul 20 00:25:16 2006, Doug Preddy, Quench Recovery, Solenoid quenched @ 11:15
|
Solenoid Quenched on C1 temp. It went above 5K. Shut off compressor.
Restarting system @ 12:15 |
|
Thu Jul 20 00:52:13 2006, Doug Preddy, Quench Recovery, T1 frozen
|
| T1 will not spin up. Warming up cold box. |
|
Thu Jul 20 02:59:06 2006, Doug Preddy, Quench Recovery, T1 still not starting
|
| I will leave the cold box to warm overnight and try it again in the morning. |
|
Thu Jul 20 08:18:31 2006, Doug Preddy, Quench Recovery, T1 started
|
Started flow to turbines. Both started. T1 seems a bit slow. HIC110 at 0.85
SI110 = 4100.
Cool down started. |
|
Thu Jul 20 11:01:09 2006, Willy Andersson, Quench Recovery, Opened up warm return valves CV151 and CV153
|
Mu2 pressure was just about at trip point due to trapped volume of helium
warming. So opened up warm returns to bleed off pressure and prevent it
from rising. |
