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 
supposition is that while the main header was turned off, the diff. pump 
under the solenoid tripped. When I looked at it this morning the 
compressor was off and the vesssel vacuum was very bad. The PLC connection 
to EPICs is down, so I can not restart the vacuum system yet. Mike Leross 
is looking at the problem. 
There was no trip signal to the main control room. It looks as though the 
control room signal was bypassed downstairs. 
The power supply fault light was on on the QRL panel, but I okayed Bob 
Hilton locking out the power supply in order that Q3's water leak can be 
repired. Shutting of the main breaker may have turned on this light. The 
other possibility is that the power supply was not ramped down and shut 
off properly.

Recovered the vacuum in the solenoid, then started the compressor.
Started flow to solenoid in parallel warm return.

CR_6KS_M down to 11 K.
Switched to series mode.
Started small flow to power leads to get them cold.
HIC142=0.6        Later open HIC142 wide open.
Raised discharge press to 11.4 barA.
Letting LHe level build.

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 
compressed air. On fist trip logger LED # 8 and 16 were lit. Restarted 
compressor then start flow to cold box, start turbines, start // warm 
return until temps returning back from solenoid were <= TIC121 then 
switched to //cold return mode. Opened cv155 to 0.88
Solenoid temps at 24K and starting to trend down.

Keep IT safe boys

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.

started flow to solenoid in parallel cold return.

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.

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.
Started cooling in parallel  cold return.

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 
suggests leaving the system in reduced // cold mode overnight.

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.

Powerleads appear stable.

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.

Solenoid Quenched on C1 temp. It went above 5K. Shut off compressor. 
Restarting system @ 12:15

T1 will not spin up. Warming up cold box.

I will leave the cold box to warm overnight and try it again in the morning.

Started flow to turbines. Both started. T1 seems a bit slow. HIC110 at 0.85 
SI110 = 4100.
Cool down started.

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.
