switched to parallel cold return earlier this morning. Vacuum is 5 x 10-5.

Solenoid quenched on power lead temperature last night at about 6:00. I 
restarted flow to the solenoid in parallel cold return. Switched to series 
mode and am building liquid. 

power lead temps caused a quench at 8:30 this morning. Recovery of system 
and flow to solenoid was started by 11:00. Solenoid was switched to series 
cold at 3:00. Solenoid and power leads were cold at ~6:30. power supply 
was to be energized by experimenters.

This is a test to make sure the e-mail works.

The solenoid tripped off this morning due to pwer lead over temp. The 
compressor was also off. I restarted this morning at about 8:15 in 
parallel cold return. Switching to series mode at 3:40.

recovered system and energized solenoid at about 6:00 this evening.
At 9:30 power lead temps quenched solenoid again. MV52 stuck open during 
start-up.

LHe level~50%. Still have a slight ripple in the power leads, but they are 
cold enough to power the solenoid. LHe_in varies between 10.7K - 11.3K.

compressor off due to cold box trip at 6:00 this morning. Restarted system 
and started flow to solenoid in parallel cold return.

Kevin and I were at the Sulzer panel when the system quenched 2. No 
obvious reasons. Restarted the system.

There was a fluctuation of the positive lead temp with no flow going to 
the power leads.

Refrigeration sytem shut off at ~ 12:30 today. No apparent reason. Only 
light on was a cold box fault. 
Restarted in parallel cold return mode.

And started flow to coldbox,solenoid in parallel warm return.


Tuesday evening theree was a 2 hour power outage 19:00- 21:00. No call 
made to M9 operator.
Wednesday tried to recover vacuum. Started cool down Thursday morning.

switched to series mode.

Solenoid cold. Added two bottles of helium. Allowing to stablize. Will 
ramp power supply in half an hour.

I received a page at 1:30 this morning. The power lead temperatures were 
climbing. Cycling CV142 did not fix the problem. The solenoid quenched at 
1:50.
Restarted flow at 2:45 in parallel cold return.

Not really a quench recovery, but...I wanted to send this out via e-mail. 
The contactor for the compressor building fan failed recently. Randy is 
looking after it, but parts will have to be ordered. The big door should 
stay open until the fan is running again. 
Other than the fan, the rest of the system weathered the weather okay. 
It's up and running until Wednesday morning. After maintenance day, we 
should ramp down the solenoid power supply and leave the refrigerator 
running. We can do some training and maintenance at this time. I would 
also like to keep it cold until blocks can be removed so we can pump out 
the cold box.
