solenoid tripped on power lead temp. I was here and caught it. System 
cooling.

Compressor still on. Starting flow to solenoid

The power lead temperatures have been climbing at a rate of ~ 0.02K very 8 
hours. The negative lead started to show some rippling this morning. The 
positive flow had dropped from >250mm to 240mm. I cycled CV142 and the 
temps dropped slightly. The negative ripple is gone and the positive flow 
is back to >250mm. 

I ramped down the solenoid power suplly and shut off flow to the power 
leads. I will allow them to warm up and (hopefully) recover the flow rates. 
I am also regenerating the M9BCP@ cryopump.

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.

The power has been out for about 24 hours. Recovering coldbox, solenoid and 
beamline vacuum.PLC is down for the vacuum system. Started compressor and 
am flowing warm helium through the soleniod to warm it up while the vacuum 
recovers.

I have installed a new control computer at the M9 solenoid control panel

Starting the vacuum systems in the coldbox and solenoid.

I could not control the vacuum devices using EPICS. The buttons could be 
pushed, but nothing would respond. The PLC was in local mode. Thumbwheel 
to 100, push On/Open button to put it into remote mode.

Startewd compressor and purifer today.

Started flow to turbines at about 10:00 in parallel warm mode.

Solenoid cold, power leads cold. Alarm handler started.

The quench relay logic controller was not functioning correctly. It showed 
a "Trip" light and no other lights. I cycled the power to the controller 
and it now seems to be working properly. This did cause a quench and I am 
now recovering the system.

The PLC Limit switch power supply was tripped off on Saturday. I came in 
and reset it and restarted all the vacuum systems that had tripped off. 
The power leads were found to be warming up. This morning they were at ~ 
45K. I stopped flow to the power leads and will allow them to warm up 
above 80K and then will recool them.

Power supply initially would not ramp up. I exercised the rate control 
selector switch and found that the power supply would ramp up at only the 
30 minute setting. It is ramping up at a rate of about 60 minutes.

Power lead temps have been slowly increasing over the last wekk. I ramped 
the solenoid down and am warming the power leads to >80k.
