Temps of flow returning from solenoid flat lined at about 10K.
Gradually closed CV155.
Then switched to series cooling.

Main compressor tripped, refrigerator shutdown. Checked with experimentors 
and main control room, no indications of power bump etc.

Restarted compressor, // warm then // cold return. One of the MV5x valves 
frozen open, had to de-power valve  a couple of times to get it to seal.

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 
levelson the monitor, it seems everything is stable now. I wonder if you 
could let us know what time we can have beam again? Would you please send an 
email to kghandi@mta.ca if you know the answer? You can also reach me at my 
cell# (506)961-0802 any time.

Thanks

Khashayar

02:30 this morning got page from operations.
Looked at system online, appears that there was a powerlead overtemp
that caused the quench. Compressor still running. After arriving to 
work set system to // warm return mode to cool down transferlines. Lhe 
level starts to boil away. Switch to // cold return mode. Discovered that 
seem to get better cooldown rate by not opening supply valves to solenoid 
fully. // cold return valves are fully open but both CV143 and CV146 are 
only open to 0.55 giving mu1 and mu2 inlet pressures of 2 barA. Getting 
good cool down rates and even building LHe level.

04:25 C1 down to 8K, C12 at 7.5K, C6 at 7.5K, 6KS_M at 10.5K

Leaving system cooling in // cold return mode, cooldown rates still good. 
Had flow on to powerleads since re-starting cooling flow to solenoid.
Either I (when I return to work later this morning) or Doug will do the 
switch to series mode.

Switched to series mode at about 7:45.

power leads cold 50% liquid.
Turning on power supply

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

Compressor still on. Starting flow to solenoid

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.

Powerlead temperatures have bottomed out, energizing solenoid to 300 
amps, ramp rate 60.

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.

Don't Panic -- There was no quench. I am testing the e-log.
I have added Kevin's name and e-mail to the M9 e-log. He will be e-mailed 
when a quench recovery log is submitted. His name is also included in the 
Author's list. 
Thanks, Doug

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.

Solenoid quenched this morning on power lead temp (I believe).
I restarted it at ~7:00, but the capacity control for the compressor would 
not respond. I shut the system back down and checked as many relays as I 
could. I then restarted the system and it is now cooling. I will go 
through the wiring diagrams and see if I can locate the bad relay.

Various start up problems :
MV51 stuck open. Finally got it closed by hitting the valve with a hammer.
Vacuum is bad in cold box as MV902 tripped closed.
Vacuum in solenoid has gone bad. Suspect boil off from inside solenoid. So 
far it is not recovering.
Previously T1 would not spin up - frozen.
