Solenoid is cold, full, and stable at 4650 amps.

Toured mechanical room. Found (LCW) expansion tank 1 high with all 4 level lights on. Ifix page indicates "NORMAL". I was curious to see when this bit changed, but since the solenoid is powered I'm not killing any cats today so I drained the tank down to just above mid-level. (Magic marker notes on the tank indicate that it should have been in alarm.)

Put cryo valve PVLF in auto.  This ball valve will open when the pressure difference PCDEW-PVLF is less than 2.5 psig.  Once open, the valve wil not close until the pressure difference goes above 3 psi.  PVLF, when open, will vent helium into Dupage county.

Performed the following on Silicon cooling today: 
1.) Added 40 gallons of glycol to the SVX cooling system.  This is about 26% glycol.  Will take another reading in the morning and then add glycol to get a final mix of 30% glycol. 
2.)  Changed the elements in the SVX cooling water filter.  They were a little discolored and there was some particulate in the bottom of the filter housing. 
3.)  Have put the spare chiller on the ISL cooling system.  Have also lowered the temperature from 10 to 6 C., per the request of the Silicon people.

<pre>Walt J installed new quench protection module (5a and 5b) 
This new system utilizes both new flux coils.   At the moment, we are now quadruply redundant.   If we lose a voltage tap, we can reconfigure quench protection through the endrack.   Walt tuned the system.   Trip limits are set at .52 (5a) and .55V (5b) respectively. 
 
Now powering the solenoid in preparation for this afternoons shot.</pre>

On the contro, loop fro PVCP, increased the proportional gain by a factor of 10.  Tis should help keep control dewar pressure more stable.

Had ISL and SVX alarms earlier. Turned out to be Andy.

More alarms: Andy's still working on things.

After Andy rebooted the PLC, we are having trouble with SVX. Both setpoints for chillers went to 16 degrees. Air separator for SVX is 26 inches and the valve to the vacuum pump will not open. Andy paged Rich and Jim E.
