Gas and cryo systems are running fine no problems this evening. 
the pressure on the argon tank got to be 250psi, I closed the pressure building coil and blew it down to 180 psi.

The control room called and wanted to know about the drip of water off the lead flow lines. It is just dripping cause the fan is blowing on the lines to prevent an ice ball from becoming too large.

The fan increases the amount of warm air that comes in contact with the cold lead flow lines giving up heat to the frosted lines causing a transformation of ice to water (latent heat of fusion). Gravity then causes the liquid water to drip into the catch tray.

The argon tank pressure is 153 psi with the pressure building coil closed.

The CDF systems checklist and mechanical rooms are normal at this time. The oiler on LCW pump #2 looks good also. Argon dewar pressure is 151psig.

I asked KC to reinstall VP2-A on the ISL system and we removed the big vacuum pumps that we used yesterday. I tested VP2-A and it runs just fine. Switched back to VP1-A with VP2-A in standby.

At 1000 amps Rob R. hit the fast dump button.

<!-- Comment: Wed May 16 08;49;02 comment by...Jim H. -->
The PS for the solenoid is locked out.

<!-- Comment: Wed May 16 08;52;23 comment by...Jim L -->
Solenoid is at 16 amps (it's down), Called Bob Sanders and gave him a heads up on it.

We stopped A/E flow to the COT also the Ar/O2 supply is off.

The COT O2 analyzer is disabled also.

Put leads in stand-by !

Test ran the East Dry Engine to double check the controller. Ran it through various speed changes and holding each for 5-10 minutes after it got cold. Worked well ! --> Vacuum in the exhaust u-tube held steady after it cooled down and no sweating was noticed. Shut it down and it's ready for use.

Gas and cryo readings taken. Mechanical rooms look in good shape no problems at this time.
<!-- Author: Bruce -->


<!-- Date: Wed May 16 18:43:27 2007 -->
Readjusted the gow-mac and blew down the argon tank #18 to 175psi. Then I started a gas mix into argon/ethane tank #2 at this time.

Performing procedure #13 on the cot systemat this time.
<!-- Author: Bruce -->


<!-- Date: Wed May 16 20:42:02 2007 -->
Procedure #13 for the cot is complete turned on the tof heaters.Argon/o2 is turned on. the O2 reading for the cot is 236ppm. De3l will sigh the procedure sheet in the morning.
