status = Making liquid ito LHE dewar


<!-- Date: Tue Nov 9 07:10:32 1999 -->
Looks like the wet regulated well all night. Setpoint was set at 30%, actual indicated dewar level was 29.2 and the wet is regulating. I raised the setpoint on the wet 5%.

valved off the tube trailer to do a rate of drop on Babs& Labs to determine how much liquid we are making. Found tube trailer at about 2-300#. I called CHL, they will send us tt#172, we send them back tt#417. I called hack to arrange swap of tube trailers.

I cut back on pvsc (ln2 subcooler) because we have a lot of liquid coming out the vent.

Established LCW flow to the Assembly Hall bus. Flushed the system first; water looked clean.

Halted lead flow. There is some ice on the B lead flag inside the  inert box from condensation that got inside. Hoping it will melt.

The ice melted, but in the meantime an LCW leak developed.

The CDF_S1 node (Cryo & Gas)had to be restarted because for some reason FIX lost communications with the network. Restarting restored the unknown problem.

Set up magnet flow as follows:  The normal flow set point can be set from a picture.  During magnet ramping the set point will be increased 20%.  After ramping it will decrease to normal.  If R_BOBCNT_C exceeds 15K, then PVMF will open fully and remain so until the control dewar reaches 30% level.

Steve and Chuck hooked up the stacks for the relief valves on the control dewar. We disconnected tt#466 and connected tt#172@2000# to babs. I have arranged to have tt#466 taken back to CHL in the morning. FIMF is working, I reset the stroke and zero for pvmf. 
Steve and Chuck are working on the LCW on the platform.

We had one fitting to fix on the LCW system. We will leave it valved off until the epoxy we used on it sets up.

Investigated report of unusally loud noise coming from Tank 18.  Tank 18 was at 43 psig with its back pressure regulator blowing away. The pressure building heat exchanger was completely covered in frost. The Tank 18 pressure bulding regulator bypass was closed and the regulator inlet and outlet valves were open.  After the pressure dropped, I cracked the inlet valve on the pressure buiding loop. 
 
The tank 18 pressure building loop at times appears to not work at all.  This evening however, it worked too well.

in previous entry I should have written that closing the inlet to the pressure building regulator lowered the Tank 18 pressure.
