Today we started to purge the miniskirt with nitrogen. For now use only nitrogen, because we do not have approval to purge with argon/ethane.

Silicon Cooling tripped about 11:45 this am.   Both chillers tripped off.   After investigation, it looks like the chilled water valve 9001 closed momentarily.  Once the chiller was restarted, svx cooling flowed fine.   ISL tripped with high pressure in the port cards.   Quadlog shut down the racks.   Don't really understand what happened here.   Will talk to Rich about putting in a delay between flow and ps enable to give siemens a chance to trip off the system gracefully.

ISL mock-up of cooling system installed on ISL chiller.  We ran it for a while and made measurements.  Did not see any flow problems with the mock-up.   We still have more tests but it looks like either we have real blockages or else the temp measurements are not accurate. 
 
In making these tests we (Rich Stanek...) made a little boo boo.  We transferred water from svx supply to isl air separator.  DOH!  So now I am transferring water back from svx air sep to ISL.   Should take about an hour.

Had a svx- isl water alarm water levels were out of tolerance, Rob was equalizing the tanks one got over filled, all tanks are ok at this time.

Dumb mistake number 2 by Rob.   Transferring liquid from isl to svx cooling.   Got busy with other problems and transferred too much!   DAMN IT!   Forget the 1/4 inch tubing, I hooked up 1/2 inch tubing and did the reverse transfer!  No I can't walk and chew gum at the same time...
