Type: Update 
Category: VAC 
Subject: Pumpdown at 26hrs 

 Cold cathode gauge CC1 -h (horizontal) just coming on 9.2e-5 Torr

P2 is the fore line pressure of the maglev. One can see the 4 Torr load during switching over to turbo pumping.

CC4  5e-9 Torr is the performance of the maglev pumping on the RGA only.

The annuloses are not pumped  now.  They are closed off to see how much outgassing plus leak they have.

Configuration: vacuum normal, annuloses not  pumped

Condition: normal

Precondition: 14 days at atm, IOO chamber north door was taken off as a new entrance, the ETMX chamber was not opened.

What is new in the vacuum system: new P1 pirani gauge, gold plated clean allen wrench and ..........what else was dropped?

Note: the wireless laptop did not fail once all day yesterday. I want to give credit to the person who is responsible for this.
