The first plot is an Acnet plot showing 40 minutes of contamination in the BA/B0 gas (plot range is 0 to 20 ppm). The second plot is our arc cell reading with a range from -2 to +2 ppm. The adsorber did a fine job!

It was more like 20 to 30 minutes.

Elect. turn off montor gen. 3 & 4 to do clean up work  
( remove fuse on one leg) montor gen are running now 
everthing is OK.

CDFS1 and CDFS2 hung up. S1 complained about a network transaction. They actually required a hard boot. Back up.

The solenoid is ready to be powered for tests of transducer performance and various other tests. The Watt can was pumped briefly.

There was a brief flam. gas alarm that went away before I could see what it was. Nothing showed up in the summary.

West silicon alarms are silenced in case flow trips.

<pre>Performed a series of tests with steel and solenoid 
 
1.   Looked at clc gains by making measurements with solenoid off, solenoid on -- steel back, and solenoid on and steel forward.   They did  not see a change in the gain measurements.  So problem is not caused by magnetic field  
 
2.  Jim E. made 3 "covers" with mu-metal for the silicon pressure transducers.   They were installed on the two absolute pressure transducers (supply) and the SVX BH1W (DPT).   They did NOT trip.   (Solenoid was powered and steel moved into position where we left it there for ~30 minutes)   SVX BHW2 did trip. 
Looks like this shielding will do the trick. 
 
Left the system with all steel pushed BACK and the magnet off.</pre>

The solenoid is powered down for an unspecified amount of time.
