Einzel Lens voltage: 14000 V

Einzel lens current: 49 microAmp.

Just a quick check at the Test Stand:

1. The system operational (  white out not present ) with TSH:TBHT heating in progress.

2. Started the Archivers: for Source and Optics.

3. Removed bypass on TSH:SV5 since it's not necessary anymore.

4. Currently: TSH:TBHT=107A

Now ramp cathode current up to 290 A. The total current out is 1.e-7 A.

 This morning the pressure was 3.5E-7 T. Current at 275 A is 30nA.

Continue cathode heating to 290 A during meeting.

Start seeing some electron current from the cathode around 275 A.

Rick put the helium bottle back in the rack.
