Entry  Thursday, June 28, 2012, 15:14, Aurelia Laxdal, , LP-FEBIAD, , , , , , Quick check 

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

Entry  Thursday, June 28, 2012, 17:00, Pierre Bricault, , LP-FEBIAD, , , , , In progress, Cathode heater reached its value of 230 A and stoped. good test. 

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

Entry  Friday, June 29, 2012, 08:57, Pierre Bricault, , LP-FEBIAD, , , , , In progress, Continue cathode heating 

 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.

A short in the anode has developed during the heater ramp up. Increasing the current limit did not cure it. Start heater ramp down to investigate.
