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 |

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.

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. |
