Did the HV conditioning.
Heaters conditioning in progress.
The Hall probe is not working: couldn't pass 35.5 units (readback) or 50.16 units (setpoint) at field -3710G. |

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. |

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.

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. |
