Entry  Wednesday, May 16, 2012, 16:01, Anders Mjos, , , , , , , Problems/Solutions, Loose chip of insulator material detected Ceramic_Chip.pdf

 A chip of insulator material was detected below the lower target insulator stand-off (attachment - left picture). The chip may come from the tube heater insulator above (attachment - right picture). The chip will be further investigated when the target is removed.

Entry  Wednesday, May 16, 2012, 19:55, Friedhelm Ames, , , , , , , Problems/Solutions, Hall probe reading wrong 

During the mass scan today it was discovered, that the mass calibration was off. Further investigation showed, that the Hall probe readings are a factor of 1.31 lower than during previous measurements. A fault report has been issued to controls.

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.
