Restarted the PC at the Test Stand.
Restarted the Archivers; currently pumping down the separator area.

turbo pump TSG:TP1B has tripped off. Cannot be restarted. Fault report to vacuum. Everything switched off again

Entry  Friday, July 06, 2012, 11:04, Friedhelm Ames, , , , , , , , source tripped off over night 
A big vacuum excursion tripped the source off at about 1am. The vacuum did not fully recover afterwards only down to about 1.3e-6T. Ne leak has been
closed and vacuum went down to 6e-7T within a few minutes. After the trip the current of the magnet stayed constant. Fluctuations may have been caused
by high voltage sparks.

The current at the magnet power supply TMS:MB1 shows fluctuations every 1-2 minutes. The same can be seen in the Hall probe read back and in the beam
current at Fc6.

Entry  Thursday, July 05, 2012, 10:59, Friedhelm Ames, , , , , , , Problems/Solutions, water tripping in front of HV power supplies 
Found some water tripping in front of the high voltage power supplies rack from the water lines at the ceiling. Plastic sheets have been put on top of
the racks and MCR has been informed.
Entry  Wednesday, July 04, 2012, 15:37, Anders Mjos, FEBIAD anode end cap test, , , , , , In progress, Pumping down  photo_8.jpg
Replaced grid containing ring (target side) with new ring. No contact between target and anode measured in lab.
NOTE: While closing up the VCR fittings the tube rotated causing the tube to flatten in a bend. This may reduce water flow on the heat shield circuit.

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.

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.
Entry  Thursday, June 28, 2012, 17:18, Pierre Bricault, , LP-FEBIAD, , , , , In progress, Leave the cathode heater at 275 A overninght. 
 
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  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.
