Entry  Thursday, June 28, 2012, 11:27, Pierre Bricault, , LP-FEBIAD, , , , , In progress, Cathode heating in progress, pressure 8.3e-7 T 
 
Entry  Thursday, June 28, 2012, 11:29, Pierre Bricault, , LP-FEBIAD, , , , , In progress, Lost all cnntrol interface, complete whiteout of the epics system. 
 
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, 17:18, Pierre Bricault, , LP-FEBIAD, , , , , In progress, Leave the cathode heater at 275 A overninght. 
 
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.

The helium bottle was found empty.

Rick will refill it and hook the leak detector on the system to find out

if we have a leak on the line.

 

Entry  Friday, August 10, 2012, 12:44, Pierre Bricault, NA, LP-FEBIAD, , , NA, NA, In progress, FEBIAD test 

Rick put the helium bottle back in the rack.

Waiting for status of the gas lines.

 

Entry  Friday, August 10, 2012, 15:29, Pierre Bricault, NA, LP-FEBIAD, , , NA, NA, , finishing the gas installation and its pump 

1524H Start small pump.

1529H stop the pump.

 

Entry  Friday, August 10, 2012, 15:57, Pierre Bricault, , , , , , , ,  

Test high voltage to 30 kV ok

Test gas valve open at 6.1 V

Test Ne leak ok

Will run test from home.

Entry  Saturday, August 11, 2012, 16:18, Pierre Bricault, , , , , , , , Test FEBIAD anode biased at 120 V 

The ramp up finished.

I have 3.35E-6 Amp out of the source on FC0.

Vacuum  4.3 E-7 T increase Coil current to 40 A. No effect on vac.

Increase coil to 50 A. Vacuum still good.

I will continue from home..

Lost communication with EPICS. Came in reset the ...

So far no luck.

 

Entry  Sunday, August 12, 2012, 22:07, Pierre Bricault, , , , , , , In progress, FBIAD test 

The reset restored the control.

But magnet supply does not put any amperage out.

Try turning it off and on. No chance.

I gave up. See tomorrow.

This morning I try to contact PS group no one answer. Dan Louie is in vacation.

I went into the can diagnostics panel and reconfigure MB1 power supply.

This worked.

 

Entry  Monday, August 13, 2012, 14:26, Pierre Bricault, , , , , , , In progress, FEBIAD test 

I am done with the FEBIAD test (anode biased)

We will swap the bias now to the cathode and change the polarity to negative.
