Wednesday, June 19, 2019, 08:35: Purging / venting.

Restarted archivers.

The new controller (XGS-600) installed for IG6 use a different voltage to pressure conversion than the previous models. This causes a discrepancy between values in EPICS and the value displayed on the controller. An e-fault has been submitted.

Friday, December 18, 2015, 14:40: EPICS updated and restarted.

TMS:IG6 had continued communication errors post power outage & would not switch on. After a power loss, IG6 switches automatically to Filament 1. Filament 1 is burnt out.

Thursday, January 24, 2019, 08:14: TMS:IG6 fixed. Switched from Filament 1 to Filament 2. FIL2 runs ok.

Instructions from Edi:

-Using the + / - keys move the cursor on the control box to select FIL2. The control box is located above the beam line turbo pump control boxes / inside the black cabinets under the TS.

-Press ok to switch FL2 : ON

-Turn IG6 on with the computer (EPICS) before it times out.

-Now IG6 is connected and can be switched on / off from the computer.

Will went chamber to replace the filament.

High winds caused a brief power outage that completely shutoff the ISAC test stand.

Locked out the power.

RGA checked & shutoff complete

Epics failure, computer restarted.

Thursday, December 20, 2018, 13:52: Shutting ISAC test stand down for the holidays. Checking Epics & operation first.

Thursday, December 20, 2018, 13:55: Roughing pump operating. Turbos left off. Backing valves opened. Epics whiteout on TS sources & optics.

Wednesday, December 20, 2017, 11:22: RGA shut off completely.

Friday, January 26, 2018, 11:08: New Helium tank installed inside the Test Stand.

-The 'Full' tag remains. The He tank was not opened.

-The old tank was placed beside the Test Stand beneath/beside the power switch.

new ion guide laser ion source installed. Pure target container without targetmaterial and without surface ion source.

Heat up to 580A for heat test of all components. Distance between target and repeller < 1mm

13:15 start heating TGHT, 1A per 30sec vacuum below 2E-7T

14:50 reached 200A at TGHT (1.5V readback same as frontpanel), vacuum now 2.9E-7T, proceed on to 400A

16:10 TGHT 350 A (setpoint, readback stopped at 269A) and 3.4V readback, sudden increase in vacuum from 4E-7T to 5.5E-7T and larger fluctuations, give it 10min

16:22 vacuum back to 4.4E-7T but some occasional vacuum spikes , proceed to 400A

17:00 at 400A / 4.13V, vacuum hit 2E-6T in between which delayed the heating, now decreasing, will goto 410A for half an hour and then 385A over night

Dec 12th

8:30 3.3E-7T Vac at 385A, goto 420A

8:50 7.5E-7T Vac at 420A, goto 450A

9:20 1.7E-6T Vac at 450A, goto 470A

10:00 1.5E-6T Vac at 470A / 4.5V

11:30 1.1E-6T at 520A/4.56V

Wednesday, December 12, 2012, 11:46   1.7E-6T at 550A/4.58V

Wednesday, December 12, 2012, 14:31 

     580A reached,  Vacuum dropped from 1.8E-6T to 5.8E-7T in 2h

     voltage read back is wrong as well Panel readings are 572A/6.99V (read back values in EPICS are 248A/ 4.6V) 

Wednesday, December 12, 2012, 14:47 6.5E-7T at 592A/ 7.31V (Panel readings)

Wednesday, December 12, 2012, 15:01 there is no contact of the target to HV GND (especially the repeller), the target can still be biased to 5V

Wednesday, December 12, 2012, 19:48     5.9E-7Tvacuum is slowly going down now

Thursday, December 13, 2012, 00:23   5.5E-7T, start cooling down

Short summary on results of first heating teest with the Ion Guide Ion source:

The Ion source is still in good shape, nothing was effected by the heat. Just some deposition in the repellers and the exit electrode

The capton wires used for  wiring the electrodes had some problem with heat and went black and got brittle - for the next test we will ad a Ta schield at the side of the source to prevent radiation inside the source.
