Wednesday, June 19, 2019, 17:13  Ferran and Fernando tested the 9-pin connector to have a reading on a thermocouple following the connections used by Aurelia (see elog 721).

Wednesday, June 19, 2019, 17:24: Test succesful!

Monday, June 24, 2019, 15:25: Current quadrupole polarities:

Monday, June 24, 2019, 15:35 : The polarity on TMS:Q3 is reversed. The top and bottom poles should be at a positive voltage similar to TMS:Q4, however a negative tagged cable is connected to it.

Monday, June 24, 2019, 15:39 : Swapping the cables on TMS:Q3.

Tuesday, June 25, 2019, 16:15: While inspecting the 9-pin connection with Ferran, it was noticed how two braided cables were burnt out pretty bad to the point they were separated in half (see attached pictures).  Additionally the plastic insulator for the anode wire was melted.

Tuesday, June 25, 2019, 16:30: Braided cables need to be changed and anode wire redone. 

Tuesday, June 25, 2019, 17:16: Wondering if this happened during TM4 source tray conditioning given the following entries in the elog (entry 725):

Monday, June 03, 2019, 09:51: BIAS down to 50 kV. Burnt plastic smell lingering. Wait* 

Tuesday, June 04, 2019, 10:29: Note* Minute fluctuations of Anode current have ended after the spark. Also slight 'Burnt' smell noticed around the test stand area.

See elog 737 

Thursday, June 27, 2019, 09:45: The cables showing burnt marks were changed with new ones on Wednesday 26th. The grounding cables were insulated with yellow heatshrink. The anode wire connection was redone.

 Tuesday, July 02, 2019, 18:24: A blind is installed  on the FEBIAD gas line (see attached picture)  to rule out the possibility of  gases entering the TIS.

Thursday, July 04, 2019, 15:00: TBHT insulator was swapped out on the source tray side. 

The old one is very chipped.

After submitting a fault report (FR - ISAC Fault 12461) a Work Permit was issued (WP - C2019-07-19-1),

Controls tunnel the faulty signal to another ADC by removing signal no longer used at the Test Stand.

Test successful with a constant current power supply in the range 1 nA-40 nA.

TBD: does this work with beam?

Wednesday, August 07, 2019, 15:12:  Arthur helped inspected the electric connections on the TS.

One of the coil positive waterlines  was touching a HS waterline. Manually adjusted them to have a better clearance.

Inserted a used (heating) LP-FEBIAD target with a basic heat shield assembly with no end plate foil on the window side to observe heating. The P2N Coil / TGHT connections were added.

Test whether the TS connections are affecting the P2N heating or if it's the P2N target itself.

-Heat the TGHT only, observe, then ramp down.

-Heat Coil only, observe, then ramp down.

-Heat TGHT w/ Coil, observe, then ramp down.

Note* Heating should be even across the target. Elog & take pictures.

NO HV ALLOWED!!!!

Thursday, August 08, 2019, 09:05: Roughing.

Thursday, August 08, 2019, 09:14: BV1A closed to allow pressure stabilization. Opened about within 2 seconds later with BV1B.

TSG:CG1A & TSG:CG1B do not appear to be pumping down efficiently - May need to swap out TSG:RP1 after this test. Last done April 18, 2018. elog: 655.

Friday, August 09, 2019, 11:18: TGHT and TBHT power supplies ramped to 150A each, total of 300A in the target

Friday, August 09, 2019, 13:12:  Target glows symmetrically. TGHT and TBHT ramped from 150A to 200A each for a total of 400A on the target

Friday, August 09, 2019, 14:05: RGA error.

Friday, August 09, 2019, 14:08: RGA Restarted.

Wednesday, August 14, 2019, 09:17: Revising the archiver, on July 8th at around 4 am, the vacuum on GC1A increased from normal levels to around 0.2 T. This happened while the target was held at a high combined current from both TGHT PS and Coil PS. See screenshots attached.

Thursday, August 15, 2019, 09:57: Vacuum is only around 1.06e-06T.  Turbo pumps off. Ion gauge off. 

Tuesday, August 20, 2019, 08:59: Ion gauge acting funny. CG1A unplugged & re-plugged in. Seems to work now?

Thursday, August 15, 2019, 16:17: Q FT undone to remove the connection to the 9-pin

The idea is to change the cables to have individual signals. This will allow 4 thermocouple readings.

NB: The FT is not vacuum tight as of now  (gasket needs to be replaced and flange needs to be tight)

Thursday, August 29, 2019, 14:47 : Changing back to the nominal wiring 

Thursday, August 29, 2019, 17:01: TIS changed to Ferran's heat shield.

Wednesday, September 04, 2019, 17:33: Final auto-ramping of the day TGHT / TBHT to 290/ 290 A @ 4 A/min. Vacuum stable@2.7e-7T

NB: Ferran's HS doesn't have an extraction electrode. Since the purpose of the heating is to "baked-out" the system, this is actually great as the shine will go downstream the beamline.

Thursday, September 05, 2019, 08:05:  Auto-ramping TGHT  to 580 A @ 2 A/min. Vacuum stable @2.97e-7T

WP: C2019-10-23-2

ISAC test stand power supply MB-1 leak.

Water can be seen underneath and behind power supply cabinet. Repairs as per WP.

Friday, October 25, 2019: Power supply operational. AM

Restarted TP. Note that CG1A is above 50 mTorr. CG1B shows 15 mTorr

CG1B showed 8.9mTorr while EPICS shows 14mTorr.

After reconnecting CG1A, EPICS shows 16mTorr. Anthony suggest replacing the gauge.

Wednesday, October 30, 2019, 14:49: John C. changed the polarity of the anode power supply to negative, and Fernando M. rewired the cabling on the service cap.
