Purged the gas lines, turned on the HV and started the heaters for CLT FEBIAD: TGHT up to 580A and TBHT up to 230A.

Problem: Some devices turn off unexpectedly and sometimes without any obvious trigger. In the past, the only time this was an issue was during mass scans. Now with the automation of measurements, this is a major problem as it prevents longer parameter scans.

Thursday, August 05, 2021, 08:00: Kevin setup the CANBUS snooper by hooking it up on the magnet card loop port.

This device tracks the network so if any error happen it will be captured.

Thursday, August 05, 2021, 09:39: Test unsuccessful. No device turned off (I should be happy XD)

Thursday, August 05, 2021, 09:40: Will run the test another time

A PC was setup near the old magnet power supply (20210806_150334.jpg ). One of the software run smoothly but the other more useful one fails to connect to the usb adapter.

 Friday, August 06, 2021, 14:52: Fixed issue with  the usb adapter. With this, the CANBUS traffic can be store and inspected to catch any error on the communication (Annotation_2021-08-06_144737.png).

Friday, August 06, 2021, 14:53: Loggers are running. 

 Friday, August 13, 2021, 11:07: I forgot to input the feedback  from Kevin:

"33 errors out of 10,300,00 transaction seems statistically insignificant to me. "

From the devices tripped,

"Most of the tripped supplies are located on the front side of the rack, the original test stand controllers"

So maybe the issues could be

"Compatibility issues with the old and new? The newer supplies are all daisy chained, should we upgrade these to the tap boards?

Should the old controllers (original test stand appear to be MK supplies) be upgraded (do we have enough)?"

2 C-Seals installed with SS springs on water blocks. The SS springs are also used in the module.

The ground connection between B and F (ISK4523D Rev 6) was found burnt off. It will be switched out as per CATHODE BIAS configuration (ISK4563D Rev 3) by Ray D.

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.

Pressure:

Ramping up:

• Second attachment - bias at 50kV
• Third attachment - bias at 60kV
• Fourth attachment - bias at 65kV

Pressure has been slowly falling since we started this test - now down to 8.7e-7

Spark after 10 mins, see attachment 5. Very slight vacuum jump (8.5e-7 -> 1.2e-6) and bias current jump (36uA -> 113uA). Tripped TP6 and the steerers, as usual. Bias current read back more erratic afterwards (see sixth attachment).

System has been stable for 20mins, though current on bias is still more erratic than before the spark. Increasing He leak rate from 7 to 7.06 to bring vacuum back up to 2e-6 (see attachment 7). No effect from increased pressure.

Tuesday, March 13, 2018, 05:52: Power off.

Tuesday, March 13, 2018, 05:56: Waterlines purged

Tuesday, March 13, 2018, 05:57: Ion gauge, Turbos off.

 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.

The power supplies were "de-dusted" yesterday by Ray Dube and team. 

Wednesday, July 24, 2024, 14:07   Changed beamline window to DUV window (window at magnet for target source viewing)

Vented beamline and removed ARIEL emittance meter. In the process of swapping components, beamline left vented until Monday when we will finish the job.

Tuesday, August 25, 2020, 07:07: Beam line side of the TS appears to have tripped? Open BV6 & BV2.

Tuesday, August 25, 2020, 07:15: Beam line side TP6 & TP2 on.

Tuesday, August 25, 2020, 07:16: Venting Chamber side

Trip appears to have occurred at 6am on Saturday.

Contacted MCR. Power bump occurred.

Backing pressures TSG:CG1A/B are fluctuating between 0.02 and 0.05 since Sept 17th at ~17h. Expected values <0.01.

Pressure around 140 mTorr. The pressure started increasing early November 2nd. Will continue to monitor.

Tuesday, November 12, 2013, 09:51 UPDATE
 Backing pressure further increased to ~ 350 mTorr over the weekend. Vacuum group has been informed and will replace the pump this week.

 The backing pump (TSG:RP1) was replaced yesterday by Anthony Ip. Backing pressure is down to 1 mTorr on TSG:CG1A

TSG:RP1 backing line pressure is >200 mT. An e-fault has been submitted to have the roughing pump replaced.

Friday, April 24, 2015, 13:13: Pump replaced by vacuum group.

Tuesday, September 10, 2024, 16:21:   Target installed in test stand by Brady

Tuesday, September 10, 2024, 16:21: roughed down and turbo pumps now on.

Tuesday, September 10, 2024, 20:27   Pressure at 4.9e-6, increasing TGHT TBHT to 580A/230A at 1A/30s

Wednesday, September 11, 2024, 10:00 The TGHT TBHT parameters were mistakenly reversed during heating. TBHT was dropped to 230A and TGHT increased to 580A at 1A/30s.

Wednesday, September 11, 2024, 13:50 TGHT TBHT at 580 230.  Increasing BIAS/EE/EZL to 30/2.5/13 kV.

Wednesday, September 11, 2024, 14:36 At high voltage, on FC0 there is an output beam current of 1.85e-7 A.

Wednesday, September 11, 2024, 14:49 Mass scan recorded.   2024-09-11 HPTiC-24D - scan 1.txt ... FC6 problem with recording background level data persists

Wednesday, September 11, 2024, 15:53  increasing BIAS and EZL to condition high voltage 

Wednesday, September 11, 2024, 16:32 at 37kV (EZL 22kV), TGHT timed out and cut the current to the target. I elected to leave it cold rather than suddenly reheating it, and am cooling down TBHT at -1A/30s, while continuing to increase BIAS for conditioning.

there have been no sparks at all and I'm unsure of what precipitated this event. None of the 'trip indicators' on the TGHT panel lit up during this event. I will bring this up with Keiko/Roberto tomorrow Sept 12.

Wednesday, September 11, 2024, 17:06  one spark occurred at 49kV

 Wednesday, September 11, 2024, 17:15  now at 50kV, EZL at 33kV.  Over 30 minutes there was just one spark at the HV bias.

Wednesday, September 11, 2024, 17:50  decreasing high voltage elements to 0 0 0. 

The fan in the EZL power supply is making a terrible noise - keep an eye on it, it sounds like it might give up soon.

Monday, April 23, 2018, 10:47: The back panel was opened. Original entry stated EZL power supply issue. Corrected to BIAS PS. High voltage group notified. Fan replacement required.

Monday, May 14, 2018, 13:20: BIAS fans, external an internal were replaced. Re-installed @ TS.

Monday, May 14, 2018, 13:26: BIAS ramped up to 10 kV. Response ok on epics and locally on the PS. No odd noise on the fans either. The issue appears to be fixed.

Wednesday, February 07, 2018, 08:40: A 75 kV Glassman power supply was installed in the rack for use in further HV testing.

-The 75kV power supply is linked into the keyed interlock system. The key & switch labelled BIAS/EZL will unlock it.

-The PS is currently not connected to the epics controls and can only be adjusted manually.

-The old Glassman supply is disconnected and removed from the cage.
