Fernando

Wednesday, June 30, 2021, 15:09 : Venting

TP1A tripped off on Fernando, seems the backing pressure got too high. Even with PV1 closed the RP1 pump could not get below 200mTorr. Derek from vacuum group came and had a look, and is swapping RP1 out for one of the vacuum group pumps, then will see if they can repair ours.

After not being able to get beam through the emittance meter. I diagnosed that the plates was not biased (reason yet unknow).

I swapped the cables from the plates such that it looks like the picture below. With this, I was able to take an emittance scan with the previous parameters.

Varying the optics affect the shape and position of the emittance so I believe this is a real signal.

Keeping this configuration until I finish my measurement.

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)?"

Saturday, August 07, 2021, 18:02: As mentions in previous entries, the FC0 current oscillates with no change on ion source parameters.

Hence, I came on-site to see if there was an issue with the hardware. Nothing obvious.

Last night there were some sparks that might have cause some issue.

RPMS are shifted toward negative current reading, similar to what we observed when testing TM4 sourcetray.

To rule out hardware issues I swapped the signals from FC0 to FC6 and visceversa.

When the output of FC0 goes to the FC6 controller the readout makes sense, and this behaves as expected with gas on/off.

When the output of FC6 goes to the FC0 controller there is no readout coming out. This suggest, at least to me, that some damage or error is happening on the DAQ side.

I will reboot the ioc expecting to see something.

Things sort kind of Ok but I don't trust it. FC0 reading makes a bit more sense. RPMS remains with an offset

Saturday, August 07, 2021, 20:31: The FC0 reading increase from 7.54e-11 A to 1.64e-8 A starting at 19:32. Also, the RPMS baseleves are not offset anymore, the -10 rd when using the 1 nA scale is back to 0 (normal)

 Monday, August 23, 2021, 09:53: RP1 was swapped back to our original pump. (see e-log 889)

Derek informed that they test it overnight and performed well, and it's a bit slow but it goes down to 20 mT.

Current is at 36 mTorr and dropping.

Monday, August 23, 2021, 10:49: Aaron removed the Extorr RGA and install a blind instead.

When the new RGA arrives it will be changed.

 December 30th, 2021: Water poured down around Isac test stand and probes lab area in service annex extension. problem was traced to a Cracked HVAC coil on SA roof

Fault: 14601 

https://web.accel.triumf.ca/ncr/dbfault.pl?faultno=14601&usertype=unknown&username=&faultgroup=CYCLOTRON&debug=0&btn_submit=Showfault

https://elog.triumf.ca/TIS/Test-Stand/908

Noted on arrival to startup the ISAC TS some cleaning of the area was required. Optics PS & all PS quickly checked. OK / Dry. 

Use caution when HV is to be applied later. Expect conditioning / noise from the cage. 

Connection of TBHT negative to HV common removed (R4 in circuit diagram). Labelled and put in MRO bucket.

Anode connection moved to feedthrough J.

Rewired multipin patch panel. Left some grounded (HVC) wires hanging, should probably make this nice later.
