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

Emittance meter number 2 ready for beam shortly - installed and pumping down.

No beam found by Thursday evening, but beam seems to be coming out much differently than last time. Will check on emittance meter functionality and try to re-tune later.

Ramping things down for the next couple days.

Saturday, April 03, 2021, 10:41 :

Source heating ramped back up, everything back on. Will try to straighten out steering then see if I can get things back in the previous positions.

Saturday, April 03, 2021, 14:59 :

Nothing seems to be working, will vent the beamline and remove the slit.

Saturday, April 03, 2021, 15:36 :

Apparently closing the valve started a vacuum leak that tripped everything in the source. I noticed within the first minute and ramped everything back up, maybe too quickly....

Have now put everything in a holding state, will resume tomorrow.

Sunday, April 04, 2021, 14:17 :

Found everything off again this morning. Ramping back up in the hopes that I can get something done before the whole system trips again. The trips look like water leaks again.

Uninstalled the slit and left it in the bottom of the vacuum box. Swapped the window to the computer side for convenience. Seal on the other side on the CF flange is a bit weird, not sure if it is in properly...

Sunday, April 04, 2021, 18:43

Still no beam. TISA emittance FC won't come back on, so waiting for Mike Rowe to troubleshoot on Tuesday. Will ramp things down all the way, since I expect the vacuum to trip the source before I need it again.

Tuesday, April 06, 2021, 23:43

Found some beam, but looks really weird, like it is cut off. Good enough. Ramped everything down.

IG1 has been spiking randomly, causing everything to turn off. Looks like the water leak is still there.

 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.

Wednesday, January 12, 2022, 16:08 : HV ramped to 30kV, EZL=15kV, EE=-1.5kV

Ramping up to 250A on TGHT, 200A on TBHT. See MassMarkerTest#1 for ramp up values of the thermocouples.

Seeing some beam on FC0, changing magnet settings to Cs to check FC6 then will ramp up.

Thursday, January 13, 2022, 14:22 :  1.3e-10 approximately Cs on FC6. Optimal EE -2700V, slightly higher than standard on EZL.

 Ramping down to Na on the magnet, found 5 pA:

 Started a ramp up to nominal heater values (TGHT-500 A  TBHT-230 A) but too much HV sparking so aborted at TGHT-299 A and TBHT-230 A. Ramped HV down to 16kV to get sparking to slow down.

Ramped quickly back up to 30kV to get FC readings but since there is so much sparking, we decided to ramp everything down and open the vacuum chamber.

PLAN:

1. ramp down heaters, vent vacuum, open chamber.

2. Try to tape the thermocouples up so that they are further from ground.

3. Try to crimp the bottom of the mass marker tubes, and bend them upwards so they aren't facing ground.

4. Add a dedicated ground to the COIL power supply.

Monday, January 17, 2022, 14:00: HV ramped to 20kV, EZL 10kV, EE, -1500V. Ramping TGHT/TBHT to previous values of 250A/200A.

Monday, January 17, 2022, 16:51 : Back to previous heater values, didn't find any Cs on FC6 so went to Na. Tuned and found the tune the opposite of last time, all voltage wanted to go lower. Found 736pA, maybe better than last time because I tuned quite a bit.

Monday, January 17, 2022, 18:00: Ramping to TGHT 300A, TBHT 230A, where we had sparking problems last time.

Monday, January 17, 2022, 18:17 : So far no sparking issues so I will start to heat up the mass markers. One spark about 4 mins after ramping up, after that maybe 10 sparks/40mins or so. Too many....

Monday, January 17, 2022, 19:20 : Got to 20A on the mass markers, will ramp down now.

Friday, January 28, 2022, 18:49 : Yesterday opened the HV rack to re-start data logging on the thermocouples. This morning ramped everything up and started the heaters. Found the Na current around 250A on the target, but abandoned looking for it because the TGHT heating was causing lots of outgassing, which was causing bias sparks. In addition, there is a weird effect where the Na current spikes, then slowly decreases over the course of an hour or something, to values lower than before the heating. Could this be an indication of some thermal issues, like cold spots where things condense? Or something is drifting. The HV common point on the target is at the mass markers now instead of at the exit of the ion source, but I can't imagine you would see such a large difference. The thermocouples do not change in value during these long slow declines. In light of this, decided to just go up and see what the thermocouples read. Settings were close to what is shown above - bit lower on the HV but magnet the same.

Monday, January 31, 2022, 16:23: Power/sources off. Thermocouple reader off. HV rack open. -AS

New thermocouple setup:

Monday, February 28, 2022, 18:57 : Data logging started. Forgot to set interval, not sure what it is at....

PLAN:

Ramp up coil to 50A, record temperatures

Ramp coil down then ramp target and tube to same values as before, record temperatures.

Ramp coil as before.

Tuesday, March 01, 2022, 14:52: Vacuum @ 1.60e-06T. Waterlines opened - AS

Tuesday, March 01, 2022, 14:54: Vacuum ok.

Turbos stopped Wednesday night. Ready to be uninstalled after venting and water purging.

3rd version of the mass marker target has been installed. This one is further back on the heat shield, and has a longer ceramic piece attached. There are three thermocouples as follows:

Monday, March 21, 2022, 13:55 : Roughing down.

Monday, March 21, 2022, 16:45 : Turbos have been on for a few hours. Starting water.

Monday, March 21, 2022, 17:20 : Only TC1 has to be tested with heating and maybe swapped if it is the wrong way around. Otherwise ready to go.

Thursday, March 24, 2022, 10:51 : Ramping up heaters to test thermocouples.

AS:

Monday, April 04, 2022, 09:10: Power locked out. IG1 & Turbo pumps off. HV top cage removed.

Swapped the old 9pin connectors out and replaced with 2 5-pin connectors, same as on the modules.

See attached for current pin out diagram. Many of the wires are too short to reach the bottom sockets, so wires 2, 8, 9 are not connected in the connector. 4 spots are empty on connector 2 (right).  (6, 7) and (4, 5) are twisted pairs. Unused wires are tapped up out of the way, but we should improve this, the tape may come loose due to heat and then the wires could present an HV risk. (Update: added some wire to hold them in place. Slightly better...)

Need to either extend the wires, or put in new ones. All wires are grounded on the rack.

In addition, there are two screws in each connector which are floating right now. Need to make a connection for them but should be ok if we dont go to really high voltages.

Wiring which was changed to run the mass marker tests has been reverted:

• anode bias cable connected to "B"
• tube negative attached to HV common through "B" to "F" connection

Ready for cathode biased FEBIAD operation.
