Fault: 14601

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.

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

Ramp coil as before.

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:

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.

No P2N is loaded. Testing the power supplies.

Tuesday, May 03, 2022, 10:07

In the past few days, the ITS has been reconfigured for P2N operation:

•  The two ATTS PS were moved to the ITS rack, one on top of the TGHT and the other instead of the COIL
• AC rewiring was necessary since the breakers were not connected to the wires. Marshall was on it and re-connected
• Ray has configured the ATTS PLC to be compatible with P2N operation in ITS
• The controls cables to the MASTER and SLAVE supplies have been configured: the cables come from the front of the PS rack, so we could close the back and top cage if we wanted. One control cable was connected to the relay to send the proper ENABLE signal only when the ITS vacuum and water flow are OK
• DC cables re-routed for P2N parallel operation:
  MASTER+ = D
  MASTER- = C
  SLAVE+ = E,G 
  SLAVE- = F,H
  TBHT+ = A
  TBHT- = B
