Refilled TCS:TK2 from 11" to 28.8 ".

I reconnected the entrance module back to the ITE station. All diagnostic cables, turbo- pump, air lines, water lines on ITE entrance module and BL2A3 window are connected back.

ITE entrance module is reconnected in ITE.

TM4 has been reconnected back to ITE. I started all turbo pumps on ITE and TM4. The ITE TP4s was extremely difficult to start. This pump is new, and was replaced before  the last ITE beam time on July. After several times try and starting mode switch, it is started. Its temperature and current draw showed on controller and very good after the start. The current draw on ITE TP1s is  s a little bit high and unstable. I will keep watching on ITE TP1s. I think the ITE TP1s is close to the end of the pump life. Other pumps are good so far.  

I reconnected TM3 in ITE. All turbo pumps have been started. The water supply to TM3 only in ITE. The HV keys are back to electrical room.

Containment box has been removed and water block jig installed.

TCS  cooling polyurethane lines have been re-routed to solve to HV sparking issue on old configuration between lines and bais plate.  New re-routed system is tested to 70KV without spark. No leak has been found on new lines after the test.

ECO 4369, drawings and models IRH1715, IRH1716 have been issued and released for this job. Drawings and Models are located in PDM-ISAC1 -TCS polyurethane water lines re-route folder.

 David and I re-connect Entrance module at ITE after the monitor been replaced at SHC. 

The were issues with both left and right master ratcheting;

- the left handle was getting stuck in a close position when there was a higher ratcheting tension added

- the right ratcheting was not tightening preventing proper use of the manipulator

Chad and myself were able to identify a missing set screw for the tong cable.

Once this was added the issue with the left master ratcheting seems to be solved.

Lubricant was added to the left master ratchet and this seems to solve this problem as well.

There was also an observation of missing set screws on the spare manipulator for attaching the wrist to the ratcheting handle, which will need to be ordered and attached.

TM4 in conditioning station with no source tray, extraction electrode set to HV bias. Brought up to 30kV over the weekend by ISAC ops with no issues.

BIAS=30kV

EL=15kV

IG1=9.4e-7T

Monday, June 10, 2019, 08:21 : At 32.4kV on bias, EL at 15kV, bias sparked to EL. Every bump of 100V on bias is accompanied by a small vacuum jump and often by a small current increase from ~60uA to 120uA.

* Conditioning station read back and set values are off by 2kV but archive values show this has always been the case. Which to trust? *

Monday, June 10, 2019, 08:54 : Spark while sitting at 38kV on bias, 19kV on EL. Seems to be a spark to EL.  Sitting at 38kV for ~10mins

Monday, June 10, 2019, 09:32 : Sat at 40kV for ~10mins or so, bumping up again.

Monday, June 10, 2019, 09:38 : Spark to EL while sitting at BIAS / EL = 42kV / 20.5kV

Monday, June 10, 2019, 13:57 : Ramped to BIAS / EL = 43 / 21.2. No problems other than what seems to be the usual conditioning station stuff.

 Monday, June 10, 2019, 14:17  : Couple sparks on the way to 48kV, seems to be to the EL.

Monday, June 10, 2019, 14:36 : Up to BIAS/EL = 51/25.5 with no big problems. Will stay here for a couple mins

Ramped down the bias so David could remove the HV cover and lock out the target hall.

Ramped back up to BIAS / EL = 50kV / 26kV quickly with no sparks.

Monday, June 10, 2019, 15:35 : BIAS / EL = 52kV / 26kV

Monday, June 10, 2019, 15:45 : BIAS / EL = 54kV / 28.5kV. It seems that keeping the EL at 1/2 the bias voltage is right on the edge of what is acceptable - the HV seems to be sparking to the EL instead of to ground (either that or the EM interference from the sparks it producing a reaction in the EL...) I will run the EL higher and see if that helps.

Monday, June 10, 2019, 15:57 : Sat at 54kV for > 10mins, will continue up

Monday, June 10, 2019, 16:11 : At BIAS / EL = 55.8kV / 29kV got some sparks, some to EL and some to ground. Back at 55kV.

Monday, June 10, 2019, 16:24 : Sitting at 56kV for a couple mins

Monday, June 10, 2019, 16:37 : Sitting at 56.3kV bias, a spark tripped off the IG1S, which tripped the turbo and shut down all the HV. Back to zero!

Measurement taken at 14:25. IG2 at ~7.7E-6 T

 Following the helium pressure test Don attempted to connect to the RGA via the network. He was unable to do so. This scan was desired so a pre and post water scan could be compared to indicate if there was any leaking. It has been decided to carry on as the HV and HP tests are of greater importance. Don will continue to investigate the RGA. Travis inspected from the conditioning station roof and determined that the RGA is getting power.

 The communications chip has been replaced. The electronics box has been grounded (see attached pdf).

 The locations (ports) for the RGA and CG1S was swapped today by Anders and Isaac to provide clearance for the North Hot Cell ventilation. Attached photos show old and new locations.

Major portions of the RFQ target have now been sucessfully dismantled. More minor dismantling with conclude this afternoon.

Tested RF from RF driver into new IGLIS wires at ITE. Used 5V, 1MHz (2MHz setting because of internal halving issue).

As expected there was a very slight mismatch visible (original cable ~ 68 Ohms, new cable ~ 53 Ohms).

The matching resistor will be changed and it will be retested.

R U coil line removal started at 11:30. Water block jig installed and coil line disconnected from module.

Thursday June 12th two 55 gal drums filled with waste from the SHC. 1 drum with metal waste, 1 with mostly air hoses. Pre-filter also changed and scissor table hydraulic lines inspected. looks ok.

Thursday, June 6 two 55 gal drums of waste were also removed. 1 of metal and one of compess. (plastic, tank suits etc)
