Leak detector pumped down to base LR1.3xE-9 atm.cc/sec, and BP 8xE-3 torr. All high vacuum gauge readings at CS and TM1 are at low -6 range from 1.2xE-6torr to 4.6x E-6 torr. Applied 80 psi helium  to heat shield circuit for 5minutes and there is no any response on leak detector. The heat shield circuit is leak tight.

Grant and I replaced the conditioning station broken  srcoll pump with a refurbished scroll pump which is supplied by vacuum group. The replaced pump is bagged and waiting for RPG further survey in target hall . The target hall is survey after the job, and everything is fine.

  195   Tuesday, October 09, 2012, 14:53 Bevan MossConditioning StationDevelopmentTM4UCx#5Module Move

TM4 was remote moved from the SCH to the TCS today. This was the first time the module was moved with the framework for the cage in place. The ion gauge on the service cap is closer to the cage than anticipated and as a result the pins for the gauge were sheared off. Discussion as to how to repair the gauge (both short term and long term needs to be had). We will try and rough down the TM tonight, it is not believed the vacuum will be affected.

TM4 heat shield helium pressure test and electrical check were done  at CS  last week. The results are good. NO leak had been found on heat shield circuit.The electrical check is also good.

TM1 TiC #3 target  heat shield  helium pressure check  is done at conditioning station. Applied 80 psi helium to HS circuit for 5 minutes . There is no response had been found on leak detector. The leak detector base LR 0.0x E-9 atm.cc/sec, and BP 0.0xE-4 torr. CS and TM1 vacuum are at low E-6 torr range. The HS circuit is leak tight.

Bevan attempted to start pumping down on TM4 today remotely but there was an issue.  He will report on Monday.

I went into the Target Hall this afternoon while on the phone with Bevan and performed the following:

- Checked the knurled vent valves on the side of each turbo, both were found to be in the tightened position (all the way clockwise)

- Closed the VAT valve between the scroll pump and the nuclear ventilation

Attached are some photos of TM4 in the Conditioning Station after the no-module HV test completion.  Only vacuum services are connected.

the switches and the solenoid are all wire up to 24VDC, when you open either of the little doors the solenoid switches this is also true if there is a power loss. currently the solenoid is powered.

  242   Wednesday, February 06, 2013, 14:34 Bevan MossConditioning StationDevelopmentTM4CS Test Target #140kV All Common w/o Water Test

 Today the module was biased to 40kV in the conditioning station. The current draw was 0uA. Sparking started at 27 kV. I have attached the recording from the strip tool of the vacuum while we were testing. After consulting Pierre if we should take the module to a higher voltage it was decided not to. The purpose of this test we to check the interaction between the module, cover, new cooling line, EE and EINZEL cables. This test was considered a success and although there are no anticipated problems care should be taken when taking the module past 40kV for the first time.

 Hello Ray and Yi

Completed a HV test with the water flowing today.

8.96 Mohm

56.4 PSI across the load

16.5 GPM through the loads

some sparking occurred see attached file.

module was biased with all items tied to common to 40kV. Leakage current was less than 100uA.

This was a very successful test.

  247   Friday, February 22, 2013, 13:13 Bevan MossConditioning StationDevelopmentTM4CS Test Target #1Broken Turbo Pump

 Today while putting the cover on the cord that goes to the controller was bumped. This bent the connector down and caused a vacuum leak. I tried to tighten the bolts in the hope the leak would go away but it did not and I sheared one of the bolts off. David is inquiring with Edi if the pump can be repaired or if it needs to be replaced. The good news is that the interlocks work exactly as planned. Upon detecting a leak they shut the turbos down and closed all of the valves they even beat the turbo controllers for overload.

David believes we can rotate the pump slightly to avoid this problem in the future. Hopefully repairs can start on Monday. 

The conditioning station will be shut down for the weekend.

 Dave Morris and I investigated the Faraday Cup today. It was found to be plumed in the wrong direction (fails in). This is not an issue for the conditioning station as there is nothing down stream from the cup. Dave will change the controls to reflect this.

 TM4 with CS Test Target #1 was moved from the SHC to the Conditioning Station. All went well. The welding cables came a little close to the cage, David will bend them in more in the future.
