Thursday, March 06, 2014, 06:58, David Wang, ITE, Maintenance, TM3, , ITE vacuum and leak check on ITE BL2A window flange.
|
ITE and TM3 Turbo pumps have been started successfully yesterday. The vacuum reading on all ITE high vacuum gauges are at low E-6 range after one night pumping down which are good so far. There is no any sign of leak on BL2A window and the flange seal on ITE side. Yesterday afternoon, Ron , Edi ,and I did a leak check on the ITE BL2A window flange(2aTunnel side). The leak detector was hooked onto BL2A in tunnel. Ron and I supplied helium from TH to the helium test line(located in ITE pit) which we have on ITE BL2A window flange. The helium test line end nozzle is just located under the bottom of the 2A window flange. Edi was in BL2A tunnel checking the leak detector. We supplies 10- 15 psi helium 3 times to the test line. Each time for 10 seconds. The helium flow was checked twice and they were good. The LD base LR was 2.2xE-5 atm.cc/sec, After 70 seconds , The leak rate on LD was increased to 5.3 xE-5 atm.cc/sec. The leak rate reading recovered after 20seconds. There is no obviously conclusion where the leak is. At that moment, Ron said, he and Edi would like to do some further leak check in 2A tunnel,and I went back to my job. |
Friday, March 07, 2014, 12:45, David Wang, ITE, Standard Operation, TM3, , TM3 and ITE air to vacuum leak check and TM3 water lines helium test. 
|
With TM3 located in ITE, All air to vacuum seals on ITE primary and secondary vacuum vessel have been leak checked with leak detector hooked directly on the TM3 service cap.The base LR :00xE-9atm.cc/sec. The ITE IG1 was 1.6xE-6 torr which was good. No leak has been found during the checking.Also, the TM3 water lines(except HS) had been pressurized with 70 psi helium on each for 2 minutes. There was no response during the test. The ITE and TM3 are good on leak checking.See attachment pictures |

|
This Monday morning, Chad and I leak checked heat shielding circuit on TM3 with new target installed. The base LR on LD :0.0xE-9 atm.cc/sec, base pressure 0.0xE-4 torr. Chad sprayed helium twice on the VCR joints. No leak has been found. The circuit will be pressured with helium at CS. |

|
The TiC#4 target that is on TM3 was conditioned to 25kV today with the EINZEL lens at 12.5kV. There was one spark shortly after reaching 25kV that reset the bias PS and another one after the module sat at 25kV for ~30 minutes. Attached is the strip tool data and screen shot. Prior to starting the conditioning the power on the chiller needed to by cycled as the VFD on the fans had tripped due to a recurring inrush problem. |

David W. has installed two SST Proteus flow meters, model OV7006FTA32, on ITW Heat Shield and Coil. The flow meters are connected to a power supply and a data logger in the electrical room.
The Heat Shield flow meter has SN 00278112 and is on the Black wire pairs and connected to CH3 & CH4 on the logger.
The Coil flow meter has SN 00278113 and is on the Green wire pairs and connected to CH1 & CH2 on the logger.
The first channel (CH1, CH3) is temperature in degrees Celcius and the second channel (CH2, CH4) is flow rate in liters per minute.
A camera has been placed on the logger.
Flow rates today (2014-04-04):
HS 8.2 - 8.3 lpm
COIL 8.0 - 8.1 lpm
Calibration sheets
UPDATE 2014-04-11: Corrected HS to CH3 & CH4.

ITE TM3, entrance module, and 2A3 window flange seals have been leak checked this morning after 2 new seals replacement.The LD base leak rate was 0.0xE-9 atm.cc/sec, base pressure was 0.0 XE-4 Torr. I sprayed lots helium around the TM3, entrance module and 2A3 flange seals. No any response had been found on LD during the spraying. All three flanges are sealed perfectly now. |
