TM#4 with the CS Test target has been moved from the conditioning station to the south hot cell. Move went well.

 Roughing started at 12:06. It was believed there was a problem with the compressed air but there was none, TM1 doesn't leak and so you cannot hear that the connection is made.

 Roughing stopped as the module and cover requires modifications that require the vacuum to be opened.

TM#1 with Ta#39 at the conditioning station, has failed its electrical test see attached pdf for details. Also while setting up for the electrical test one of the high powered flexible connectors popped out its crimp and another is working it out its crimp.

TM#1 with Ta#39 had the electrical check done on it again it passed, changes this time were the water lines were purged and it was under a better then roughing vacuum. See the attached pdf for details.

 TM1 started venting at 4:15 pm with Argon. I will leave the valve open over night.

TM#1 with Ta#39 has not passed it electrical check again, while sitting at the conditioning station at air. The readings have not been consistant. See the current PDF for details.

TM#1 with Ta#39 electrical check at the target station see attached PDF (CHK 4).(April 9th 2013) PASSED

TM#1 with Ta#39 electrical check at the target station see attached PDF (CHK 5).(April 10th 2013) PASSED

On April 08th, all water lines in TM1 had been helium pressure tested(70psi) at conditioning station. No leak had been found.

TM#3 with no target has been moved from the south hot cell to the conditioning station. Move went well. The fields around the module was 1.6mSv/hr.

 Both Turbo pumps on TM3 have failed. They were both attempted to start in soft mode. TP2 could only achieve ~19kpm and TP1 ~10kpm. I have turned off the scroll pump and vented through the turbo pumps.

 Turbo Pump 2 has been replaced on TM3. I got a count of 350 on the sleeve of my tank suit.

With the Turbo pump replaced I have started roughing at 10:48

 Both Turbo Pumps are now operational.

 Turbo pumps 1 and 2 both found randomly off, have been restarted

TM3 leak check at conditioning station without target: TM3 all air to vacuum seals have been leak checked . They are all good. Water lines TAR(+-), TUBE(+-), GAS, MSP , COIL2(+-), EE, HS(1,2) , GE,and WINDOW have been helium pressurized to 70 psi for 2 minutes each . No response had been found on leak detector. They are leak tight.. Leak detector BR 0.0xE-9atm.cc/sec, BP 0.0xE-4 torr. TM3 and CS vacuum: PNG15.2xE-6 torr, IG1 8.8xE-7 torr,IG2 2.8xE-6torr, IG1S 1.3xE-6 torr.      

 Cooling Package was started at 9:25 this morning inlet conductivity is 0.08 Mohm at 22.9C. Resistance reached 5.33 Mohm by 11:30

 The flow meter on the primary side (TCS:DIF2) of the conditioning station is broken. I investigated and there is flow, the gauge is not fouled, and the PLC does read back when current supplied. The gauge is also reciving 24V but the output is 0V and 0mA. I will contact ESC and the supplier.

 A HV test was conducted yesterday on TM3. There was no target and all items were tied to common or ground. The conductivity of the water ranged from 7.1 to 7.5 Mohm. 40kV @ ~600uA without continuous sparking was achieved. The Strip tool was run but something went wrong with the export and the vacuum gauge data is missing. I have attached the file for reference and the pulled data from the achiver (only logs every 300 seconds). RGA scans were taken periodically during the test nothing unexpected was measured but we also do not know what normal looks like. The RGA application is available at http://www.thinksrs.com/downloads/soft.htm. Other items of note include significant sparks disrupts the communication between the computer and the RGA, the PNG1 gauge and its controller, and TP2 local readout screen. 

This morning the Einzel Lens was tested on TM3 as the intention is to reuse this piece of equipment. The EL was able to achieve 39.9kV at ~1.35mA before a major spark happened and the power supply turned off. Also during testing the penning gauge suddenly shot up after a spark, it did not recover and had been acting strange in previous test, it was decided to ignore its value and continue testing but it should be replaced in the future. When I went to save the strip tool data I tried to save it as SDDS binary data out of curiosity and the tool crashed, it turns out this is on old feature and doesn't work anymore. A file was created but I cannot recover any of the data. If I do manage to do so I will will attach it later. Attached is the RGA and Archiver data. 

Other items of note:

Voltage was increased in 1000V increments until ~32kV when it started to have sparks. Increases were then reduced to 500V until 38kV when it sparked and further reduced to 100V increments where it worked until 39.9kV

There is a inline and ballast resistor on the EL circuit values of each respectively are 145Kohm and 200 Mohm
