Argon venting has started. It will be left to vent over night. 

 The HV conditioning reached a maximum of 44kV today before a spark took out the canbus card. I will attach the data once I have had a chance to format it. 

 During HV conditioning of TM4 with Ta#40 there was a spark at ~43 kV that caused the Bias card to "fry". Dave Morris has been contacted and has said he will replace it tomorrow.

 Once again the 7.5 compressors are tripping due to faults. I believe it is due to over pressure as a result of the chiller fans not coming on. I have contacted ESC.

The special tool made for the RFQ target autopsy has been inserted into the hot cell.

4-40 button head screws have been successfully lossened.

Rob walker has flushed and refilled the primary side of the system (note the water still looks nasty). This morning the primary side of system needed to be bled as there were air pockets. Also TK2 had reached its low point and needed to be topped up.

The pumps have been turned on at ~9:30 this morning. Current values are 6.61 Mohm TCS:DIC1 @19.4 C. HV testing will start momentarily.

 Rob Walker has drained the primary side of the conditioning station. It will be flushed, filled  and chemically treated. It was desired to chemically treat the primary side before before but it took so long that sediment was found (things started to grow).

 The turbo pumps have been turned on and are running

 ESC came today and "repaired" the chiller. There was something wrong with the VFD controller. The were able to get it to start and run correctly again but were not able to recreate the problem. At this point it appears that it has magically disappeared. 

TM4 Ta#40 HS leak check is done at SHC . No leak has been found so far. There will be  a helium pressure test on it at CS.

TM#4 with Ta#40 has been moved from the south hot cell to the conditioning station.

Ta#40 has been installed.

Leak checking and high voltage tomorrow before the move.

TM#4 with SiC#28 has been moved from the south west silo to the south hot cell.

On May 16th 2013 the module was HV conditioned all day. As a result the maximum stable voltage has been increased to about 47kV (~4kV more than last test). A maximum voltage of 49kV was achieved but the module was very unstable. Attached is the data from the testing. Note that occasionally the sparking caused the PS to reset, it was turned back on and the voltage increased back to what it was (or lower) quickly.

TM#3 with SiC#28 (RFQ Target) has been moved from the east target station to the south west silo.

TM#3 with no target or source trays has been moved from the conditioning station to the NE silo.

Manipulator has been sucessfully repaired. Recieved 0.19 mSv. Took Approx. 10-20 minutes

 After discussion with Friedhelm it was decided to continue trying to condition the module today before moving it tomorrow. The voltage was quickly raised until 40 kV where it was left for ~30 minutes. Sparking was minimal. It was then slowly raised to 44.3 kV it held this voltage for ~8 minutes when the current started to climb (remained below 200uA as set as a limit in previous tesing). There was also sparking at this point. This continued for ~2.5 minutes until once again the water resistivity sensor tripped again. It appears that there is a~ 44kV limit on TM3. Attached is the data. I will present all of the data to the group tomorrow showing the results of multiple testing.

 To confirm that the sparking was coming from the module rather than the conditioning station TM3 was grounded and the conditioning station biased. Attached are the results. Highlights include that there was no sparking and the station was able to achieve 60kV (limited by controls from going higher). The current from the raw file has been corrected by the required factor of 5.
