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

 Further HV testing was completed today from ~2:00 until 3:00. The resistivity of the water was 11.7 - 12.7 Mohm. The EE was turned on to 1500 V and had a leakage current of 1.465 mA with a inline and ballast resister of 20 kohm and 1 Mohm respectively. In addition to this all of the CB were turned on to 500V. The voltage on the source tray with all bias items tied together and the voltage was then raised to 30kV in 5kV steps. It was then raised until 37kV in 1kV step at which point the first spark was detected. Steps were then reduced to 500V until 39.5kV was achieved. Sparking was noticed when stepping up from one voltage to the next and steps were reduced to 100V. At 39.7 kV there were several sparks and the voltage was held for 8 minutes until there had been at least 4 minutes since the last spark. Voltage was increased to 41.2 kV at 292.97 uA when a spark caused the HVCLTBHT paddle wheel flow sensor to trip. Flow was affected but the interlock was tripped due to noise and as a result the BIAS and EE voltage dropped to zero. At this point the required data had been collected and it was decided to shut the station down. RGA scans were taken during the test and are attached. The edited data with graphs is attached in the excel folder. PNG1 was not monitored as it has failed.

 Both the Cooling Package and Vacuum have been turned off in preparation for the module move tomorrow

 During Testing it was noticed that Fault 2 was indicated and one of the compressors would not run. Fault 2 does not indicate what the issue was and during inspection nothing could be detected. It had something to do with TCS:CHILCP3 and possibly CP2. CP1 could still be operated and was controlled manually to keep the temperature in the correct range. This was not required but it does affect the conductivity. The main power switch on the chiller unit was turned on and off and the fault was cleared. As far as I know this indicated either a freeze protect, flow, or refrigerant pressure fault. I will ask for TCS:TS6 and TCS:DIF2 to be added to the archiver so this can be further investigated in the future.

 The lost Binary file. Binary files are no longer used and cause the the tool to crash. The option has not been removed from the strip tool users are just supposed to know not to use it.

 Data has been put into and excel spread sheet

 Today Chad entered the south hot cell on work permit 2013-08-29-3 to repair the leaking heat shield line. The heat shield line was removed from the module and the surfaces cleaned. New C seals and spring were inserted and the line re-attached. During this time Chad also installed the new vacuum gauge. Grant took video of this work and Keith some pictures. The video and pictures can be found on the M: drive (groups) in the RH folder. The total time taken was ~ 25 minutes. The line was then pumped on and the block was sprayed with helium. The pressure and leak rate started at 0.0 x 10^-4 Torr and 4.0 x 10^-8 atm*cc/Sec. When the helium tank was opened there was an immediate response with the leak rate climbing to 2.7 x 10^-7 atm*cc/Sec. It then stabilized at 2.0 x 10^-7 atm*cc/Sec and was sprayed with helium. Response time was ~2 seconds the leak rate climbed to ~2.3 x 10^-5 atm*cc/Sec the pressure also increased to ~3.0 x 10^-3. The leak detector cart was left attached for another 1.5 hours but still was not able to stabilize in the 10^-9atm*cc/Sec range.

 Also of note is that Chad received a full days dose and that when the plastic was surveyed there were ~150 counts found on it.

Today Chad entered hot cell again and removed the HS module side and Junction Block Wiring Harness (module side). In addition to this he blanked off the module side HS line. It took Chad 16 minutes to perform these tasks and he received a dose of 0.20 mSv bringing his total to 0.84 over the last 2 days. After exiting the hot cell Chad completed a leak check on the module side. The line pumped down to the limits of the leak testing cart 0.0x10^-4 Torr and 0.0x10^-9 atm*cc/sec and there was no response. A video of Chad in the hot cell can be found in:

This afternoon was spent surveying the anteroom and receiving teaching from Chad as to how to be a hot cell operator. There was little in the way of contamination ~150 counts near the HC door and ~50 counts on the surrounding floor. The wiring harness has a field of 900 uSv/hr but is suspected most of that is coming from the aluminum steerer bracket. 

In preparation for F-308 loading, three pails were moved from the main storage vault to the mini storage vault. The following pails were moved:

• Pail 270 (C#3)
• Pail 276 (UC#39)
• Pail 231 (UC#41)

Target Index spreadsheet updated, attached.

The spent target assay were finally started or re-started today. Four targets were done today.

June 29 2016 another four targets were done today.

June 30 2016 all targets have assayed and measured. see the attached PDFs for the results.

 The spent target assay was aborted today after the first target was finished due to the very old computer that controls the camera and the vault door effectively died. The vault door had to be closed using the emergency door closing winch which worked so it passed that test.

 All targets in the ISAC Spent Target Vault have been either assayed and had field measurement done on them or just measurement if to hot to assay.

Around 7pm tonight I opened the main valve approximately 1.5 turns on the Argon bottle used for venting ITE, located in the ISAC electrical room. The cylinder pressure gauge increased to about 1500 psi. I adjusted the secondary regulator (pressure relief valve) until it read 2psi. I opened the needle valve in the vent line completely. The pressure on the pressure relief valve dropped slightly and I adjusted it again until it read 2psi. The Argon supply should be ready for venting ITE w/ TM4. The station should be vented around midnight to prepare for TM4 disconnect tomorrow morning. If there are problems with the venting process, an operator should check the pressure on the secondary regulator / pressure relief valve to ensure it is reading 2psi. - Grant Minor

Inspected new high current flexible cables during TM4 disconnection. The new cables and adapters work fine.

 David Wang made E/L checking before module moving to ITW. read attachment pls.

Tm4 has been disconnected in ITW per document 141576. Checklist is done.  HS line is purged.
