TM4 has been connected in ITE. All turbo pumps have been started now. The pumping down on TM4 and ITE is good so far. The water interlock check on TM4 is done,and everything is fine. The ITE  IG1 still couldnt be turned on even if we replaced a new TM4  IG1 at CS. The problem is on the connecting cable from ITE to electrical room or gauge controller. I talked with Friedhelm  and vacuum group will be noticed on this problem.

TM#4 with SiC #29 has been moved from the conditioning station to the east target station, move went well.

Spent target Ta#40 has been placed into storage. The target was placed in pail #107 and was put into slot 5A of the vault. It had a field of 224mSv/hr upon removal from the south hot cell. See attached PDF for more details.

to reduce the radioactive shining from  SHC Ta# 40 target.

Bevan and I did a helium pressure test on TM4 HS water circuit at CS. The leak detector is pumped to the bottom scale(E-9 atm.cc/sec and E-4torr). We applied 70 psi helium to the HS circuit for 3 minutes .  No response had been found. I also leak checked IG1 flange which was replaced yesterday. It is  good. We connected the TM4 to CS and put the HV cover on. The water cooling system will be started soon.

Electrical check of TM#4 with SiC#29 attached. Results are pretty much the same as yesterday for the coil to 60kV common, and anode to 60kV common. See attached pdf for details.

3 turbo pumps on TM4 and CS have been started. The pumping down is good so far, The TM4 PNG1 reading is more than 10 times higher than IG1 which is at the same chamber. It could be a controller problem.  Other 3 high vacuum gauges behavior normal.  The TM4 IG1 is replaced today and it works fine now.

TM#4 with SiC#29 has been moved from the south hot cell to the conditioning station move went well.

Electrical check on TM#4 with SiC#29 has been done. The reading of the magnet coil and 60kV common is low at 750 ohms, normally this infinite. Awaiting further instruction on if this is a pass or fail. See attached PDF for the rest of the details.

Results of electrical check on Ta#40 target on TM#4 post beam at the south hot cell

TM#4 with Ta#40 has been moved from the east target station to the south hot cell move went well.

   I have fallen behind on the HV testing that has been completed on TM3. Data can be found on docushare in the TM3 Rev 3 folder files are too large to attach. From the last elog entry the following tests have been completed

July 8 2013 - Long HV conditioning 50kV achieved before sparking caused PS to trip. Was unable to recover to the same voltage

July 9 2013 - Attempted to repeat previous test lost PS at 45kV. Voltage continued to degrade during the day.

July 10 2013 - Max voltage achieve 42.5kV discussed with Friedhelm and decided to run the EINZEL lens at 50% of the BIAS in case this is the source of the sparking

July 10 2013 - Max voltage 40.5kV with EINZEL lens. Communicated with Friedhelm and Lia. It was decided 40kV was good enough. Started developing standard test (see below for testing procedure) for Module so a with and without source tray 

July 12 2013 - Only one spark on route to 40kV. PS tripped after ~10 minutes at 40kV. Near the end of the day there wasn't enough time to repeat test.

July 15 2013 - Test repeated, could not hold 40kV. 39kV held for 1 hour with EINZEL lens off. Sparking was making it difficult to keep on.

July 15 2013 - TM3 was electrically disconnected from the conditioning station. The station ran at 60kV for 1 hour with zero sparks.

July 16 2013 - Test repeated with goal of 39kV intense sparking after 20 minutes caused the PS to trip. Once again the EINZEL lens PS was tripping and eliminated from use to make the test easier. With the failure of this test once again Friedhelm was once again consulted. He advised to stop testing as it appears to be causing damage. There is concern that the module is degrading. Lia has stated this does not affect the source tray and that a source tray will be inserted into TM3 and she accepts responsibility if the module does not hold voltage. 

Standard testing procedure for the bias was as follows. Please note that the EINZEL lens was supposed to follow the BIAS steps at 50%. This procedure was approved by Friedhelm prior to operating. This test was never successfully completed and we will not be able to complete a "apples to apples" test once the source tray is installed.

TM#3 with no target and no source tray has been moved from the conditioning station to the north east silo, move went well.

CS water cooling and vacuum system have been turned off at 10:00 AM this morning.The TM3 will be disconnected and moved to silo tomorrow morning.

Leak checked TM3 without source tray in CS this morning. The CS and TM3 vacuum: IG1(top of the TM3 service cap)4.9x E-7Torr, IG2(diagnostic box  primary)1.9XE-6 Torr. IG1S (secondary vessel)7.9X E-7Torr. The leak detector was at 0.0XE-4 torr and 0.0XE-9 atm.cc/sec level during the leak checked. All water lines quick connector fittings, NPT thread fittings, water cap seals, blue insulator seals, bellow, gauges seals, turbo-pumps, all blanket panels,and TM3 to CS vessel seal have been sprayed with helium and leak checked. No leak has been found. The TM3 is leak tight in CS.

TM4 has been disconnected in ITE. All water lines on TM4 have been purged. ITE is venting now.

5 shielding blocks had been  transferred from ITE to ITW.  The  ITW is configured to take proton beam.

TM3 has been moved from the south hot cell to the conditioning station. David and I completed the move. All went well.

I have inspected the service tray water block and suggest that they SHOULD be cleaned/polished before we install the new source tray.

The water blocks have slight water scalling to the inside of the ID of where the c seals locate.

I have taken two close up  pictures of each water block for reference and to document their current state. They can be found at http://documents.triumf.ca/docushare/dsweb/View/Collection-10841
 

 I  reconnected TM1 to ITW on 02 July.The pumping down is good so far. TM1 water interlock check is good also.
