TM#4 with Ta#41 has been moved from the south hot cell to the west target station.

I moved 5 shielding blocks from ITW to ITE. The ITW  is configured to take proton beam.

I moved 5 shielding blocks from ITW to block storage area.

The blocks have been removed from the west target station. The fields at the top of the target pit at the railing at waist level is about 80uSv/hr, Turbo pumps are about 805uSv/hr, backing lines for the turbos about a 1mSv/hr and the average field in the area of work down in the pit is about 600 to 750uSv/hr. The proton beam went off at 10:45 on December 2nd, these measurements were done at 09:00 on December 3rd.

Another set of field measurement was done at the west target station. At the top of the west target station at the railing the field ranged from 50 to 70 uSv/hr. The turbo pumps had field of about 650uSv/hr, the area over the dump was about 750uSv/hr, the area over the HV cover and the south side was about 450uSv/hr. These measurements were done at 13:15 on December 3rd.

I disconnected TM4 in ITW .The job took about 20minutes and I got 0.11 msv dose.

TM#4 has been moved from the north west silo to the west target station.

I connected ITW  vacuum system to TM4. TM4 and ITW turbo pumps have been started successfully. The pumping down is good so far.

With TM4 located in ITW, All air to vacuum seals  on ITW primary and secondary vacuum vessels have been leak  checked with leak detector hooked directly onto the TM4 service cap.The base LR :00xE-9atm.cc/sec. The ITW IG1 was 1.16xE-6 torr which was good. No leak has been found during the checking.Also, the TM4 water lines(except HS) had been  pressurized with 70 psi helium on each for 2 minutes. There was no response during the test. The ITW and TM4 are good on leak checking.See attachment pictures

TM#4 has been moved from the west target station to the south hot cell.

TM#4 with Ta#42 has been moved to the west target station.

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.

TM#4 with Ta#42 has been moved from  the west target station to the south hot cell.

TM#1 with UC#9 moved from the conditioning station to west station.

TM1 has been connected to ITW. It is pumping down in ITW with 6 turbo-pumps on.

5 shielding blocks have been transferred from ITE to ITW. ITW is configured to take proton beam. Argon venting system for ITW is ready also.

The TM1 and ITW  were vented with argon gas last night. TM1 had been disconnected in ITW this morning.

  TM1 has been connected in ITW . The new roughing pump replaced on last Friday works good. I started all turbo pumps in ITW. The ITW TP1 controller was broken during the starting time. Dimo and I changed a new controller for ITW TP1 in electrical room. The pumping down is good so far. ITW water supplies to TM1 only.      

Air leak was found at the Solenoid control valve located in the Pre-Separator & DB0 room.  The gasket between the solenoid body and its manifold block was broken, see attached photos. The gasket and solenoid body were replaced. Air was turned back on to IV5 (B/L gate valve) with no apparent air leaks. The gate valve was actuated open & closed from the control room seeing both limits successfully.
