Anders Mjos wrote:

The conductance check on the electrical check was found to be outside of accepted values for the TBHT at 7.0 mOhm. A successful attempt to reduce the conductance was made by re-tightening the bolts on the TGHT legs in the SHC. Grant operated the manipulator and torqued the bolts to about 1/8 of a turn with the air ratchet. The conductance across the TGHT (A-B) could be improved from 7.0 mOhm to 6.2 mOhm by re-tightening the bolts. The value is still somewhat higher than usual, but was deemed to be acceptable. Measurements attached.

 The full electrical check was done on October 25th 2013. The results are in the attached PDF. The higher value of the conductance was dealt with see Anders Mjos elog entry for those details.

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.

TM#4 with Ta#41 has moved to the south hot cell, the move it self was uneventful but, the fields on the module are extremely high when lowering it down into the south hot cell the module had a maximum field of about 392mSv/hr. The shield plug was also installed remotely as well due to the 12mSv/hr field at the top of the west target station due to shine from the dump.
