Entry  Friday, January 24, 2014, 14:10, Travis Cave, Cyclotron, Standard Operation, Copper blockers 

The copper blockers have been removed from the cyclotron and placed into the coffins.

Entry  Wednesday, January 29, 2014, 15:08, Bevan Moss, Cyclotron, Standard Operation, Shielding and Port Hole Covers 

 The Shielding and the Port Hole Covers have all been installed. No issues with the installation have caused any problems. This orbit, radial, and vertical read back continues to be an issue.

Entry  Thursday, January 30, 2014, 13:47, Travis Cave, Cyclotron, Standard Operation, shields 

All shields, pothole covers, and ladders have been installed into the cyclotron.

Entry  Friday, January 31, 2014, 10:07, Travis Cave, Cyclotron, Standard Operation, 2C removal 

2C has been successfully removed from the cyclotron and is now currently sitting in the B2 level of the RH building. A tank access was needed to feel the stuck QDL.

2C has been installed into the cyclotron.

Entry  Friday, February 21, 2014, 11:05, Bevan Moss, Cyclotron, Standard Operation, Old Monitor Box Removed, New installed 7x

 One of the beam spill monitor boxes was removed and placed into a lead coffin. The fields around the coffin prior to the monitor being placed in were 145 uSv/hr just above the box and 33.5 uSv/hr inside of it. A swipe was taken inside the box at this time and a count of zero was found. The tray for the monitor box was then placed into the coffin and the monitor removed from the cyclotrons. The field above the coffin with the monitor box was 1.0 Sv/hr. Safety hinted that it may be possible to put this in the decay storage tunnel. The copper block was then returned to the coffin. The fields above the the coffin were now 9 Sv/hr. The lid was returned to the coffin and returned to it storage place. The new monitor box was then installed into the Cyclotron. The box only hung up on the pins once and there was some slight difficulties unlatching. From previous experience once fully unlatched a slight tap in the latch direction seems to allow it to release easier.  Overall the installation was considered very smooth.

During the electrical test the was no contact.  To help investigate further the Montitor box was removed from the Cyclotron. It was found to have zero counts. The issue is believed to have to do with the fit of the box but confirmation of the writing harness continuity needs to be completed. This will continue on Monday.
