ESC came today and "repaired" the chiller. There was something wrong with the VFD controller. The were able to get it to start and run correctly again but were not able to recreate the problem. At this point it appears that it has magically disappeared. 

 Rob Walker has drained the primary side of the conditioning station. It will be flushed, filled  and chemically treated. It was desired to chemically treat the primary side before before but it took so long that sediment was found (things started to grow).

Rob walker has flushed and refilled the primary side of the system (note the water still looks nasty). This morning the primary side of system needed to be bled as there were air pockets. Also TK2 had reached its low point and needed to be topped up.

The special tool made for the RFQ target autopsy has been inserted into the hot cell.

4-40 button head screws have been successfully lossened.

 Once again the 7.5 compressors are tripping due to faults. I believe it is due to over pressure as a result of the chiller fans not coming on. I have contacted ESC.

 During HV conditioning of TM4 with Ta#40 there was a spark at ~43 kV that caused the Bias card to "fry". Dave Morris has been contacted and has said he will replace it tomorrow.

Dan an I  transferred 5 shielding blocks from ITW to ITE. The ITE is configured to take proton beam.

ESC was called out again to inspect the chiller as it was showing the same problem as before. This time when started one fan came on (this is not what happened last time) but the fan controlled by the VFD did not. It was eventually traced to a relay that has been replaced. The system was tested as best it could without a load and appears to be working. It will be difficult to tell until a heat load is in place if the fix has solved everything. 

Dan and I  disconnected TM1 in ITW.

The spent source tray for TM#3 has been removed from the south hot cell and well be placed in the the hot cell ante room. To sit till maintenance day to be moved over to the vault storage tunnels.

TM3 Rev 2 source tray/extraction column insertion into its storage was completed yesterday and it was then removed from the hot cell and put into the anteroom until June 25th when it will be moved into the vault tunnel.

The Box did have 10000 counts of contamination "all over" it. It has recieved inital decontamination and is down to 1000 counts.

the warm cell mock-up has been inserted into the warm cell and final preparation for the remote test are being made.

The testing of the mock-up and tooling has commenced.

Source tray mock-up has been driven into the mock-up and the first two water block connections have been made; the first with the torque limiting 
T-handle tool and the second with the torque limiting air rachet attachment. Both seem to work well, although achieving the required torque with the manipulators proved to be near the limit of the manipulator.

All water block connections on the mock-up have bben achieved. It is now ready for leak checking.

The front half of the water block jig proved extremely difficult to remove.

Ten targets have been assayed or had field measurements(they were too hot to ship but were assayed the last time an assay was done) done on them  over the past two days. Of those that have been assayed we have total of ten shippable targets. See the attached PDF for the latest details of the storage vault.

The Mock-up has been leak tested after the remote connection of the water blocks and is leak tight!

Thanks everybody who contributed to its success.

Chad and I leak checked the TM1 UCx target heat shield at SHC. No leak has been found so far.

The polishing/cleaning tool prototype is now finished and appers to work great.

Thanks to Dan and Maico for the great job making my design a reality.

Tm3 Rev.2 source tary has been transfered to the vault tunnel storage.
