Entry  Tuesday, October 17, 2017, 10:56, Travis Cave, South Hot-Cell, Standard Operation, TM4, UC#21, Module move 
 TM#4 with UC#21 has been moved from the east target station to the south hot cell.
Entry  Friday, October 13, 2017, 11:14, Keith C Ng, Assembly/Bench Test, Standard Operation, , , source tray alignment/build 20171013_sourcetray_P1030815.JPG20171013_sourcetray_P1030816.JPG20171013_sourcetray_P1030817.JPG20171013_sourcetray_P1030818.JPG
Source tray is complete for brazing, gas line bracket is currently missing but can be made in parallel with tube bending operations.
Source tray water lines to be fabricated according to ITA6144 drawing set.
- Alignment between target mounting plate and steerer cone is holding within .002"
Entry  Thursday, October 12, 2017, 08:48, Travis Cave, Spent Target Vault, Standard Operation, , , Field measurements of the old source trays 
 Field measurements were taken of the old source trays. The old TM#2 source tray had a minimum field value of 0.50 mSv/hr and a maximum of 1.18
mSv/hr through 360 deg of rotation. The box was rotated around three times and put back in the vault. TM#1 old source tray was also removed and measured
as well the field values for it were a minimum of 0.52 mSv/hr and a maximum of 1.15 mSv/hr through 360 deg of rotation. The box was rotated around three

Entry  Tuesday, October 10, 2017, 10:45, David Wang, Conditioning Station, Repair, , , Re-route TCS water lines. 8x
TCS  cooling polyurethane lines have been re-routed to solve to HV sparking issue on old configuration between lines and bais plate.  New re-routed
system is tested to 70KV without spark. No leak has been found on new lines after the test.
ECO 4369, drawings and models IRH1715, IRH1716 have been issued and released for this job. Drawings and Models are located in PDM-ISAC1 -TCS polyurethane
Entry  Tuesday, October 10, 2017, 10:38, David Wang, ITW, Standard Operation, , , 5 shielding blocks have been transferred from ITE to ITW .

Entry  Friday, October 06, 2017, 11:21, Isaac Earle, North Hot-Cell, Development, , , ISAC-1 active sump drain pipe modified IMG_0513.jpgIMG_0516.jpgIMG_0517.jpg
The 4" PVC drain line in the ISAC-1 active sump was modified so that the drain pipe terminates below the low level water line of the automatic pump-out
system.  This will prevent backflow of sump gasses into the SHC, NHC, or TCS space if the air pressure in any of those rooms are lower than the sump
air pressure.  The details of the modification were specified by Mechanical Services Group, and the work was done by Paul Jensen.  This system
Entry  Friday, October 06, 2017, 11:12, Isaac Earle, North Hot-Cell, Development, , , NHC module port shield block and TCS vessel shield block installed IMG_0472.jpgIMG_0476.jpgIMG_0479.jpgIMG_0481.jpgIMG_0486.jpg
 The NHC module port shield block (IRH1645) and the TCS vessel shield block (IRH1646) were installed yesterday in the target hall according to assembly
drawing IRH1652.  No issues were encountered during installation.  Vacuum was pulled on the TCS and a leak check was performed on the shield:
no leaks found.
