The SMP assembly was shifted approximately 1.0" north today by pushing it, braced against the south wall, using a 100 Ton capacity air lifting bag supplied by Beamlines Group.  The move was one of the action items identified at the Gate 4A/4B close-out review.  During commissioning of the SMP, TM3 was installed into the vacuum vessel, which required the crane to be all the way at its south limit, so the move is to provide some margin for future use, particularly if TM1 is put in the SMP as the extent of its shielding is slightly larger than the other modules.

One of the air fittings for the lid actuation cylinder on the north side was damaged during the move.  It was replaced and correct functionality of lid actuation was then confirmed.

HALCW MP2 is switched onnow. There is a small amount of air trapped in system. The pump works fine.  Water level and system resistivity will be monitored for a while.

LALCW P5 and P6 are switched on  for cooling HALCW.  HALCW MP2 is in operation now.

Target hall crane does not work properly after TH crane main power is switched off during Christmas time in control room. I switched the main power back this morning. The only movement could be operated is crane rotation. Power is supplied crane. The control  on N-S, E-W and up-down movements do not work. We had the same problem last year. After trouble shooting, It was pointed to a PLC battery issue. Control group changed the battery and reloaded the program. I guess  the battery is drained out very fast for some reason. So, We face the same problem again this year.

Adam checked control room main power supply. I checked in TH crane again. The problem is still there. We can confirm this is the same issue like last year. 

HALCW MP2 is switched on this morning after yesterday cooling tower maintenance. LALCW P5 and P6 pumps are started by isac operator  as well. The system is good so far.

5 shielding blocks are moved out of itw top.

The second module lifting assembly ITA0490 is moved into TH and installed onto TM3 . It will stay with TM3. I adjusted the  CofG on the assembly. It is same to the first lifting assembly we are using now. After adjustment, The installation of assembly on TM3 are smooth. 

ITE water  signal interlock   check is done.  Everything is good. It is a annual check we do in winter shut down time.

 Targeta Ta#49 and Ta#52 have been repackaged anf moved to the mini vault. Ta#49 was taken out of pail number 146 and placed into pail 229. Ta#52 was taken out of pail number 152 and placed into pail 230.

With both stations in operation,ITE dump supply gauge reading is 27 psi. ITW is 20 Psi.  I adjusted ITW dump pressure to 25 psi by changing the return line side pressure relieve valve.

ITE full operation+ ITW no TM: ITE dump pressure 27psi, ITW dump pressure 27psi.

2019-01-30: Water only supply to 2A beam lines only on both side, No TM2 and TM4 in water loop.  ITE dump pressure 27psi, ITW dump pressure 27psi.

 UC#29 in pail 225 was moved to the storage vault, location 6A. Field measured at 22.4 mSv/hr at ~1m. 

Repacked nSiC#1 in SHC and moved it to mini storage vault. Transferred UCx26 and UCx28# from vault to mini-storage. See attachment for vault and mini-storage inventory.

Chad entered the NHC today to tighten set-screws on both slave side manipulators and re-align the West side slave. Work took place using the HC Confined Space Entry procedure. See attached checklist. WP I2020-02-27-4

Using the camera,  Frank and I inspected the broken blades in vacuum duct bending section. We are pretty sure some of  the broken parts are fallen into  bottom of entrance module and vacuum vessel since the broken pars are over on the edge of bending section. The blades rotated at high speed. Basically, They were shoot to the duct opening when they were broken from the pump. Frank and I carefully swiped all broken parts  from the edges  back to center of duct first. Then, We use vacuum cleaner sucked all broken parts out of the entrance module. We can see lots aluminum dust  during the clean up. This kind of aluminum dust also could  fallen down to bottom of module and vessel.  After clean up, We inspected duct with camera. We can see all broken pieces and dust are cleaned out.  The removed broken pieces will be stored with broken pump when the vessel bottom clean up is done.

ITE bias test is done to 48KV. No spark. We can not raise bias above 48KV. It looks like we have a current limit issue on control system when testing above 48KV.  John Cow checked current limit on PS locally. It is set to 8mA which is much higher than the test current. Isac operator issued an e-fault to control group.  

 John Chow did a local test on PS. Everything works fine.The problem is on control system. We have a 48KV voltage limit problem on control system. We decide to end the test now. 48KV is good enough before this year mini-shut down. 

Spent target SiC#39 is removed from SHC to storage vault at 4C in pail #227.The move is successful.  Note:The small aluminum block holding wire on pail lid could be contaminated by SHC manipulator during the lid installation in SHC.

Frank and I did the test.  The emergency exit hatch on roof was opened and closed twice. Everything works fine.

 The entrance module has been moved to the east station to the south hot cell for inspection from the turbo pump explosion.

New IGLIS cables installation is done. Two bundle of new cables are pulled from ITE to electrical room. They are in one PVC conduit. The old cables are not removed yet. I will pull old cables out when new cables are installed onto device in ITE Faraday cage.
