They work fine. Current draw on all pumps are normal. I asked operator to switch on IG1 , IG1S and PNG4.

See attachment. Everything looks good.

 TM#4 with the P to N target has been moved from the south hot cell to the east target station.

 TM#4 has been moved from the silo to the south hot cell.

 The east entrance module has been moved from the south hot cell back to the east target station.

The broken pieces in ITE entrance vacuum pit are vacuumed out.  At SHC, There are 4 pieces on module collimator block top,  wiring scanner top. Chad removed them out at SHC. Electrical check at module top is done by diagnostics group. Everything works fine.

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.

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

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

TM2 was moved from SHC to SMP yesterday.  The move is successful. TM2 is located at SMP. There is no hot target on module so SMP vacuum is not started.

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.

 Electrical check result is fine.  See attachment.

Frank and I removed TM2 from SMP to SHC. The move is successful.

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. 

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.

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

TM2 in SMP with old SiC #39 target on it. SMP vacuum pump is started.

 TM#2 with SiC#39 has been moved from the east station to the smp.

TM4 has been moved from TCS to SW silo. The move is fine.

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.
