Entry  Monday, April 24, 2017, 09:52, David Wang, Conditioning Station, Standard Operation, TM2, , Switch off TCS water system and vacuums 
The TCS bias was turn off before that. The TM2 and TCS are still under vacuum now.

Anders and I found a low frequency issue(13hz only) on TCS TGHT flow sensor when doing TM4 conditioning. By trouble shooting, We found the module water
lines are good. the restriction cause this problem in on TCS supply or return water lines to TGHT.  I switched  TGHT lines with MSP water lines. The
wheel frequency on TGHT is 67.0hz  which is pretty high. Now, MSP is using the original TGHT water  line(flow sensor frequency 13hz). Flow sensors and

Update schedule to show job process in TH. See attachment 1,2.
Entry  Thursday, April 13, 2017, 14:16, David Wang, Crane, Repair, , , TH crane: east side main hoist brake assembly is replaced.  
Gordon Crane technician Tom Kauss finished the replacement of the east side main hoist brake assembly. A new set up is installed. he adjusted gap too
close during first time try. So, the smell appeared when operate the brake. He increased the gap to a proper distance then. It looks like everything works
fine now. Still, The brake need to be tested with 10K lBS load on it. We will do the load test on next Thursday when he come here to replace west side

Found spark signs on TM3's containment on the side of the water blocks. They may be OLD or/and NEW sparking signs, but this in not determined at this
moment. Please see picture: first attachment. First and second attachment show the profiles of water block and HV lines.

Entry  Wednesday, April 12, 2017, 12:51, David Wang, South Hot-Cell, Repair, TM3, , TM3 Ram readings @ SHC 
 We have a ram installed on SHC pole which is 0.5 meter to   module shielding block surface. the readings we got today during TM3 move: 
at containment box center (highest reading): 3.14 msv/hr. 
at bottom  of shielding blocks: 960 usv/hr. 
Entry  Wednesday, April 12, 2017, 09:20, Travis Cave, South Hot-Cell, Repair, TM3, no target, Module move 
 TM#3 is now in the south hot cell.
Entry  Wednesday, April 12, 2017, 07:26, David Wang, Conditioning Station, Standard Operation, TM2, , TM2 and TCS vacuum system has been connected. 
Roughing down overnight. Turbo pumps are started this morning. Everything looks good so far.
Entry  Tuesday, April 11, 2017, 14:06, David Wang, Conditioning Station, Standard Operation, TM4, , SHC, TM2 leak check on HS line. 
Chad and I did leak check on TM1 HS line at SHC. 0.0XE-9 atm.cc/sec.  No leak.

Entry  Monday, April 10, 2017, 11:23, Travis Cave, Conditioning Station, Standard Operation, TM1, no target, Module move 
 TM#1 has been moved from the conditioning station to the north west silo.  There was a slight delay in the move as the limits for the hoist
drum got way out of whack and had to be adjusted.
Entry  Friday, April 07, 2017, 09:53, Travis Cave, Conditioning Station, Maintenance, TM1, no target, Electrical Check and TM1 other checks TM1_elec_chk_no_tgt.PDF
Results of an electrical check on TM#1 with no target attached to it.
 I use this e-log entry for TM1 notes as well  1. TM1 IG1 is a dual filament gauge . Its filament is very close to grid now. It shorted
one time during the pumping down. It still works fine so far . But, we may need to change it if we use this module in TS again.

TM1 inside service cap surface and shielding plug surface are visually inspected yesterday. No rust has been found. I cleaned all rust on top of TM1 
today.  Rust on TM1 silo  top plate are cleaned as well.
Entry  Wednesday, April 05, 2017, 14:13, David Wang, Conditioning Station, Maintenance, TM1, , TM1 and TCS vacuum system are connected together 
I started two turbo-pumps on TM1 and one small TP on TCS. They are work fine.
