TCS cooling water system was started and tested this Wednesday. Chiller compressor 2 and 3 was in operation cycle twice without issue. TCS:TK2 was refilled to 28 inches. Water system works fine. system was switched off after test.

TM4 has been connected at TCS for HV test. TCS water system and vacuum pumps are switched on.

TM3 is located at TCS and it is pumping down now. TCS water system has been started.  All TCS water lines for TM3 module internal cooling are bypassed and looped at TCS top ground plate. Water only supply to TCS high  current conductors.

I will restart all pumps Monday morning.

The TCS and TM2 are pumping down.

  1683   Monday, January 29, 2018, 06:51 David WangConditioning StationMaintenanceTM1 TCS and TM1 vacuum pumps switched off

TCS and Tm1 vacuum pumps are switched off this morning. TM1 TP1and TP2 work fine during this test period. Tm1 will be moved back to silo this morning.

TM1 IG1 stopped work during the test period. It could be broken. We will only replace this gauge if TM1 is used in ITW again.

  2446   Thursday, May 25, 2023, 13:10 David WangConditioning StationMaintenanceTM2 TCS MP1 is replaced due to poor performace.

TCS MP1 is replaced due to poor performance( system shows unstable and high reading on TCSCG1A and high TP1,TP2 current draw) . The pump is edward 15i scroll pump. Since vacuum group has no same spare pump, i have to use SMP roughing pump SMP:MP1 which is a  same pump to replace it.. After the replacement ,the TCS:CG1A and TP1, TP2 current draw are back to normal. The original TCSMP1 was surveyed. Swipes on intake and exhaust port are 300 counts and 1000counts. RAM contact field measurement are from 0.2 to 0.5 usv/hr. It is stored in TH. We will try to refurbish this pump first and use as for SMP:MP1. If we can not refurbish it, a new 15i pump will be purchased for SMP:MP1.

2023-05-31: Opened pump tip seal chamber and swiped chamber inside. The contamination level :1200 counts on 44-2.  The tip seal and tip seal chamber o ring need to be replaced . Checked gas ballast knob. The O-ring inside knob is in good condition. Checked exhaust port o-ring. it is in good condition. spare part PO will be issued soon.

2023-06-14:Tip seals and o-ring have been replaced on original TCS:MP1. After, it was tested at TCS for 48 hours. The pump is much quiet on operation, and the pump body temperature is mild. The final  inlet pressure this pump could get with TCS PV1 closed is about 23 mtorr.  The result is good. I installed it back to TCS vacuum station and reinstalled SMP:MP1 back to SMP vacuum station.

John Chow and I installed new TCS HV cable and feed through with their mounting panel back to TCS Faraday cage this Tuesday. ECO-4269 has been issued for the new cable feed through and mounting panel.

TCS IG1S  is switched on as well. The reason to start the pump is to prepare a possible extended TM2 conditioning at TCS caused by TH crane issue. TCS:TP1 and TP2 are not switched on for this.

TM4 with SiC#44 installed developed a short TBHT to HV common during its first heating in ITE. Was fine before installation. Now with everything cold TBHT to HVC is 25kOhms. Removed short in electrical room, will rely on short in the module.

the switches and the solenoid are all wire up to 24VDC, when you open either of the little doors the solenoid switches this is also true if there is a power loss. currently the solenoid is powered.
