All turbo pumps are started. 

The tCS will be vented soon for TM2 move later this week.

Preparation on TM2 move from TCS to SHC.

 The TCS will be vented soon for TM2 move.

TCS will be vented tomorrow morning for TM2 moving.

Here is the change in the TCS vacuum after heaters were turned off earlier today:

2:20 pm readings

TCS:IG1 (service cap) 9.3 x 10^{^-7} Torr

TCS:IG2 (diagnostics box) 5.71 x 10^{^-6} Torr

TCS:IG1S (secondary vacuum) 4.0 x 10^{^-6} Torr

7:17 pm readings

TCS:IG1 (service cap) 8.69 x 10^{^-7} Torr

TCS:IG2 (diagnostics box) 5.0 x 10^{^-6} Torr

TCS:IG1S (secondary vacuum) 3.38 x 10^{^-6} Torr

Anders started TCS turbo-pumps yesterday. The TCS and TM4 pumping down is good so far. I started TCS water pumps this morning for TCS water flow check.

2017-05-17 morning:  Stopped the water pumps. The field around the TM4 is high because of spent target in SHC. The water flow measurement will be delayed to this Friday.

TCS and TM3 all vacuum pumps are started. Everything is fine.

I changed TCS tank top flange seal(o-ring 42.00"ID X 0.275" DIA) this morning before TM2 was moved to TCS.

Argon venting is started

A steel plate  is covered on TCS. TCS roughing pump  is started now. The TCS will be pumping down during mini-shut down.

TCS has been migrated to ISAC controls. Access is possible on a per user basis from isacepics1.triumf.ca

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.

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.

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.
