Helium pressure test on TM4 HS water line at CS is finished. 80psi helium no leak. 

TM4 are vented with argon and disconnected at CS this morning.

TM4 is connected in ITE. All ITE  turbo pumps are started. I will check the pumping down process tomorrow morning. Everything is fine so far.

ITE TP4S was broken down last night . I stopped the ITE pumps and vented station with Argon this morning. Edi and I replaced the broken pump with a new pump. The ITE is under roughing now.

5 Shielding blocks have been transferred from ITW to ITE. ITE  is configured to take proton beam.
 

  TM1 has been disconnected in ITW.

Chad and I  leak checked the TM1 HS line with new target installed. Base leak rate 0.0xe-9 atm.cc/sec. No any response has been found on LD. The line will be pressurized at CS with helium tomorrow.

TM1 is connected in CS. All turbo pumps are started.

Helium pressure test on TM1 HS water line at CS is done. 80psi helium with LD 0.0xE-9 atm.cc/sec. 3 minutes test and no response on LD. The line is leak tight.

Stopped TM1 and CS turbo pumps. Disconnected TM1 at CS. The CS and TM1 are under vacuum and naturally leak up. I will vent it on Wednesday morning.

Removed ITW HS and COIL flow rate monitors installed at the beginning of this year. They were installed on these two circuits for testing.They are broken during last run in ITW due to radioactive field.

TM1 has been connected in ITW.  ITW and TM1 turbo pumps have been started. Water is supplied to TM1 only. Everything is good so far.

TM4 has been disconnected and moved to SHC from ITE. ITE was vented with argon before move.

This morning Chad and I leak checked TM4 HS line with new Ta#44 target installed. I calibrated LD before the check. Before check, the LD base LR 0.0xE-9 atm.cc/sec, base LP 0.0xE-4 torr. Chad sprayed helium on both VCR fittings and did a flush around the target. There is no any response had been found on LD,. The line is good on leak tight. with spray method.  No helium pressure test on the HS line at CS since TM4 was moved back to ITE directly.

TM4 has been reconnected back to ITE. I started all turbo pumps on ITE and TM4. The ITE TP4s was extremely difficult to start. This pump is new, and was replaced before  the last ITE beam time on July. After several times try and starting mode switch, it is started. Its temperature and current draw showed on controller and very good after the start. The current draw on ITE TP1s is  s a little bit high and unstable. I will keep watching on ITE TP1s. I think the ITE TP1s is close to the end of the pump life. Other pumps are good so far.  

TM3 has been connected in CS. All water supplies are bypassed theTM3 on the top of the service cap. TM3 TP2 was difficult to start. It is started finally after couple of time try.The pump runs fine now. 

TM1 was disconnected in ITW this morning. Heat shield circuit is purged.

I started TCS water system this morning to check if the chillers work properly.

TM3 TP2 stopped working this morning at 4:00 AM. I tried to start it but failed. On normal start mode , It could not pass 6K RPM. On soft start mode , the pump cant pass 17KRPM. Talked with Anders, We are not going to replace this pump since we are not going to run this module for a while. I will stopped all   vacumm pumps on CS and TM3 this morning.
