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.

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

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.

TM3 has been disconnected at CS. It is vented and ready to move.

Chad and I leak checked HS line on TM1 with ThO#1 target installed. The LD pumped down to base leak rate 0.0xE-9 atm.cc/sec, base leak rate 0.0xE-4 torr. The pumping down process is normal. Chad sprayed helium on both VCR joints (each for 2 seconds) , and he did a flush spray around the target for 5 seconds. No any response had been found on LD during and after the spray( 40seconds waiting time). The target is leak tight.

TM1 has been connected in ITW. All turbo pumps are started. The pumping down on ITW is good so far. The water is supplied to TM1 for HV conditioning.

I found primary vacuum back up pressure ITH CG1, CG2, and CG4A were unusually high this morning. They should be about 10 -20 mtorr after one night pumping, but all of thier reading were 340-350-mtorr. Thease cause the current draw on primary turbo pumps were all over 2.0A(should be about 1.0A). I let Paul closed all BVs on primary side . The pressure dropped quickly to normal range after all BVs were closed. This shows the back up line are good. The problem are from   one of  the connections  on primary BVs. I let Paul opened the BVs one by one,but the problem did not show again. Now ,the current draw on the turbo pumps are back to normal also.

I will keep monitoring the system and take a look on all KF25 clamps on BVs once I have a chance to access to ITW.

CS  vacuum system has been connected to TM3 for control system test(Dave.Morris).

Dan and I transferred 5 shielding blocks from ITE to ITW. The ITW is configured to take proton beam.

I replaced flow wheel and coil on ITW MSP water flow sensor which is located in ITW pit. Before replacement, I checked the signal strength and frequency form e-board on this circuit. The signal was good in 10minutes watching. Still, I replaced them. The flow sensor works fine after replacement. I made a comment  on Isac e-fault system about this issue.

Dan and I replaced flow wheel on ITE HVC2 water flow sensor. The old wheel did rotate smoothly inside its SST case. The new wheel works fine.

I craned down UCx11 target from TH into SHC. Chad was in SHC service area watching on it. The source tray moving jig was installed on the crane for this moving.

Dan and I disconnected TM4 in ITE.

CS roughing pump is started for TM4 and UCX 11 target.
