5 shielding blocks have been transferred from ITE to ITW for next week TM4 move.

This schedule is following Dons schedule on module moves. See attachments for updating.

2015-03-27: Weekly update the schedule. The shut down job is close to the end. See attachment 3, 4.

Chad and I leak checked TM4 HS water line with new Ta#45 target installed at SHC. Leak detector base leak rate 0.0Xe-9 atm.cc/sec, base pressure 0.0Xe-4 torr. Chad sprayed helium twice on each of HS 2 VCR joints.No leak has been found. The joints are leak tight. The helium pressure test  will be done at CS later.

I connected TM4 and CS vacuum system after TM4 move. CS roughing pump was started first this morning. Later, Anders, Bill and I started 3 turbo pumps on TM4 and CS. The pumping down is good so far. The CS vacuum system ion gauges are turned on also.

The helium pressure test on TM4 HS line at conditioning station is done. No leak. I also leak checked all vacuum seals on TM4 service cap. They are all good.

TM4 has been connected at CS which includes high current cables, water lines, EE cable, and Enizel lens cable. The HV cover has been  installed onto the TM4 service cap.The CS water system is started. All water signals are good so far.   Anders will start  HV and heaters conditioning on next Monday.

Updated schedule this morning after last Fridays ISAC facility support group meeting.

Updated schedule on 2015-April -02. See attachments 3,4. The scheduled all shut down jobs are done on time.The TM2 move to SHC will be delayed to May.There will be a new beam running time TH activities schedule (start from April 15) replacing this shut down schedule on next time  weekly update.

TM4 has been disconnected at CS. The CS and TM4 is venting for move. Anders stopped vacuum and water system yesterday.

I replaced ITE tank to module 42 ID X 0.275 o-ring. The o-ring is changed once a year before the first beam time. The flanges was cleaned and the new o-ring was installed. It works fine.

TM4 has been connected in ITE. ITE six turbo-pumps have been started. So far so good.

5 shielding  blocks have been transferred to ITE. The ITE is configured to take proton beam.

See attachments 1, 2 for target hall schedule from 07 April to 26 June 2015. The first TM1 move which is scheduled on 16 April 2015 could be delayed because of SHC operator availability. I will update the schedule once Don confirms the move date with Isaac.

Updated the schedule. The TM1 move has been re-scheduled to Friday, 17 April 2015.    See attachments 3,4.

The TH will be locked during the TM1 conditioning time due to  an interference issue between CS HV cover and a gas analysis valve on top of TM1. A work permit has been issued for the conditioning job because of it.

I did an electrical check on TM1 at CS. The resistance check:A-B 3.918m ohm, A-C 5.905m ohm,A-D 4.070m ohm,B-C5.462m ohm,B-D3.633m ohm. They are very close to the check we did in SHC. The only unusual thing I found during the check is the ohmmeter reading between A and 60 KV common (6.2K )and the Megga reading between them  at 250 V which is 0. I repeated 4 times and always got the same readings. However, after so many times check, the Megga reading between A and 60KV   suddenly went back to normal(300 M at 250V) at the final check.  And,it stays at 300M now.  All other measurements are same as we did at SHC before.         

There is a huge leak on TM1 containment box window. I did a 70 psi helium pressure test on all TM1 water circuits this morning. The LD base leak rate was 0.0XE-9 atm.cc/sec. When applying the 70 psi helium to containment box window circuit, the leak rate on LD jumped to 1XE-4 atm.cc/sec in 5 seconds.I released the helium source right away,t but the conditioning station is full of helium  molecules already, and the leak rate on LD stays at 1xE-5 atm.cc /sec.  The leak on this circuit is huge.    Other water lines are good.        

TM1 has been partially disconnected at CS for tomorrow move. The CS TP1S is still running and will be stopped and disconnected tomorrow morning.

Dan and I vented CS and TM1 with Argon gas before it is moved this morning.

Dan and I replaced ITW target pit o-ring seal(.275DIA X42"ID). It is an annual job before first beam to ITW. The old o-ring was moved and the groove was vacuum cleaned. The new o-ring has been installed properly.

TM1 has been connected in ITW. Five turbo pumps have  been started. The TM1 containment box window line is capped on the service cap and the line is pump town to E-4 torr range.
