It was found that the conversion from voltage to vacuum (Torr) in EPICS is not correct for the XGS-600 controllers in use at the TCS. EPICS did not correspond to local values displayed on the controller. An e-fault has been submitted.

 EPICS conversion updated and corrected by Mike Rowe.

The corelation betwenn the local value on the gauge controllers and the read back valiues in EPICS was compared. Data can be found in a previous  e-log

 The roughing pump for TCS was started at ~3:00 and the turbo's turned on at ~4:00. This is the minimum time for the module to pump down.

Plant Services group (Tony) will contact a service tech on Monday.

Water system will be switched off over the weekend.

Thursday, July 14, 2016, 13:24: Claus from Daikin is on site to troubleshoot.

The VFD driven fan motor has failed. Temporarily blocked air-flow through failed fan to improve air-flow to radiator. A new motor will be ordered (Curtis).

Thursday, July 14, 2016, 15:39: Stopped cooling system for the day

Friday, July 15, 2016, 08:16: Cooling system started

Friday, July 15, 2016, 15:00; Cooling system stopped.

Bevan attempted to start pumping down on TM4 today remotely but there was an issue.  He will report on Monday.

I went into the Target Hall this afternoon while on the phone with Bevan and performed the following:

- Checked the knurled vent valves on the side of each turbo, both were found to be in the tightened position (all the way clockwise)

- Closed the VAT valve between the scroll pump and the nuclear ventilation

Update TH MS project schedule. See attachment 1,2.

Update 2017 winter shut down target hall schedule. See attachments

The 2A2M19 beam profile monitor did not work and was e-faulted. After initial troubleshooting 2 blocks were removed form ITW to inspect the entrance module where the beam monitor is installed. The cable was found not to be connected and was quickly fixed. Blocks reinstalled. The work was done by Maico, Travis and Anders

Ucx#10 has been removed from TM4 and placed in a pail with argon.

Ta#44 has been installed onto TM4 and target heater bolts torqed to 130 in.lbs.

Ucx#6 was installed on TM1 on Wednesday.

Ta#39 was removed.

UCx#30 has been removed from TM#4 and put in a can with argon. 5(10) pin connector had to have guide screws removed to be uninstalled.

UCx#31 P2N installed.

UOx was removed from TM4 yesterday and NiO#1 installed.

Video was taken.

Main stand-off insulators continue to deteriorate.

I connected the CS  vacuum system  to TM4. The CS and TM4 turbo pumps are started. Everything is good so far. The HS line will be pressured with helium tomorrow for leak checking. The CS and TM4 will be vented with Argon on Wednesday morning as planned before moved to ITE.

The UCx#9 target has been revomed from the target module...leg A was broken as suspected.

Ta#42 has been installed. High current connection fasteners torqued to 150 in lbs.

UCx #5 has been removed from TM4. The left oven leg is indeed broken.

Target has been placed in a pail with an argon feed.

UCx#46 removed from TM4 and placed into a pail back-filled with argon. Nothing visually unusual; no issues.

UCx#46 Target handover from TPO 

Target insertion: successful 

Parasitic Install: All Parasitic targets left off target

• Left side In-beam array type parasitic install attempt #1 
  • Parasitic assembly is too thin/studs too tall for the socket nut to fasten onto target. Stud protrudes through the length of socket section, not allowing tool to insert 
  • previously a 3/4 spacer was used to give space for thermal couple to enter 
  • Install of 3/4 spacer was difficult because it does not hold its shape when handled (pivots around 1/2 ad 1/4 portions) 
  • With spacer installed, parasitic assembly is too thick for socket nuts to fasten onto studs. 
    • It may have been possible to back out studs to use, but left off in the interest of time UCx is exposed. 

• Right side In-beam window type parasitic install
  • Similarly to Left side, studs were too short for install, studs could be backed out, but was left off in the interest of time UCx exposed

• PEEK seal parasitic targets were left off as per schedule, and will be leak checked at another date (after tong cable has been repaired) 
  • Order of PEEK seal locations preserved and follows order as seen with target installed (Photo attached)

Target install: successful 

Leak Check: Successful 

Electrical Check: Successful 

• Initially failed due to wiring diagram being different between production wiring diagram and electrical test sheet

Containment box panel closed
