Update schedule weekly. See attachment 1,2,3.

A meeting was held on May 4, 2016 to determine the scope of the North Hot Cell project.  The following was agreed upon by those in attendance:

The NHC will be a designated target change hot cell.  It will be capable of performing all routine target operations (target removal/installation, leak check, electrical check, video inspection, post irradiation examination, target waste packaging and removal) using the same method currently used in the south hot cell.  Provisions will be included for the ability to perform target waste separation in the future unless a significant obstacle is encountered in which case the meeting attendees will be consulted.  Target waste separation involves separating the internal target heater from the target heat shield, then combining multiple target heaters in a single F-308 shipment.  Neither an inert gas atmosphere nor a double-door waste transfer system will be part of the NHC scope.

The following people were in attendance:  Bob Laxdal, Anders Mjos, Don Jackson, Joe Mildenberger, Friedhelm Ames, Alex Gottberg, Grant Minor, Yasmine Saboui, Peter Kunz

The following people were invited, but were unable to attend:  Chad Fisher, Pierre Bricault

The project will begin immediately, with Isaac Earle as the project leader.  The first steps will be to submit a Project Initiation Sheet, then to write and release the Requirements Specification document.

TM#2 was moved to the SW Silo from the Conditioning Station. TM#3 was from from the NW Silo to the Conditioning Station.

  I switched off TCS and TM2 vacuum pumps. The TM2 will be disconnected at TCS today and moved to silo on next Monday.

Anders and I finished the most part of TM2 water lines helium pressure test yesterday.I list the system parameters and test result as below:

TCS  IG1: 9.8XE-8 torr,  TCS IG2: 9.6Xe-7 torr, TCS IG1S: 3.5XE-9 torr, TCS CG1A: 10 m torr

Helium pressure: 70 psi. Test time: 5 minutes for each individual circuit.  1 hour for all  lines together test.

 Leak detector base leak rate:0.0 X E -9 atm.cc/sec, base pressure 0.0X E-4 torr. LD was always restored or closely restored to the bottom  scale after each individual test.

The HS and Window lines will be tested later with new target installed and  window line gaskets restored.

 TCS water system worked fine overnight. I turned off TCS water system at 6:16 AM this morning. Start of purging TM2 water lines for helium pressure test again this morning.

2016-4-28 7:58AM. Disconnected TM2 water lines at TCS. Purged them with compression air each for 5 minutes. 

The following water circuits in TM2 are connected at TCS and running with water now : target oven+ - ( one circuit), tube heater+ -( one circuit), coil1 and 2(one circuit), MSP, and EE. The HS and window are open circuits now so they can not be supplied with water.  During the check before we knew HS and window circuit were close to perfectly sealed. So, The test result should not be affected without them

The TCS water pumps are started at 8:28 AM. All TCS high vacuum gauge readings are getting slight better after that.

Post MS project and Excel    target hall schedule for beam schedule 130 see attachments 1,2

Update TH schedule 130 with TM3 jobs involved in.see attachments 4,5.

2016-04-29.  Weekly update schedule according to changes. See attachments 6,7.

Weekly update.This is the last update on 2016 winter shut down schedule. The new TH schedule for beam130  will be posted weekly after this. All jobs in winter shut down schedule were finished on time.

Anders reported a possible air leak on TM2 and TCS by watching RGA  this morning. I found the quick connector on F terminal on the top of the module is leaking air. It is only used as "X" terminal for Febiad without  water. So, it should be blind capped instead of installing a quick connector. It was installed with a  blind cap before. I borrowed it for leak check on coil lines at SHC, but forgot to put it back right away. Instead, I put a quick connector on it later. This caused the problem. Anyway The TCS need to be vented , and a blind cap  will be installed on the F terminal.

2014-04-18, 9:24AM, I changed the quick connector with a blind cap on F terminal. the rough pump is started now.

The ITW is configured to take proton beam.

 Thursday, April 14, 2016, 07:50: RGA on

Friday, April 15, 2016, 08:09 : Ratio between water and air is higher than normal (indicating possible air leak). See attachment. 3.5 more H2O than N2.  (Ratio in TM3 Nov 2015 was 82:1)

A leak was found on the o-ring between the module flange and TCS. This could be fixed by cleaning the o-ring and sealing surface. The Window line is not closed and was accidentally pressurized with He on April 25

Tuesday, April 26, 2016, 08:47: David started the water package.

Wednesday, April 27, 2016, 08:15: Switched off chiller / water cooling.

Wednesday, April 27, 2016, 14:41: Switched chiller / water cooling back on.

TCS is under roughing now.

2016-04-14, Started TCS and TM2 turbo-pumps yesterday afternoon. Overnight pumping down is fine.

TCS is under roughing now.

TM#2 has been moved from the south west silo to the conditioning station.

Tm4 has been connected in ITE. The ITE and TM4 is under roughing now. ITE

Turbo-pumps have been started. Everything is fine.

TM#4 with Ta#47 has been moved from the conditioning station to the east target station.

The TM4 is still under vacuum at TCS. It will be vented tomorrow morning.

I disconnected TM4 vacuum system at TCS.

The spent UC#14 target has been moved into the ISAC spent target vault. See the attached PDF for the details.

70 psi helium , 2 minutes. Base leak rate 0.0x E-9 atm.cc/sec. base pressure 0.0XE-4 torr. no response on LD.The line is good.
