Final assembly and alignment of TM2 optics tray continued today. Front section is "aligned".

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.

TM2 optics tray build is continuing. Going well. Hope to have assembly and alignment finished by Friday.

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.

TM2 optics tray is complete.

Master alignment tray: 0 up/down, 0 left/right

Optics tray: Front 0 up/down, 0 left/right. Middle 0 up/down, 0 left/right. Back 0 up/down, 0 left right.

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.

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.

Weekly target hall schedule update.2015-04-20

weekly target hall schedule update 2015-04-27 attachments 3,4.

The MK4 optics tray prepared for TM2 (as per ITA6082) had an undersized bore for the banana plug, making insertion of the plug extremely difficult / impossible.

Reference stores parts were collected to check the fit:  male plug 3-4/01152 and female jack 1-6/1201.  The size of the female jack was checked with a #21 drill at .159".

The bore on the optics tray was drilled out dry using the #21 drill to the same depth as the original blind hole, by Maico and Dan McDonald.  Chips were carefully collected in a rag, and the hole was blown out with compressed air.

The fit was checked to be snug but possible, using the male plug and the Remote Handling ultem base (ref ITA6023).

Redlines and photos are attached.

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.         

Changed by Dave Morris. 

New value is 1E-5 T (old value was 7.09E-5 T)

On drawing ITA6008 for the Encole 0.5" ceramic standoffs there is a note to match pairs of ceramics to within +/-0.001". This step was missed on the current build of TM2 source tray (ceramics were not measured).

Measured the lengths of the rest of the ceramic standoffs in inventory and they range from 0.5035" to 0.4950" in length. The ceramics have been sorted by length and grouped into bags.

The water blocks soldered to the TM2 cooling lines (see Ref. Assy. ITA6144) were inspected.

See attached inspection reports and drawings.

It was found that only 18% of the seal groove diameters and 55% of the depths were in spec.

The source tray must be tested on the test stand with c-seals to ensure that these blocks will seal properly on the module.

The new TBHT and TGHT power supplies were brough up to high current; 350 A and 420 A respectively. The TGHT power supply was limited by PLC to 420 A. The resistance calculated for both the TBHT and TGHT copper lines from the electrical services room to the ITW pit was 1.35 mOhm. See attached spreadsheet for details.

Dave Morris has been contacted to correct the current limit for the TGHT supply to 600 A.

Containment box has been removed in preparation for wire replacement.

Target Hall Scheduled Activities  April 07 - June 26  2015 update.      2015-05-01. All TH scheduled jobs are finished on time this week.

Caled cyclotron ops to open P23 and confirmed penthouse valve open.

Filled up TK2 to 21 in water leve.

Old wiring was removed yesterday, new wiring run thru the vacuum chase. Old IMG gauge removed today, new cable trays installed and wires installed into cable trays.
