Friday, January 23, 2015, 15:21, Keith C Ng, Primary Beamlines, Maintenance, 1VQ4 joint section (WR #2686)
|
1VQ4 & 1VQ6 beamtube was installed by UCN group. RH provisonally installed aluminum indium carrier ring with no indium into joint space with clamping
collar and pin drive. Joint is currently connected but not vacuum tight. Joint will be sealed with indium at a later date, tbd.

Wednesday, January 14, 2015, 11:00, Keith C Ng, Primary Beamlines, Maintenance, 1VQ4 & 1VQ6 beamtube removal (WR #2686)
|
Disconnected and removed beam tube from 1VQ4, 5, 6.
- Q6 end had transition end removed with pin drive driven into the retracted position and left behind but indium joint was still intact. |
|
Thursday, March 31, 2016, 15:32, Keith C Ng, Primary Beamlines, Development, 1VM3 to 1VQ4 joint.
|
Re-installed indium vacuum joint for 1VQ4, routing installation. R. Kuramoto sprayed silicone grease on to the threads and bushings on pin drive. Drove
down tapererd pins and stopped 1/16" short of old marker markings. RK. Commented on the drive screw bending under load, reversed drive 1/2 turn
to relieve the stress on the screw. |

Tuesday, January 23, 2018, 15:44, Keith C Ng, Primary Beamlines, Repair, 1AQ15 insulator repair
|
Assisted beamlines in replacing 2 insulators on 1A Q15 magnet. #10 and #14 insulators were found to be leaking at the ceramic, where the stainless steel
fitting joins the insulator. They were both replaced. During re-installation of the #10 ceramic, the VCR coil termination broke off the coil end and a
new one with updated design (see TBP0379) had to be soldered back in its place. The original SS fittings are deemed to have problems in their construction |

Tuesday, April 16, 2019, 11:19, Ron Kuramoto, Primary Beamlines, Repair, 1AQ14 B/L Flange Broken Thermocouple
|
On March 7,2019 the Thermocouple (TC) cable which monitors the temperature of the 1AQ14 B/L vacuum joint was broken when the iron shield block (Triumf Dwg
D-3237 aka M8 Tongue block) was restored on the east of the T2 Monolyth. See attached photos. This TC (Omega #KTSS-116U-144) is attached to the 1AQ14
Indium ring seal (Triumf Ref Dwg TBP0372D) and should be replaced the next time this B/L joint is serviced.
The Controls Group has noted on the CCSC2, |
