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, XTPAGE 17, that TW# B1-375 is broken. |

Keith C Ng | M20 | Repair | M20 Q2 repair notes |
See attached scan for repair notes regarding M20 Q2 during the 2019 winter shutdown. The repair method for M20 Q2 was instigated by Doug Preddy and Beamlines group. Cooling line was blanked off during the 2019 winter shutdown in order to keep the M20 beamline running without removing the magnet and doing a complete repair on the leaking coil. |

Keith C Ng | Primary Beamlines | Standard Operation | lead pig radiation survey |
Surveyed contents of storage flask located at TNF. The lid was lifted off roughly 12" up and a pole monitor was swept over the opening. The fields of the combined items in the flask were 9.84 mSv/h at 12-24". Extrapolated, the field is approximately 3.7 mSv/h at 1/2 m.
The flask contains an indium blank off plate, ISAC beam window and some miscellaneous used water fittings. The ISAC window is probably the largest contributor to the field.
A list of the contents and the dates the were placed into the flask are attached to the top of the flask lid. |

Keith C Ng | Primary Beamlines | Standard Operation | 4V CM1 RH joint install |
2022 Apr 28 to 29:
Installed a new remote handling 4" indium joint for new beamline 4 north section. Issues were encountered in clearance between the downstream steering magnet and the compression collar of the joint. Joint installation itself went smoothly.
The drive screw is a 17mm hex instead of a 5/8". This was noted in the install of the blank off plate in 2016.
See attached pdf report for photos and more description. |
