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 | M9 | Repair | M9 B1 moved to warm cell |
The M9 B1 was removed from the M9 channel surveyed and moved to the remote handling warm cell for refurbishment.
The warm cell is currently locked. Remote Handling should be contacted if access is needed to B1.
A field map of B1 is attached as a pdf file. |

Keith C Ng | Primary Beamlines | Development | Vault beamline beam position monitor |
The Beam Position Monitor between 1VB1 and 1VM3 has been installed. The indium joints are leak tight, however the V flanges are leaking slightly. The leak is small enough to still be able to run beam.
The Pin drive at the BPM and 1VB1 joint was replaced with a new one. The pin drive that was originally there had a bent screw drive so it was retired. The clamping collars at both joints were reused. |

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. |
