On 8March2016, under W/P C2016-03-08-2, 4VQ3 was lifted out of BL4V with the vault orbit crane where it was first weighed then lifted onto the
RH flat deck rail dolly. It was then moved into the RH basement where it was surveyed before lifting it up onto the Red wagon cart in the RH loading
bay. It was then pulled to the Meson Hall loading bay by fork lift where and then over the Cycloton vault to the top of the E-Hall roof beams under |

On 14March2016, 4VQ1&Q2 were removed from BL4V and lowered into the Vault basement B3 level where they were stored in the south west corner
on their respective wood pallets. The hot ends of both magnets were place against the west wall. 4VQ2 was lifted out first and moved temporarily
downstream where it was separated from its magnet stand. Q2 was then craned into the basement where it was tipped 45o to lay on the flat side |

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.

Old #7 coil fitting removed, replaced and re-brazed today by M Good. Insulators ready to go back on to magnet coils to be pressure checked.
Image P1020013.JPG shows #7 coil fitting before removal. Heat shielding in the form of small aluminum sheets were installed to protect the magnet
and electrical wiring. |

Reinstalled ceramic insulators #6 7 8 to Q1 magnet by C Ballard. #6 and 8 went on with no issues. The copper tubing on insulator #7 had to be bent to
match the new position of the re-brazed #7 fitting. This may have been due to the removal of the inner and outer conductors (the two copper plates that
clamp the two coils together) during yesterdays repair which shifted the position of the coil. See photos. |
