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. |

Thursday, April 25, 2019, 11:13, 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. |
