The original HS 45253-23 Had to be replaced due to a leak being discovered during a leak check. Reassembled in 45235-10

However post-TS https://elog.triumf.ca/TIS/Test-Stand/1014 & https://elog.triumf.ca/TIS/Test-Stand/1015, it was discovered there was electrical shorts, components stuck together, including the retainer to the ovens tube. This had to be repaired & rebuilt.

Repairs included opening ITD0542 inner diameter to 11/16"

increasing the slot gap on the HS for the target leg to bottom insulator clearance

Source Cup inner ID opened 0.030" as the short was found to be the tube touching the Cu wall.

Top & bottom insulators were also replaced pre-TS. Checked post TS. They held 540 OL & 1049 OL respectively afterwards.

Run in TS: https://elog.triumf.ca/TIS/Test-Stand/1018
