HPGe Detector, Part I: Repair » HPGe_vacuum_port

I brazed a QF-25 flange onto a piece of 1/4″ SS flex hose, which was epoxied with Hysol 1C into a 1/4″ hole carefully drilled into the back of the Dewar. Dewars these days contain special multilayer insulation materials, so it is important to drill slowly and carefully to not cause damage.
