Subject: Cooler to tank connection 

Attached is a drawing of the first phase (minimal vibration isolation) cryocooler attachment, where the main tank connects via the blue rimmed feedthrough. Boxed/circled components are those that will require custom fabrication:

  1. Copper adaptor from heat station to thermal strap
  2. 5.25" outer diameter 2-153 o-ring connection to conflat adapter (DN75 (4-5/8" outer diameter, 3" tube OD) pictured, but am comparing this with the DN100 (6" OD, 4" tube diameter))
  3. Conflat to ASA o-ring adapter
  4. a + b: Copper adapter from the flat strap connector to the round copper vacuum feedthrough (closeup shown in second figure)

Currently there are only two connections that require viton o-ring rather than conflat connections (cooler to piece 1, piece 3 to HV feedthrough).
