Solenoid Magnet Cryostat

• Working concept based on 106 mm long solenoid
  magnet (100 mm coil length).
• Single support post
• heat load to 4 K lt 0.2 W.
• Cryostat length 180 mm.
• HTS leads not yet integrated into design.
• Helium header pipe orientation undefined, shown
  on top for this concept.

Helium line connections

• Main helium line will use Conoseal flanges with
  metal seals (same style as in the Tevatron,
  different size)
• Cooldown line and LN2 lines will be the same
  flanges as the 2? and LN2 in the Tevatron (metal
  seals).
• Vacuum flange will be either a V-band style like
  the Tevatron or a ISO LF banded-clamp, both use
  o-rings.
