Modeling

• Switch from commercial style to Fermi style
  bayonets (req. by AD/Cryo)
• Reduce overall height
• Finish Nitrogen Tubing
• Rearrange Flanges on Top

4
Reduction in Height

• Currently have 48 (1219 mm) between bottom port
  and helium storage vessel
• What can this be reduced to?

Drawings

• Three weeks to draw and approve?
• Vacuum Vessel and Flanges
• Magnetic Shielding
• 80 K Shield
• He Reservoir

7
Modeling (cont.)

• After vacuum vessel has been sent out, we will
  begin work on the helium plumbing system

8
Heat Exchanger

• Thermek spined tubing has too high of pressure
  drop
• Can use the design from a cryostat at UW-Madison,
  or can order a HXA type heat exchanger as used at
  CERN

Timeline

• Finish Modeling (Sept 30)
• Finish Drawings (Oct 21)
• Bids back, ready to order (Nov 4)
