Here are some 3D drawing that detail how the Frozen Spin Cryostat is assembled.

Click on each drawing for a larger version.

The Precooling unit.

The dilution unit attached to the end of the precooler. The design is intended to be somewhat modular.

The holding coil is cooled to about 1.5K by conduction with the still (0.75K).
This design utilizes only two heat shields: one at 1K and one at about 20K.

The outer vacuum can, alongside the 5T polarizing magnet (Cryomagnetics, Inc.)
