falls below the cold tip rather than when the dewar is empty. One solution for this problem is to use a cooling rod
extender such as the ORTEC Model CRE-1, which adds up 4 inches of cold tip to the cryostat.

3.1. ASSEMBLING THE SYSTEM
1) Before installation, you may wish to assemble the the spacers, damping materials, MÖBIUS, and
detector/cryostat assembly beside the shield to make preliminary height estimates, cryostat and shield
height adjustments, etc. Otherwise, place the MÖBIUS under the shield first with no spacers under it
2) Holding the detector/cryostat assembly by the preamplifier shroud or under the detector capsule base, lower
the cooling rod through the bottom of the shield — feeding the detector cabling through first — and through
the fill collar into the dewar.
CAUTION Keep the cabling and connectors from being pinched, kinked, deformed, or otherwise
damaged as they and the cooling rod pass through the bottom of the shield.
