Some Helpful Terms
Throughout this document, certain terms will be repeatedly used. This is their meaning.

Bucket Dewar
(used with CFG-SL, CFG-PS, CFG-PS4, CFG-SJ, CFG-SD, CFG-PD, or CFG-PD4 assemblies)

PopTop Capsule
(contains the crystal or detector element, preamplifier, and HV filter)
Electronic Shroud
(electrical shield for preamplifier and HV filter)


EndCap
(vacuum enclosure for the detector element)
Cryostat
(vacuum enclosure that provides a path to cool the detector)
Dewar
(vacuum container for LN2)

Dipstick
Having a cryostat that "dips" into the LN2 dewar (refers to the CFG-PV-1, CFG-PV4, CFG-PH-2, CFG-PH4, CFG-SV, and CFG-SH). Other cryostats/dewars are integral.
