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. |
