Adsorber
Device inside He Compressor that adsorbs oil and other impurities from the circu-
lated helium gas (He).

Coldhead
Cools down compressed He in a Gifford-McMahon expansion cycle. Its two stag-
es are the primary cooling devices of the CryoCooler.
CryoController
Controls all functions of CryoProbe and CryoPlatform. It communicates with the
spectrometer and is located inside the CryoCooling Unit.
CryoCooler
The CryoCooler cools and circulates the cold He. It consists of the Coldhead in a
cold box unit and a gas circulation unit with valves and gauges. In contrast, the
term ‘CryoCooling Unit’ denotes the whole cabinet including vacuum system etc.
CryoCooling Unit
A cabinet that contains the CryoCooler, the CryoController, a vacuum system,
and the He Transferline. It is labelled ‘CryoPlatform’ because it is the most promi-
nent part of a CryoPlatform.
CryoCoupler
Standardized interface between the He Transferline from the CryoCooling Unit
and the CryoProbe that connects both forward and backward streams of cold He
at once.
CryoPlatform
All parts needed for operating a CryoProbe with a spectrometer, i.e. CryoProbe
Mounting Hardware, CryoCooling Unit, He Compressor, He Transferline, Trans-
ferline Support, VT Interface Box, and optional magnet stand modifications. How-
ever, the HPPR CRP, the optional water chiller, and the He steel-cylinder are not
parts of the CryoPlatform.
CryoPreamp
A cryogenically cooled preamplifier module inside the CryoProbe housing. There
is a frequency-specific preamp module for each channel of a CryoProbe. A Cryo-
Preamp cannot be separated from its CryoProbe. It always requires an additional
external HPPR assembly, the cryo-compatible HPPR CRP.
