Glossary
CryoProbe Installation BRUKER 85 (93)
He steel-cylinder
Standard helium gas steel-cylinder (50 L) for the initial fill of the CryoProbe Sys-
tem and for flushing the closed-loop He cycle before each cool-down.
He Transferline
Isolated tube through which the cold He from the CryoCooling Unit flows to the
CryoProbe. The He Transferline is part of the CryoCooling Unit and cannot be de-
tached from the cabinet. It goes in parallel with the vacuum bellows.
HPPR CRP
Cryo-compatible preamplifier assembly located close to the magnet that is a stack
of frequency-specific preamplifier modules, a cover module, and a base plate. To-
gether with the CryoPreamp inside the CryoProbe, the HPPR CRP forms the
NMR preamplifier system. Although it looks very similar to a conventional HPPR,
its components are modified for interacting with both a CryoProbe or a conven-
tional probe. When operating with a CryoProbe, the HPPR CRP performs the RF
filtering in the transmitter pathway, selects the received signal, handles the probe
tuning, and supplies the CryoProbe electronics. An HPPR CRP can be used with
conventional probes just like a conventional HPPR.
HPPRtool
Software tool on the spectrometer workstation Unix/NT level that interacts with all
HPPR types.
Magnet stand pillar braces
Horizontal metal braces that connect the anti-vibration stands of certain B
RUKER/
S
PECTROSPIN magnets. Two braces at the magnet front must be replaced by
cranked ones to enlarge the gap for introducing the CryoProbe.
Mounting Hardware
Special assembly that is attached to the magnet bottom to hold the CryoProbe in
position.
PIC
Probe Identification and Control system that transmits probe-specific data to the
spectrometer.
Pneumatic gas
Usually compressed air or nitrogen gas for the operation of the pneumatic valves
inside the CryoCooling Unit.
Protection Cap
A white plastic cap to protect the CryoProbe sample cavity against dirt during
transport, testing, or storage.
Q factor
The quality factor Q is a measure of the efficiency of reactive devices such as in-
ductors, capacitors, or resonant circuits.
