CryoProbe and Other Accessories

10.3 Helium Cylinders
The next step in the site planning for a CryoProbe accessory involves determining the
location for the helium gas cylinder. A research grade helium cylinder (grade 6.0, 99.9999%)
is supplied by the customer and is connected to the CryoCooling unit. The cylinder must be
outside the 5 Gauss line in a serviceable location (i.e. changing the bottle should not interfere
with nearby magnets). The helium regulator and a special He gas hose are supplied by
Bruker.
Two lengths for the He gas hose line are available (10 m and 20 m).
The helium compressor and helium gas cylinder may be sited in a remote room or in the
same room as the spectrometer as shown in the layout examples.
