Lift the magnet
CAUTION: If the CryoProbe is not correctly aligned, its body might touch the op-
tional horizontal pillar braces when the magnet is lifted by about 10 mm onto its
anti-vibration stand. The forces involved can easily break the CryoProbe! Before
the magnet is lifted, there should be a symmetric horizontal clearance of
∫ 5mm between the CryoProbe and any fixed obstruction above its body (see
Figure 3.6.
).
Switch on the air suspension of the magnet and watch the CryoProbe body rise. If
it is about to be jammed against any fixed part, re-align the CryoProbe or lower
the magnet immediately!
Check the magnet alignment
Check the magnet’s vertical position with a level and correct if necessary.
Spinning test
Insert a typical sample into the magnet and check if it can be spun. Remove the
sample after the test.
