50 (107) BRUKER CryoProbe User Manual
Standard procedures
It is impossible to remove the CryoProbe from the magnet while it is connected to
the He Transferline. There are geometrical restrictions and the danger of bending
the CryoProbe tube with the large lever of the He Transferline.
Table 4.11. Remove the CryoProbe
step action
r.1 Make sure that the warm-up of the CryoProbe has been completed
(see "Warm-up" on page 49
).
All connections on the probe should stay in place during the warm-up.
Leave the probe as it is until it reaches room temperature (max. 2 h).
r.2 When W
ARM and UNPLUG are lit: Disconnect all cables and tubes from
the CryoProbe front and bottom.
r.3 Detach the He Transferline from the Transferline Support: undo the
four black screws and lift them off. Leave the He Transferline mobile
but supported such that no forces can act on the CryoProbe when the
magnet air suspension is lowered later on.
r.4 Insert the Vacuum Plug into the CryoProbe bottom by pushing up the
black handle of the Vacuum adapter. It should move easily at the begin-
ning, but needs a little more force on the last cm when the actual seal is
made (Figure 4.13.
).
r.5 Detach the vacuum bellows from the Vacuum Adapter.
r.6 Separate the handle of the Vacuum Adapter from the Vacuum Plug by
turning it counter-clockwise at least ten turns. It should move out
slowly when leaving the thread of the vacuum plug.
If in doubt, proceed with the next step. The CryoProbe’s vacuum cham-
ber is not damaged when subjected to air.
r.7 Remove the Vacuum Adapter.
