Troubleshooting

Table continued

Indicator

Possible reason

Solution

Performed by

Nitrogen ice in the
helium vessel.

Times between
pumping and
flushing were too
long. Nitrogen
boiled off during
pumping and
remaining nitrogen
got frozen during
flushing.

Warm the magnet coil

with warm helium gas

by using the precooling

tube until the whole coil is

at 90 K or above.

Repeat pumping and

flushing.

Use the dipstick to check
that the helium vessel is
empty (no liquid nitrogen
or frozen nitrogen).

Bruker Service

Transfer of liquid
helium does not
start.

The transportation
dewar is empty.

Refill or replace transporta-
tion dewar.

Bruker Service

The transfer
pressure in the
transportation
dewar is too low.

Increase the transfer
pressure.

Bruker Service

The transportation
dewar is leaky, no
transfer pressure is
built up.

Check the transportation
dewar for leakage.
Re-tighten all connections.

Bruker Service

The siphon or the
helium transfer line
are blocked with
ice.

Check the siphon and
helium transfer line for
blockages. Remove ice with
warm helium gas.
