Dear Bruker users,
We are having some problems with the cryoshims in our four year old BRUKER 11.7 T ultrashielded magnet
This is the second time we expect the same problem with this magnet which is connected to a AVANCE DRX-500 console. and as result the lineshape becames so badly degraded that it is not possible anymore to obtain a good lineshape with the normal shimming process.
The solution for this problem is relative expensive, a technician have to come to the lab to recharge the bad cryoshim/s and do a new re-shimming of the magnet.
I wonder if somebody has experienced the same problem with this type of magnet or if there is any suggestion about what could be the origin of this problem.
