We have recently had cause to have Bruker replace the gradient coil on our
AMX600 proton probe. The gradient pulse now breaks into numerous, rapidly
damped bursts of 2.4 MHz oscillation. A replacement gradient amplifier
unit had no substantial effect on the oscillations. The source of the
problem seems to be a mismatch between the inductance of the replacement
gradient coil and the output of the gradient amplifier.
Has anyone encountered this problem previously? If so, I would very much
like to obtain information on how the problem was solved.
Thanks very much
Alan
