The LVDT driver broke on Wednesday 24th of July.

With Terrence

While we were doing noise hunting on Wednesday morning 24th of July the LDVT driver broke.

While having the AA filter off we changed the power cable by an identical one. When turning the AA filter back on the whole rack went off for an instant and then it came back on, with the exception of the LVDT driver. We tried to turn the driver on but after a few seconds it turned off by itself. Tomura-san suggested this is a ground problem.

We changed the driver on Thursday 25th of July.
