    keyword=Target: ladder motion problem

    After fixing the oven RTD, we took an NMR measurement in preparation for taking beam. When we moved the target to the He-3 Cell position, we were out of our position by 1mm (readback was 39.46cm instead of 39.36cm).

    In an attempt to clear the problem we sent the target to the "home" position. The reason that this was done is that there is a microswitch at that position and all positions are measured from the home position.

    After returning home, we moved back to the He-3 Cell position. This time our position was off by .5mm (39.41cm). This was okay by Bogdan, so we are running with the target in this position.
