    keyword=Right sieve slit position encoder dead

    The position encoder for the Right Arm sieve slit is dead. It resides inside the collimator box on the front of Q1. This is inside the spectrometer vacuum system. The collimator can be moved, but we have no readback to tell us where it is. The power supply to drive the motor has been turned off.
