Calibration of analog sensors for the alignment of muon chambers in the CMS experiment. M. RIPERT, L. CARAWAY, and M. HOHLMANN.  Florida Inst. of Tech., 150 W. University Blvd. Melbourne, FL 32901. We have developed a semi-automated bench for the calibration of various types of analog position sensors, such as wire-extension and linear-motion potentiometers, and optical photomicrosensors. These sensors will monitor the movement of CMS muon chambers for the purpose of alignment and will be used for critical corrections in the reconstruction of muon tracks. We will discuss our Labview-based control and readout system, calibration procedures, and first calibration results.
