Studies of performance and resolution of double sided silicon strip detectors

Double-sided silicon strip detectors have been fabricated and tested in a silicon tracking telescope placed in a high-energy muon beam at Fermi National Accelerator Laboratory. The detectors feature AC coupling to front-end electronics and employ two different techniques for isolating n-strips. The CAMEX 64-channel multiplexing amplifier is used for readout. Preliminary results of measurements are reported on pulse heights, signal-to-noise performance, hit resolution, and impedance characteristics of the detector. Measurements of the bias resistance illustrate a mild dependence on bias voltage and, for the field-effect detectors, a strong dependence on the voltage of the readout strips and field strips. The signal-to-noise ratio is determined to be in the range of 10-12, but is expected to increase with improvements to the electronics.<
