Study of microstrip detectors

Single- and double-sided AC-coupled detectors and double-sided DC-coupled detectors read out with the Berkeley SVXD chip are being studied. The authors report on the signal and noise characteristics for typical single channels and the channel-to-channel variations in noise, gain, and pedestal values. Because collider detectors encounter tracks at all angles of incidence, the authors studied the response of the prototypes over a wide range of angles to see whether the cluster size and charge sharing properties of the various detectors are different. For angles at approximately 0 degrees , the resolution of the double-sided detector is 4.5 mu m on the ohmic side and 3.5 mu m for the single-sided AC coupled detector. The signal-to-noise ratio for the double-sided detector is 25:1, while for the single-sided detector it is 38:1.<
