Double-sided silicon charge correlation study: matching multiple track hits

Double-sided microstripe silicon detectors with analog charge readout offer the possibility of correlating the hits seen on the two sides by matching the cluster charges, providing the signal to noise ratio is sufficiently high. We make a study of this matching from actual beam test data of tracks incident upon two Micron DC-coupled microstripe detectors. A simple algorithm, or simple cuts, are used to match the double-sided charges. Results as a function of the number of simultaneous tracks incident and of the signal to noise (from 15:1 to 30:1) are given. We find that charge correlations should be helpful in reducing the N2 combinatorics usually operative in track finding, matching and fitting.
