Abstract :
We present a study that shows that charge collection efficiency in silicon microstrip detectors depends on the geometry of the p-stop used to isolate the strips on the Ohmic side. Detector signals for four kinds of p-stops were studied using a laser test stand. We propose an optimal p-stop geometry which realizes acceptable charge collection efficiency as well as low interstrip capacitance and low noise
