Problems of position reconstruction in silicon microstrip detectors

The algorithms for position reconstruction in silicon microstrip detectors are studied, and the signals of a minimum ionizing particle are simulated. The center of gravity distributions of the data events allow the fine tuning of the signal forms and of the strip response functions. In the sensors with floating strips the response function turns out to roughly approximate the response of a triangular function for the size of the signal involved. The simulations are extended to nonorthogonal incidence. In these directions, and in general for all the asymmetric signal distributions, the standard application of the η-algorithm introduces a systematic error. A signal reconstruction theorem gives the way to implement the corrections of this error.
