摘要：

The response functions of Si surface barrier detectors (depletion depth: 2 mm, active area: 200 mm2) to monoenergetic electrons and positrons have been measured in the energy range 0.8-3.5 MeV at the Giessen electron linear accelerator. Lower peak-to-total ratios were observed in the positron response functions compared to electrons. The measured response functions were compared with Monte Carlo simulations enabling a separation of the individual contributions to the response function such as: total energy loss, backscattering, transmission, bremsstrahlung emission. A parametrization of the response function for electrons is given, which allows a reliable approximation of the response function in the investigated energy range.
