OBIC analyses of particle detectors are presented. The depletion layer width W of semi‐insulating gallium arsenide Schottky detectors versus biasing has been studied and it is concluded that at high voltages W linearly increases with the applied bias. Furthermore, the electric field distribution in silicon p–i–n detectors has been investigated before and after heavy irradiation and a V‐shaped distribution has been assessed.
