Abstract

An experimental method of determining the active region thickness of Si planar detector was used. The method based on the dependence the depletion layer thickness from voltage applied to the detector (U = 0:::60 V ). The electron energy loss spectra emitted by 90Sr 􀀀90 Y in silicon planar detector were measured. The relative values of most probable energy loss of electrons were de ned for different thickness of detector. The planar detector was considered as a parallel-plate capacitor. The static (capacity) and dynamic (the detection efficiency and the energy deposit) characteristics had a root dependence on voltage.
