The detector will be equipped with silicon sensors interspersed between tungsten plates of absorber. In this paper we present the design of the charge sensitive preamplifier for testing the prototypes of silicon detectors. The detailed preamplifier diagram, tests of linearity and noise measurements are shown.polReport
