Przedwzmacniacz ładunkowy do testowania prototypów detektorów krzemowych dla detektora LumiCal liniowego akceleratora TESLA

Abstract

The LumiCal calorimeter is one of the proposed detector for measurements of the events produced at low angles in high energy e+ e- collisions at TESLA linear collider. 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.
