Abstract

A second series of monolithic preamplifiers based on epitaxial channel JFETs and intended for calorimetry at hadron colliders has been realized. The employed buried layer process is upgraded, resulting in a lower pinch-off voltage and a reduced power dissipation. Results are presented on noise, dynamic behavior and radiation damage. New versions of the preamplifier are designed for both large capacitance detectors and for low capacitance pre-shower detectors
