V. Radeka et al., MONOLITHIC JUNCTION FIELD-EFFECT TRANSISTOR CHARGE PREAMPLIFIER FOR CALORIMETRY AT HIGH-LUMINOSITY HADRON COLLIDERS, IEEE transactions on nuclear science, 40(5), 1993, pp. 1321-1324
The outstanding noise and radiation hardness characteristics of epitax
ial-channel junction field-effect transistors (JFET) suggest that a mo
nolithic preamplifier based upon them may be able to meet the strict s
pecifications for calorimetry at high luminosity colliders. Results ob
tained so far with a buried layer planar technology, among them an ent
ire monolithic charge-sensitive preamplifier, are described.
