M. Menichelli et al., FAST PREAMPLIFIER FOR TIME-OF-FLIGHT SILICON STRIP DETECTORS OPERATING IN THE TEMPERATURE-RANGE FROM 20-DEGREES-C TO -55-DEGREES-C, Nuclear instruments & methods in physics research.

A fast preamplifier for time-of-flight measurements has been construct
ed and operated at low temperature (-55 degrees C). The design criteri
a and performance tests are presented. The measured rise time with a s
ilicon strip detector with a capacitance of 15 pF is 3.2 ns. This prea
mplifier is employed in a cold silicon strip time-of-night apparatus w
hich has a time resolution of 120 +/- 6 ps at -55 degrees C for minimu
m ionizing particles of unitary charge.
