A CMOS current preamplifier and shaper with 50 Omega line driver for liquid argon preshower

In the field of liquid argon calorimetry for the LHC detector program, a CMOS “current conveyor” preamplifier was developed for a cold preshower. It is an improved version of the ICON circuit which had been formerly designed by the RD2 collaboration. This paper also presents a CMOS linear output buffer, featuring a dynamic range close to ±2 V on a 50 Ω load for a 21 mW power dissipation at 77 K. Furthermore a biquadratic 7 MHz bandpass filter was developed, based on a high speed rail to rail CMOS operational amplifier. It is meant to be the filter placed at the output of the ICON preamplifie

Neutrino detection with a CF4 TPC : the MUNU experiment

The MUNU experiment has been recently built to measure the neutrino magnetic moment at a reactor. Its central part, at the same time target and detector, is a 1 m/sup 3/ TPC filled with 3 bar of CF/sub 4/. This TPC is surrounded by active and passive vetos. The performance of this detector will be described. (21 refs). ector, is a 1 m/sup 3/ TPC filled with 3 bar of CF/sub 4/. This TPC is surrounded by active and passive vetos.
