Abstract
This paper describes the performances of a large volume drift chamber with complete digitization of the output pulses. The electronics used in this te st include wide-band (700 MHz) amplifiers and fast (1 Gsample/s) digitizers . The gas mixture selected for drift chamber operation (80% He-20% CH4) and the signal processing mentioned above allow the measurement of the primary ionization clusters. The improvement in the (wire) impact parameter evalua tion of the primary particle is sizeable. (C) 1999 Elsevier Science B.V. Al l rights reserved.
