Results on particle identification obtained measuring the primary ionization in a drift chamber operating in a mixture He 80%-CH4, 20% at normal conditions are presented. The data, collected at CERN (PS T9 beam), indicate that the cluster-counting technique allows a substantial improvement with respect to the more traditional measurements. pi/K separation of similar or equal to 3.6 sigma at 4 GeV was obtained over the entire volume of the chamber: 144 (3 x 3) cm(2) cells with an average tracks path length of 120 cm.

Abstract
Results on particle identification obtained measuring the primary ionization in a drift chamber operating in a mixture He 80%-CH4, 20% at normal conditions are presented. The data, collected at CERN (PS T9 beam), indicate that the cluster-counting technique allows a substantial improvement with respect to the more traditional measurements. pi/K separation of similar or equal to 3.6 sigma at 4 GeV was obtained over the entire volume of the chamber: 144 (3 x 3) cm(2) cells with an average tracks path length of 120 cm.
