Abstract :
Charged particle (π-K) separation in the momentum range 0.5-0.7 GeV/c using a new method of shape analysis of the signal from a liquid krypton (LKr) ionization chamber has been experimentally studied. The detector has been exposed to pions and protons at the T11 test beam at the CERN PS. The shape of the preamplifier output signal was recorded by a waveform digitizer, then it was doubly “differentiated” in order to obtain few dE/dχ measurements inside a 2 cm LKr gap. Results on particle separation at three different energies are presented.
