High-Energy Charged Particles Separation by Means of a Cascade of Multiwire Proportional Chambers

Abstract The energy losses of charged particles traversing 30 proportional chambers are measured simultaneously. The relativistic rise of ionization is investigated in several gases. A maximum increase of 45% is observed in a mixture of argon-propane, where Landau theory predicts an increase of 78%. The application of these measurements for particle separation is discussed.
