Abstract: (Elsevier)
We present the results of an experiment in which a proportional chamber sampled the ionisation loss of each incident relativistic particle some 60 times. The chamber, filled with 80% argon/20% Co 2 was exposed to a beam of pions, protons and electrons at momenta between 25 GeV/ c and 150 GeV/ c at the Fermi National Accelerator Laboratory. The observed pulse height spectra were corrected for systematic effects and compared with new Monte Carlo theoretical calculations discussed in paper I. The agreement is good. The relativistic rise is sufficient to enable individual pions and protons to be distinguished even with the present apparatus. Our results suggest that with a larger device kaons, pions and protons may be separated.- ENERGY LOSS: CHARGED PARTICLE
