Particle identification using the angular distribution of transition X-radiation quanta
Abstract
Theoretical calculations are presented pertaining to the optimization of transition-radiation detectors for the identification of hadrons at gamma not greater than approximately 0.001. An electron detector has been developed which simultaneously determines the emission angle of transition-radiation photons and measures energy release in the gas of the drift chamber. Experimental results are presented from the CERN supersynchrotron installation for electron and hadron beam energies of 15-140 GeV. A substantial improvement in the efficiency of particle identification was obtained at gamma approximately equal to 0.001.
