Possible Hadron Identification in a Beam Formed by a Bent Single Crystal

Possible hadron identification in a beam formed by a bent single crystal is shown, based on the synchrotron part of the radiation spectrum of channeling particles. Identification efficiency and beam intensity are estimated for UNK. I" At higher energies, traditional methods of measuring the fast charged particle 7-factor e.g., Cherenkov counters are not effective, so alternative methods are of great interest. Kumakhov1 has proposed the use of channeling radiation for identification of electrons and positrons. This method, however, is not effective for heavier particles. In the present paper we will show the possibility of using the synchrotron part of the radiation spectrum of particles, channeling in a bent single crystal, for their identification. In the radiation spectrum of particles, channeling in a bent single crystal, a soft syn chrotron part appears,2 which leads to a significant increase in the number of photons emitted per unit length. This can be illustrated in harmonic approximation, comparing the characteristics of the soft synchrotron radiation and the hard channeling radiation parts of spectrum. Radiation intensity is defined by the mean square of the radius of the charged particle trajectory curvature. The power emitted per unit length4 is shown by I = e#
