Abstract

An experimental setup is described which is designed to study radiation effects due to the channeling of high energy charged particles in a single crystal. The setup consists of drift chambers and scintillation counters and operates on an electron-positron beam line at the Superkhov accelerator. The design of the setup makes it possible to study in detail spontaneous radiation effects due to the channeling of high energy charged particles in a single crystal. The setup allows one to reconstruct particle trajectories with high precision, to determine the momentum of secondary particles, to identify their types, and to measure the angles and energies of emitted photons. The total amount of material along the beam direction is approximately 5×10 −4 radiation lengths. The setup operates on-line with an EC-1040 computer and is provided with an advanced program package.
