Experimental stand for investigation of electron channeling into crystals

In the Lab. for Experimental Physics of Almaty State Univ. the works are carrying out for creation of the automated complex (stand) for study electron channeling phenomenon and properties of Kumakhov gamma-radiation. The complex one can be divide on 5 subsystems: 1) electron source on the base of Ehlektronika-type linear accelerator; 2) subsystem for forming and transporting of electron beams up to crystal; 3) goniometer subsystem on the ground of goniometer of high precision with five degrees of freedom; 4) registration beta- and gamma- detectors; 5) control and measuring subsystem. Impulse accelerator EhLU-6 type is the electron source, the energy of electrons is from 4 up to 7 MeV, mean current is equal to 600 μA, impulse duration is equal to 4 μs, frequency of following is equal to 200 Hz. Number of unique devices has been created during the design and realization of different units and subsystems of the experimental stand. Its are distributing chamber from monolithic titanium block, collimator of particles with very low angular divergence, precision goniometer of high accuracy with five degrees of freedom, registration system for soft gamma radiation which can be used in different fields of science and engineering
