Description

A beam of polarized γ-quanta is produced and its polarization degree is measured. The experiment is conducted using an electron beam of the Serpukhov accelerator at the 'Kaskad' facility. 28 GeV energy electrons are recorded in a proportional chamber after which they enter a 15 mm thickness silicon crystal. After passing the second proportional chamber the electrons get into complete absorption spectrometer where their energy is measured, and the emitted gamma quanta get to 30 mm thickness silicon crystal. E+e--pair coordinates are measured in the third proportional chamber. Gamma-quantum polarization value of 0.3±0.1 is obtained. 1 ref.; 1 fig
