Sažetak

A survey of known methods of analyzing linear polarization of high-energy photons is presented. The methods of pair photoproduction in single crystals and in amorphous targets are briefly discussed. The method of measurement of photon linear polarization using azimuthal asymmetry of the recoil electrons from pair photoproduction on electron (triplet photoproduction process) is considered in details. The optimum region of kinematic parameters of emitted particles in which analyzing power increases is discussed. Possibility of using CLAS for the measurement of linear photon polarization by analyzing the recoil-electron distribution in triplet photoproduction process (when shielding magnet is turned off) is considered.
