Sumario: | The possibility to convert the photon beam linear polarization into circularone at photon energies of hundreds GeV with the use of crystals is considered.The energy and orientation dependencies of refractive indexes are investigatedin case of diamond, silicon and germanium crystal targets. To maximize thevalues for figure of merit, the corresponding crystal optimal orientationangles and thickness are found. The degree of circular polarization andintensity of photon beam are estimated and possibility of experimentalrealization is discussed. |
