MONOCHROMATIC HARD RADIATION SOURCE ON BASE OF 70-MEV RACE TRACK MICROTRON

Creation possibility of monochromatic hard γ-radiation source on base of the high quality accelerator like 70-MeV Race Track Microtron [1] is considered. Quality of accelerated beam permits to utilize it to elaborate a source of hard γ-photons. One of most effective mechanism for applying here is coherent bremsstrahlung (CBR) of electrons in a crystalline target. In particular using of diamond and silicon crystalline target allows to generate the polarized photons with energy up to 30-50 MeV. Estimations predict the CBR intensity in this photon energy region can at more than two times surpass over incoherent radiation one. To increase CBR photon yield, the possibility of special scheme use with multiple crossing of crystal target by electrons is analyzed. In the similar scheme the yield of monochromatic radiation can rise up an order
