Аннотация

The processes of generation of coherent diffraction radiation (CDR) by a short electron bunch of 45-MeV electron accelerator and its Thomson scattering on one of the subsequent bunches have been simulated. Backward CDR is emitted when electron bunch with population Ne and length σ passes in the vicinity of a conducting target along the direction of specular reflection. In the wavelength region λ≥πσ all electrons in a bunch emit coherently and CDR intensity becomes proportional to the square of a bunch population Ne. In order to increase concentration of CDR in the interaction point we propose to use two semi-paraboloidal targets for generation of stimulated forward and backward CDR and its focusing. We simulated CDR spectral-angular distribution in the interaction point and showed that maximal overlapping of CDR pulse and subsequent electron bunch may be achieved for double focal distance between concave targets coinciding with distance between bunches. In this case one may obtain hard radiation in forward direction for the photon energy range ℏω∼8γ2ℏc/σ due to Thomson scattering with an yield of hard photons proportional to N e 3 The efficiency of considered schemes for obtaining of THz radiation and soft X-ray radiation (ℏω∼÷100eV) with duration σ/c≤ps is estimated.
