The GEANT 4.9.2 software package is applied for the simulation of primary and Compton scat tered bremsstrahlung spectra. The possibility of restoring primary γ radiation spectra with the energy 0.02-1200 MeV using Compton scattering on secondary scattering targets is studied. The advantages of light targets using are demonstrated. An additional bremsstrahlung contribution from e ± pairs is calculated for high energy γ quanta; the influence of CXR on the form of scattered X ray quantum spectra is estimated. The spec tra which have a multipeak structure are restored. For high energy γ quanta there occurs significant spread of energies in the Compton scattered radiation spectrum, which imposes stringent conditions on collimation and detector resolution capability. The possibility of measuring the bremsstrahlung spectra from a primary target during high angle Compton scattering is estimated.

“…From our experience in studying the orientation effects for a few MeV electrons, it was assumed that the photographs of the distributions of X-ray radiation generated by accelerated electrons penetrating the Si substrate show the effect of channeling the electrons along the atomic planes and axis. At channeling, electrons move for a time along the atomic plane or axis in the bound states of transverse motion [8], emitting X-rays in narrow cone along the direction of their longitudinal motion due to spontaneous transitions between the levels of bound states and Bremsstrahlung born on the nuclei of the atoms of the plane or axis [9]. Therefore, electron channeling manifests itself as a system of narrow bands of intensity additional to a broad cone of ordinary Bremsstrahlung generated by electrons scattered in the crystal in chaotic manner.…”

Experimental investigations aimed at studying the fundamental properties of x-ray generation by relativistic electrons in waveguide structures are presented. Both simple triple-layer W/C/W waveguide and complex waveguide structures such as non-uniform and uniform photonic crystals created on thick Si substrates were used. The W/C/W waveguide effect proved in x-rays distributions as an additional narrow peak inside a wide cone of ordinary Bremsstrahlung. Yield and angular density of the x-rays exited in the waveguide and then emitted from the waveguide channel is much less than that of Bremsstrahlung emitted from whole bulk of the waveguide radiator. But the waveguided x-rays are emitted only from the waveguide channel having very small width. X-ray generation in non-uniform photonic crystal (a multilayer having a channel inside) combines the effect of x-ray generation in the layered substructures of the multilayer (the layered walls of the channel) and waveguide effect for the generated radiation passing the waveguide channel in the guided modes due to both multiple Bragg and multiple full external reflections.

“…This transverse oscillation causes the charge to emit radiation. Andersen [2] and Pantell [3] during the early 80's investigated this paradigm experimentally. Quantum mechanically, the relativistic longitudinal momentum of the particle is orders of magnitude larger than the corresponding lattice momentum; therefore, it may be assumed that the lattice has no impact on the longitudinal motion.…”
