We report results of simulation of axial and planar channeling of electrons, positrons and muons in straight [1] and periodically [2, 3] bent Si crystals. The simulations of trajectories of channelled projectiles with accounting for the all-atom interactions have been performed by solution of the classical relativistic equations of motion using newly developed module of the universal MBN...

Experiments have been performed at the Mainz Microtron MAMI to investigate planar electron channeling in bent [1], and in periodically bent silicon single crystals [2-4]. The low emittance electron beam of MAMI providing energies below 0.855 GeV is well suited to prepare a beam with small angular divergence which is mandatory for channeling experiments.
A very important prerequisites for...

The channeling process in periodically bent Si crystals is shown [1-3] to efficiently serve for producing highly monochromatic radiation in a gamma-ray energy spectral range. A short-period small-amplitude bending yields narrow undulator-type spectral peaks in radiation spectrum from multi-GeV electrons and positrons channeling through the crystal. Benchmark theoretical results on the...

An effect analogous to TSF-effect is possible at passing of particles through thin crystals. In this case, nevertheless, not the Bremstrahlung should be suppressed, but the coherent ultrarelativistic electrons radiation. In the last years a possibility is opened to research experimentally this effect, which is connected with the development of the technology of producing ultra thin crystals...
