An electron passing through a counter propagated laser flash can interact with a few laser photons with emission a hard photon in each collision event. In contrast with the well-know nonlinear Compton backscattering (CBS) process where an initial electron “absorbs” a few laser photons and emits one hard photon the above mentioned process may be named as multiple CBS process. Physics of such a...

Intense ultra-short hard X-ray pulses can serve as a novel tool for structural analysis of complex systems with unprecedented temporal and spatial resolution. With the simultaneous availability of a high power short-pulse laser system it provides unique opportunities for a number of subsequent research steps at the forefront of relativistic light-matter interactions. At HZDR we demonstrated...

The radiation from a relativistic charged particle uniformly revolving along a non-equatorial orbit about a dielectric ball has been investigated. The results of numerical calculations testify that (a) for definite «resonant» values of the particle revolution frequency, and (b) in case of large values of the permittivity of ball material (strontium titanite) an intensive Cherenkov radiation is...

The report is devoted to the discussion of the nature of Vavilov-Cherenkov effect. This radiation in transparent medium becomes observable under the condition when the phase velocity of its propagating turns out to be less than the velocity of the initial charged particle. The geometry of Vavilov-Cherenkov radiation driven by an electron bunch traveling obliquely in a vicinity of a prismatic...
