Simulations were performed to calculate beam deflection of planar-channeled protons and carbon ions by bent crystals, in the energy range of a few hundreds of MeV/u. With only weekly relativistic particles, deflection angles may reach 10° and above for particles surviving channeling conditions.

The present work deals with the problem of transition radiation characteristics measurement in the prewave zone. We consider backward millimeter wavelength transition radiation generated by ultrarelativistic electron during its traversal of thin metallic plate in vacuum. In [1] it was shown that the use of large (much larger than effective transverse size L of electron’s coulomb field at...

Parametric X-ray radiation generated by relativistic electrons in crystals and polycrystals with different quality of grain structures is studied experimentally. The obtained results are compared with the existing PXR theories for crystalline [1] and polycrystalline structures [2]. A deviation between the existing theories and measurements is observed for textured polycrystals which can be...

One of the ways to describe diffraction and transition radiation (DR and TR) is the application of the boundary conditions to the solutions of Maxwell equations on the boundary of two media. It becomes evident that the boundary conditions could be satisfied only after addition to the solutions of Maxwell equations with the charge and current of the passing particle the solution of free Maxwell...

Most targets from natural and industrial materials, used for Cerenkov radiation (ChR) generation have a refractive index in millimeter wavelength region n> 1.4. It is often a problem to output the radiation from such cylindrical or planar targets because the angle of incidence of ChR on the outer surface of target is greater than the angle of total internal reflection. In this report we...

In recent years, emission of terahertz (THz) electromagnetic waves attracts essential attention of researchers. Radiation in this frequency region can be used for variety of applications, for example, investigation of biology objects, beam diagnostics in accelerators, etc. One recent idea for producing efficient THz radiation consists in passing of specially prepared electron bunch through a...

The work is held to investigation of alcohol solvent role in the mechanism of electrochemical films formation on the transition metals. Photoelectric polarization data in situ allowed to find that structure and mechanism of the surface layer growth is determined by donor-acceptor interaction between d-metals surface states and dipoles of solvent. They are associated to neutral...
