Laser plasma wakefield acceleration (LPWA) is one of most popular novel methods of acceleration. The acceleration process differs significantly for linear LPWA mode and bubble (non-linear) modes. The LPWA has two serous ...

The magnetically insulated transmission line oscillator (MILO) is the crossed field device developed for generation of microwave power at gigawatt level. We have used a numerical simulation method to investigate electromagnetic ...

The plasma lens can carry out sharp focusing of ion beam. At stages of the plasma discharge at which the magnetic field is nonlinear, formation of other configurations of beams is possible. The discharge current distributions ...

The scattering of the plane electromagnetic wave on a spatially extended, fiber-lake target is considered. The fomula for the scattering cross section is obtained using the approximation analogous to Born one in quantum mechanics.

For the initial radii of charged-particle beam in a coaxial magnetic undulator with partially shielded cathode we formulate the equilibrium equations, which enforce the defocusing self-electric field compensation by the ...

In this paper the chain of correlated solitary perturbations of finite amplitude, accelerating ions in the magnetosphere, is investigated.

Results of the theoretical investigations of excitation process of wakefields in semi-infinite dielectric waveguides by finite sequence of nonresonance relativistic bunches are presented. Dependence of wakefield amplitude ...

The ratio of self-focusing due to the compensation of the space charge of bunches in plasma and of focusing by excited plasma wakefield is studied by numerical simulation. It is shown that this ratio is strongly depends ...

The mechanism of focusing of relativistic electron bunches by plasma wakefield, in which all bunches of sequence are focused identically and uniformly, has been proposed and investigated. In this scheme of focusing it is ...

The artificial dielectric model is used in creation of a material with the negative ε and µ and in describing electromagnetic wave interactions with vital tissues. The paper presents the theoretical study of the frequency ...
