The nonlinear theory of relyativistic strophotron is developed. Classical equations of motion are averaged over fast oscillations. The slow motion phase and saturation parameter are found different from usual undulator oscillation parameters. In the strong field approximation the analytical expression of gain is found on higher harmonics of main resonance frequency.

Averaging of Spontaneous Radiation in Relativistic Strophotron

The main resonance frequency is shown to depend on the initial conditions of the electron, and in particular on its initial transversal coordinate xo. This dependence is shown to give rise to a very

Spontaneous Radiation in Relativistic Strophotron

Spectral intensity of spontaneous radiation is calculated in relativistic strophotron. It is shown, that it in the strophotron is given by a superposition of contributions from emission at different

Electron Dynamics in Relativistic Strophotron

. Relativistic strophotron is a system in which fast electrons move along a potential “trough” produced by quadrupole electric lenses. Equations of motion in the strophotron field are investigated

The Gain in RS

The calculated linear gain in relativistic strophotron is averaged over electron distribution. It is shown, that after averaging resonance peaks remain in amplification spectrum. The nonresonant

The emitted energy in RS

The emitted energy of electrons is calculated in relativistic strophotron. It is shown, that it is superposition of amplification at harmonics of main resonance frequency of the system.

Threshold for FELWI operation

It is shown that the possibility to create the free electron laser without inversion (FELWI) has a threshold behavior on the field of intensity of amplified wave. In the collective approach, the

Collective Description in FELWI

Infrared Radiation from Rough Surface

We consider generation of diffusive radiation by a charged particle passing through a random stack of plates in the infrared region. Diffusive radiation originates due to multiple scattering of
