Oral presentation
The Fermilab Accelerator Technology & Science (FAST) facility currently under commissioning couples a high-brightness electron source with a superconducting linear accelerator (linac) and compact storage ring. The infrastructure is expected to provide a testbed for Accelerator Science and Beam Physics. An active area of research regards the production of X-ray and gamma-ray radiation via...

The classical amplitude of the radiation by a charged particle in non-uniform motion is usually derived from the Lienard-Wiechert retarded potential. It can be derived in a simpler way using the concept of classical simulated emission.

Oral presentation
Generic structure of spectra of non-dipole radiation from ultra-relativistic electrons is discussed on two examples:
1. Radiation accompanying double hard scattering of an electron with a time interval T.
2. Passage of an electron through a domain of uniform magnetic field of finite length T.
In both cases, we will assume that electron deflection angles are small compared to unity, but...

A theoretical and phenomenological consideration is given to higher order, strong field effects in electron/laser interactions. A consistent strong field theory is the Furry interaction picture of quantum field theory [1,2]. In this theory, fermions are embedded in the strong laser field and the Volkov wavefunction solutions that result, are exact with respect to the strong field [3,4]. When...

The propagation of a photon is investigating in a constant and uniform electric field at any photon energy. The investigation is based on the polarization operator of a photon in an electromagnetic field [1]. The imaginary part of the polarization tensor eigenvalues gives the partial contribution to the probability of electron-positron pair creation and defines the photon lifetime. The...

We report a novel method for evaluating the energy spectrum of electrons emitting hard x-rays and gamma-rays in undulators and Compton sources. The method takes into account the quantum nature of recoils undergone by the electrons emitting high energy photons. The method is susceptible to evaluate a spectrum of electrons for the whole range of the emission rates per electron-pass through the...

The problem of muon channeling in a standing wave lattice formed by electromagnetic waves is considered. Possible applications of this effect in accelerator physics are discussed.
The charged particles motion in the field of standing electromagnetic wave can undergo the features similar to well-known phenomenon of particles channeling in crystals [1]. While a charged particle enters the...
