Bremsstrahlung is one of the basic photon-matter processes occurring in collisions of electrons with atoms and ions. Bremsstrahlung in electron-atom collisions has been the object of extensive experimental and theoretical studies [1]. These studies focused on the angular dependence of the intensity distribution of the bremsstrahlung, as well as on its linear polarization [2]. Another production...
Experimental results for the radiation emission from ultrarelativistic electrons in targets of 0.03%–5% radiation length is presented. For the thinnest targets, the radiation emission is in accordance with the Bethe-Heitler formulation of bremsstrahlung, the target acting as a single scatterer. In this regime, the radiation intensity is proportional to the thickness. As the thickness increases,...
Echoing classical physics, quantum electrodynamics predicts the release of a spectral continuum electromagnetic radiation upon sudden acceleration charged particles in matter. Despite apparent theoretical success describing sister nuclear processes, known as internal bremsstrahlung, following beta decay and $K$ capture, situation photoejection an electron from inner shell atom, intra-atomic bre...
Some clusters of galaxies in addition to thermal bremsstrahlung (TB), emit detectable diffuse radiation from the intercluster medium (ICM) at radio, EUV and hard x-ray (HXR) ranges. The radio radiation must be due to synchrotron by relativistic electrons, and the inverse Compton (IC) scattering by the cosmic microwave background radiation of the same electrons is the most natural source for the...
Numerous proposals to induce nuclear transformations by intense lasers ~see, e.g., Ref. 1! predicted exceedingly small output of ‘‘nuclear radiation’’ ~positrons, gammaphotons, neutrons, and fission fragments!, even for the laser intensity still out of reach. In fact, efficient production of nuclear radiation was not the subject of those proposals; as a result, optimal choice of processes and t...
Simulations of beam optics and bremsstrahlung for high intensity and brightness channeling radiation
