Intense Beams of Polarized and Nearly Monochromatic Photons from Coherent Bremsstrahlung
نویسنده
چکیده
One of the major considerations in planning photoproduction experiments is the choice of technique for generating the photon beam. Several possibilities exist, chieey Compton-backscattered laser beams, tagged and untagged bremsstrahlung, and coherent bremsstrahlung from a crystal. In a coherent bremsstrahlung beam, collimation can be used to suppress the incoherent component and to narrow the energy spread of the coherent photon spectrum, producing beams with monochromatic peaks of only 1-2% r.m.s. width and high ux and polarization. The potential and limitations of this technique for use in photoproduction experiments at 8GeV and above are discussed in this report.

Bremsstrahlung in weak charged current polarized lepton - nucleon deep inelastic scattering
The processes of lepton-nucleon scattering, including ones with both polarized beams, at high energy provide relevant information about interaction and particles structure, allowing to analyze nucleon spin structure. As energy and experimental accuracy rise, necessity to improve Born cross sections and polarized asymmetries with higher order radiative corrections becomes substantial. In this re...

Coherent bremsstrahlung (CBS) is a specified type of radiation at colliders with short bunches. In the present paper we calculate the main characteristics of CBS for the BEPC collider. At this collider dN γ ∼ 3 · 10 8 dE γ /E γ photons of CBS will be emitted for a single collision of the beams in the energy range E γ < ∼ 240 eV. It seems that CBS can be a potential tool for optimizing collision...
متن کاملRadiation from polarized electrons in oriented crystals at high energy
Radiation from high energy electrons in an oriented crystal can be considered in a frame of the quasiclassical operator method which appears to be a most satisfactory approach to the problem. Under some quite generic assumptions the general expression is derived for the probability of circularly polarized photon emission from the longitudinally polarized electron in oriented crystal. The partic...

Introduction: In clinical electron beams, most of bremsstrahlung radiation is produced by various linac head structures. This bremsstrahlung radiation dose is influenced by the geometry and construction of every component of the linac treatment head structures. Thus, it can be expected that the amount of the contaminated photon dose due to bremsstrahlung radiation varies among different linacs,...
