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 e...

Introduction The Advanced Photon Source (APS), as well as other third-generation synchrotron light sources, uses permanent magnets in the insertion devices to produce x-rays for scientific research [1,2]. When placed in a high-energy storage ring, these permanent magnets are subjected to irradiation from synchrotron radiation, high-energy bremsstrahlung, and bremsstrahlung-produced photoneutron...

The spectral properties of a hybrid steady thermal-nonthermal isotropic plasma are studied. The involved emission mechanisms are thermal bremsstrahlung, nonthermal bremsstrahlung, cyclotron and nonthermal synchrotron. Formulas are derived to calculate the emissivities and absorption coefficients of all these processes. Calculations show that the nonthermal synchrotron and the thermal bremsstrah...

Visible and near-infrared electron–ion bremsstrahlung measurements in fusion research devices, used to determine the effective ionic charge (Zeff), are often plagued by pollutant emission from the cool-edge region. The primary sources of visible and near-infrared non-bremsstrahlung continuum emission in the Madison Symmetric Torus arise from electron–neutral interactions, and the pollutant emis...

Copious x-ray production is shown to attend the collisions of suprathermal (?MeV) protons with ambient electrons,via a process of inverse bremsstrahlung. Such suprathermal protons have been detected in cosmic rays and in solar f lare events; the inverse bremsstrahlung of such cosmic ray protons is expected to make a significant contribution to the diffuse sky background of x-rays and supratherm...

We review the developments made during the last decade in the theory of polarization bremsstrahlung in the non-relativistic domain. A literature survey covering the latest history of the phenomenon is given. The main features which distinguish the polarization bremsstrahlung from other mechanisms of radiation are discussed and illustrated by the results of numerical calculations.

We briefly discuss GLAST’s capabilities for observing high-energy radiation from various energetic phenomena in our solar system. These emissions include: bremsstrahlung, nuclear-line and pion-decay gamma-radiation, and neutrons from solar flares; bremsstrahlung and pion-decay gamma radiation from cosmic-ray interactions with the Sun, the Moon, and the Earth’s atmosphere; and inverse Compton ra...
