We study the effects of redistributing superthermal electrons on Bremsstrahlung radiation from hot relativistic plasma. consider thermal and nonthermal distribution with an energy cutoff in phase space explore impact losses. discover that redistribution into lower energies reduces radiative losses, which is contrast to nonrelativistic Finally, we discuss possible relevance our results for open ...

We describe a work in progress on the reconstruction of radial profiles for the ion effective charge Z eff on the TEXTOR tokamak, using statistical data analysis techniques. We introduce our diagnostic for the measurement of bremsstrahlung emissivity signals. Z eff profiles can be determined by Abel-inversion of line-integrated measurements of the bremsstrahlung emissivity (ǫ ff) from the plasm...

Abstract A pyroelectric X-ray source is proposed, in which a lithium tantalate crystal heated by an infrared laser with wavelength of 10.6 μm. spectra measured during irradiation the radiation and natural cooling include characteristic atoms contained structural parts source, as well bremsstrahlung electrons energies above 50 keV. An 8 mm sodium chloride window was used to inject 64 W into vacu...

PURPOSE Since the first publications on intensity modulated radiation therapy (IMRT) in the early 1980s almost all efforts have been focused on fairly time consuming dynamic or segmental multileaf collimation. With narrow fast scanned photon beams, the flexibility and accuracy in beam shaping increases, not least in combination with fast penumbra trimming multileaf collimators. Previously, expe...

Effect of radiation of many photons by a single electron traversing a target is discussed. When the summary energy of emitted photons (the energy losses spectrum) is measured only, the photon spectrum is distorted comparing with the photon spectrum in one interaction. Influence of this effect is discussed for the cases (1) bremsstrahlung (described by Bethe-Heitler formula), (2) the strong Land...

The (σ, ω) model in mean-field approximation where the meson fields are treated classically, describes much of observed nuclear structure and has been employed to describe the nuclear equation of state up to the quark-gluon phase transition. The acceleration of the meson sources, for example, in relativistic heavy-ion collisions, should result in bremsstrahlung-like radiation of the meson field...

We have calculated stationary models for accretion disks around super-massive black holes in galactic nuclei. Our models show that below a critical mass flow rate of ∼ 3 10−3 ṀEdd advection will dominate the energy budget while above that rate all the viscously liberated energy is radiated. The radiation efficiency declines steeply below that critical rate. This leads to a clear dichotomy betwe...

The possibility of fusion ignition in proton-Boron$^{11}$ plasma is strongly enhanced if the energy from fusion-produced $\alpha$ particles channeled to fast protons, but an environment which most protons are thermally distributed. This hybrid thermonuclear and beam-plasma offers surprisingly large advantages either purely or fusion, neither can by themselves significantly exceed bremsstrahlung...

In the Winterberg scheme, a charge neutralized intense high-Z ion beam is axially injected into a mirror magnetic field, where it undergoes isothermal compression without significant loss of forward beam velocity. During compression , an azimuthal current is induced in the beam which then leads to ohmic heating of the beam. Simultaneously, the beam density increases to a collision dominated reg...
