An Investigation of Bremsstrahlung Reflection in a Dense Plasma Focus (DPF) Propulsion Device
The dense plasma focus device is one of the few fusion systems that is capable of burning advanced fuels such as D – He and p – B. An study has been performed and shown that three main requirements must be satisfied to reach breakeven for DPF fusion: a high Ti/Te ration (~ 20), an order of magnitude higher pinch lifetime, and the reflection and absorption if at least 50% Bremsstrahlung radiatio...
متن کاملElectron-Electron Bremsstrahlung in a Hot Plasma
Using the differential cross section for electron-electron (e-e) bremsstrahlung exact to lowestorder perturbation theory the bremsstrahlung spectra and the total rate of energy loss of a hot electron gas are calculated. The results are compared to the nonrelativistic and extreme-relativistic approximations available and to previous work. The e-e contribution to the bremsstrahlung emission of a ...
متن کاملBremsstrahlung in dense matter and Landau-Pomeranchuk-Migdal effect
Bremsstrahlung is usually treated in second order perturbation theory of QED, yielding the well-known BetheHeitler formula [1]. In dense media, medium effects have to be accounted for. Successive scattering of high energy electrons in amorphous media [2] significantly suppresses the photon spectrum at low photon energies compared to Bethe-Heitler theory. This effect, known as LandauPomeranchuk-...
متن کاملThe equilibrium of dense plasma in a gravity field
The equilibrium of dense plasma in a gravity field and problem of a gravity-induced electric polarization in this matter are discussed. The calculation for metals performed before shows that both-the gravity-induced compressive strain and the gravity-induced electric field-are inversely proportional to their Young moduli. The calculation for high dense plasma, where Young modulus is equal to ze...
متن کاملNeutrino-electron scattering in a dense magnetized plasma.
We derive general expressions for the cross section of neutrino scattering on electrons in dense, hot stellar matter, in the presence of strong magnetic fields. Numerical calculations of the scattering cross sections at various densities, temperatures and magnetic fields, are performed. Strong, quantizing magnetic fields modify significantly the angular and energy dependence of the scattering c...
