Photon Splitting in Strongly Magnetized Plasma
The process of photon splitting, becomes allowed in the presence of strong magnetic field. We calculate the influence of magnetized plasma on the photon splitting absorption coefficient. We calculate the refraction coefficients and polarization vectors with the inclusion of the vacuum terms at an arbitrary value of the magnetic field, and then find photon splitting matrix element taking into ac...
متن کاملComment on “photon Splitting in Strongly Magnetized Objects Revisited”
I point out that the results stated in the recent articles on photon splitting by Wunner, Sang, and Berg and by Wentzel, Berg, & Wunner directly contradict an earlier analytic and numerical calculation that I performed of the same process using Schwinger’s proper time method, for strong magnetic fields and general energies below the pair production threshold. The results of Wunner et al. and We...
متن کاملIntense Reb Transport in a Weakly Magnetized Plasma*
Intense relativistic electron beams (REBs) have been used in various applications for the purpose of high-power microwave (HPM) generation. By injecting the beam into a plasma, it is possible to overcome the space-charge limiting current because of charge and current neutralization provided by the plasma. Our goal in this experiment was to study beam transport issues which may be relevant to th...
متن کاملPhoton Splitting and Pair Creation in Highly Magnetized Pulsars
The absence of radio pulsars with long periods has lead to the popular notion of a high P “death line.” In the standard picture, beyond this boundary, pulsars with low spin rates cannot accelerate particles above the stellar surface to high enough energies to initiate pair cascades, and the pair creation needed for radio emission is strongly suppressed. In this paper we explore the possibility ...
متن کاملSelf-generated magnetic dipoles in weakly magnetized beam-plasma system.
A self-generation mechanism of magnetic dipoles and the anomalous energy dissipation of fast electrons in a magnetized beam-plasma system are presented. Based on two-dimensional particle-in-cell simulations, it is found that the magnetic dipoles are self-organized and play important roles in the beam electron energy dissipation. These dipoles drift slowly in the direction of the return flow wit...
