From theCambridge English Corpus The 13-cm radius outer wall is permitted to emit electrons where the plasma is in contact. From theCambridge English Corpus Where the plasma is in contact with the outer wall,electronspace-chargelimited emission is permitted. From theCambridge English Corpus The mass of the plume slab is determined by the amount of material ejected from the target when thermalized by theelectronbeam. From theCambridge English Corpus It is then essential that such plasmas can be accurately described in their fundamental parameters, namelyelectrondensity and temperature. From theCambridge English Corpus The analysis we present is not restricted toelectron-ion plasmas, the result is also valid forelectron-positron plasmas. From theCambridge English Corpus Charged particle acceleration by an intense wake-field excited in plasmas by either laser pulse or relativisticelectronbunch. From theCambridge English Corpus In this process, the energy absorbed by the electrons during the interaction with the laser pulse is converted into both radiation and ion kinetic energy. From theCambridge English Corpus We observe that the value of the transverse emittance of theelectronbeam is a crucial parameter for the production of monochromatic radiation. From theCambridge English Corpus These results are useful for description ofelectron-beam propagation in the solar corona, which is a source of sporadic radiation. From theCambridge English Corpus The purpose of this paper is to study the original direction of the radiation excited byelectroncyclotron maser instability or the beam-plasma instability. From theCambridge English Corpus If the freeelectronremains free after the collision, we speak of a free-free collision. From theCambridge English Corpus Evidence of enhanced effective hotelectrontemperatures in ultraintense laser-solid interactions due to reflexing. From theCambridge English Corpus Suppression of the potential well prevents the free electrons from recombination and, thus, no high-energy photon can be emitted. From theCambridge English Corpus These electrons may then be scattered into the chamber volume. From theCambridge English Corpus These examples are from corpora and from sources on the web.

From theCambridge English Corpus electron beam The mass of the plume slab is determined by the amount of material ejected from the target when thermalized by theelectronbeam. From theCambridge English Corpus electron configuration In general, probabilities of these processes depend on the velocity, charge, and electron configuration of the projectile, nuclear charge and density of the target material.
