Electromagnetic instabilities for relativistic beam-plasma interaction in whole k space: nonrelativistic beam and plasma temperature effects.
For the system formed by a relativistic electron beam and its plasma return current, we investigate the effects of both transverse and parallel beam and plasma temperatures on the linear stability of collective electromagnetic modes. We focus on nonrelativistic temperatures and wave-vector orientations ranging from two-stream to filamentation instabilities. Water-bag distributions are used to m...
متن کامل1D PIC simulation study of nonlinear beam plasma interaction
Since the early days of plasma simulation studies, superthermal electrons having energies much greater than the injected beam electrons have been widespreadly observed. The origin of such superthermal tail in the electron velocity distribution is generally believed due to the second order Fermi acceleration, i.e., the acceleration due to turbulence. In this paper, generation of superthermal ele...
متن کاملBeam - Beam Interaction
A two dimensional simulation study of the beam-beam interaction at SPEAR indicates that quantum fluctuations affecting the horizontal betatron oscillation play a critical role in the vertical beam blowup.

Beam - Beam Interaction : Luminosity , Tails
Observations of the beam-beam interaction at SPEAR, CESR, PETRA and PEP are discussed. They are sufficiently similar that a simple prescription can be formulated to describe the behavior of the luminosity as a function of current including the peak values. With this prescription the interpretation of various methods of increasing the luminosity, such as the reduction of the vertical betatron fu...
