Description
Special Seminar
In plasma-based acceleration the space charge or radiation pressure of an intense particle beam or laser pulse creates a plasma wave wake with a phase velocity near the speed of light. Charged particles then surf on this wake to ultra-high energies in very short distances. There has been tremendous recent progress including the experimental demonstration of mono-energetic electrons beams in excess of 1 GeV using a laser and the energy doubling of some electrons from the SLAC beam from 42 to 84 GeV in less than one meter. Computer simulations have played an indispensible role in this development. Due to the nonlinear and kinetic nature of how a laser and particle beam interacts with the plasma, the tool of choice has been particle-in-cell simulations. With the advent of massively parallel computers and improved algorithms full-scale simulations in three dimensions of experiments is now possible. In this talk, I will give a status of the field, describe how computer simulations have impacted, are impacting, and will impact progress in this field, and describe what can be expected in the next decade both experimentally and computationally.
