Emission, Emittance and Entropy of High Intensity Electron Beams
Abstract
The interaction of intense electromagnetic fields, such as those produced by present day and future lasers, with electric charges in matter is of both fundamental and practical interest. An important area of current research is that of controlling electron emission from metals on the femto-second scale. We propose to carry out analytical and numerical investigations of the dynamics of electrons interacting with a strong laser field. To do this we will: A. expand our present work solving the time dependent Schrodinger equation describing photoemission following the turning on of a monochromatic laser field with a femtosecond periods to include a constant electric field, two colored laser fields and carrier-envelope-phase effects. B. Work on the general problem of tunneling times using results obtained from the exact solution of the Schrodinger equation. One of our tools will be the study of the Wigner distribution function. This is ongoing work in collaboration with Dr. Don Shiffler from the Air Force Research Laboratory in Kirtland. C. Study the effect of Coulomb interactions leading to space change limitations on the current, Schottky reduction of barrier height, emittance of beams and other relevant plasma non equilibrium transport properties will also be pursued.
