Monoenergetic Electron Beam

Regarding both step by step and direct ionization by electron impact, and including losses from radiative recombination and charge exchange, a simple model for calculation of charge state densities in electron beam multiply charged ion sources has been developed. The diffusion of the created charged particles out of the ionization volume is included in the model. A monoenergetic electron beam of high current density interacts with a gas at a pressure range from 10-6 to 10-4 Torr. The calculations were performed for Argon, Krypton and Xenon with an impact energy from 2 keV to 10 keV. Influences of several elementary processes were discussed in regard to developments of new types of multiply charged ion sources.

ABSTRACTPicosecond time resolved photoluminescence and photoconductivity measurements are performed to investigate the influence of high intensity illumination on the properties of Fullerene crystals. A highly nonlinear dependence of both the photoluminescence characteristics and the photoconductive response of the fullerenes is seen and temperature dependent measurements indicate that the nonlinear processes are associated with an insulatormetal-like phase transition in the material, and thus that the electronic properties of the excited state are dramatically altered at high excited state densities. The observed behaviour is compared and contrasted to the changes in the optical properties upon photochemical modification of the pristine material via Raman spectroscopy. Application of a simple phenomenological model to calculate the contribution of intermolecular exchange and correlation energies in the excited state supports the proposal that the observed phenomena originate from a Mott-like phase transition. A further manifestation of this behaviour is the emergence of a broadband electroluminescent emission above a critical injection current density.
