Ion acceleration in a gas jet using multi-terawatt CO2 laser pulses
Abstract
This paper describes ongoing research in the Neptune Laboratory at UCLA on ion acceleration from plasmas formed in different gases using a 4-10TW CO2 laser. Our experiment is focused on acceleration of Helium and Nitrogen ions using collisionless shocks. The status of the experiment is presented. One dimensional particle-in-cell (PIC) simulations are carried out to study conditions under which a collisionless shock is launched in two interpenetrating plasmas with different charge densities and charge states.
