چکیده
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.

The UCLA Neptune Laboratory CO2 laser system has been recently upgraded to produce 3ps multi-terawatt 10μm laser pulses. The laser energy is distributed over several 3ps pulses separated by 18ps. These temporally structured pulses are applied for laser driven ion acceleration in an H2 gas jet at a measured plasma density of 2x1019cm−3. Protons in excess of 20MeV have been observed in the forwar...
متن کاملProduction of 25 MeV Protons in CO2 Laser-Plasma Interactions in a Gas Jet
At the Neptune Laboratory at UCLA, we have developed a high-power CO2 MOPA laser system which produces world record, multi-terawatt 10μm pulses. The CO2 laser pulses consist of a train of 3ps pulses separated by 18ps, each with a peak power of up to 4TW and a total pulse train energy of ∼100J. These relativistic laser pulses are used for Laser Driven Ion Acceleration in a H2 gas jet operated ar...
متن کاملLaser-plasma Interaction Studies Using above Critical Density Gas Jet Plasmas and a Multi-tw Co2 Laser*
CO2 laser-plasma interaction provides a unique parameter space for particle acceleration in a gas jet plasma taking place at a critical plasma density ncr ~ 10 cm and even at higher densities (3~10 ncr) of 10μm radiation. Here we report the latest results of our study of electron acceleration in a wide range of plasma densities 1~10 ncr using a multi-TW CO2 laser system at the UCLA Neptune Labo...
متن کاملDevelopment of a High-repetition Rate Tw Co2 Laser Driver for a Compact, Variable Species Ion Source
CO2 laser-driven ion acceleration has been used to generate monoenergetic, MeV proton beams from a gas jet plasma. Use of a gas jet is advantageous because it offers interactions at a density around the critical plasma density for 10 μm pulses (10 cm) and can be run at a repetition rate of 1-100 Hz. This opens the possibility to create a variable species ion source easily switchable from proton...
متن کاملEmerging Terawatt Picosecond Co2 Laser Technology and Possible Applications in Accelerator Physics
The first terawatt picosecond (TWps) CO2 laser is under construction at the BNL Accelerator Test Facility (ATF). TWps-CO2 lasers, having the order of magnitude longer wavelength than the well-known table-top terawatt solid state lasers, offer new opportunities for the strong-field physics research. For processes based on electron quiver motion, such as laser wakefield acceleration (LWFA), the a...
