CO2 guided plasma channel for light ion beam transport

Uniform, long and stable plasma channels for the light ion beam transport were formed by the guidance of CO2 laser. The typical required laser energy and applied electric field were 2 mj/cm⁻³·mbar and 10 V/cm-mbar, respectively. The ion beam transport experiments were performed. The energy loss in the channel was slightly larger than that estimated from the classical theory.
