摘要

PROBLEM TO BE SOLVED: To stably accelerate charged particles to have high energy at a high beam controllability by a constitution possible of downsizing.;SOLUTION: Intensity I_b of the main portion having the highest intensity in this pulse output is the intensity high enough to ionize this gas up to a first ionization degree. When pulse laser light having the intensity of I_b comes to relativistic self-focusing in plasma, I_b is set so that this gas is ionized to a second ionization degree higher than the first ionization degree. Moreover, before this main portion, a precursor portion having the intensity I_a lower than I_b exists. The intensity I_a of the precursor portion has the intensity high enough to ionize this gas up to a third ionization degree lower than the first ionization degree. By this precursor portion, in the plasma before the main portion is irradiated, an optical waveguide structure is formed. In irradiation of the main portion, since the pulse laser light can be propagated in this optical waveguide structure, an accelerating field of sufficient length can be formed stably.;COPYRIGHT: (C)2011,JPO&INPIT
