HIGH-SPEED PARTICLE GENERATOR

摘要

A target (30) placed in a vacuum chamber (60) is irradiated with laser beam (L1) that is outputted from a laser beam source (10) while being condensed through a condensation optical system (20). Consequently, high-speed particles (P), e.g. protons, are generated and emitted from the target (30). Plasma emission (L2) from the target (30) incident to condensed irradiation with the laser beam (L1) is measured by means of a light measuring instrument (40) and a measurement signal therefrom is analyzed by means of an analyzer (50), thus evaluating the generating condition of high-speed particles (P). Based on the results of analysis, the condensation optical system (20) and the target (30) are controlled through an optical system moving mechanism (25) and a target moving mechanism (35), thus feedback controlling the generating condition of high-speed particles (P) at the target (30). A high-speed particle generator capable of generating high-speed particles efficiently by monitoring in real time the generating condition thereof is thereby realized.
