Outline of Final Research Achievements

Intense beams of gamma-rays are generated from solid density plasmas generated by irradiations of ultra-intense laser pulses. By gamma-rays transporting through a solid density target, electron-positron pair creations and photo-nuclear reactions take place. In order to investigate characteristics of positrons and neutrons, we developed a new simulation code by including gamma-ray transport through material into Particle-in-Cell code. Using the code, we have shown that quasi-mono-energetic positron beams with spectral peak energy beyond 100 MeV, and high flux of neutron beams are generated from high-Z material. The beam characteristics dependence on laser and target parameters are explored by numerical simulations. A laser-driven positron beam, and a neutron beam are proposed.

Academic Significance and Societal Importance of the Research Achievements

本研究では、電磁的相互作用を扱う粒子シミュレーションコードにγ線と原子核との相互作用を取り入れた新しいコードを開発し、それを用いることでレーザー光を固体へ照射することで発生する電子や中性子線の特徴を明らかにした。開発したシミュレーションコードを利用することで、プラズマ運動や輻射発生、原子核反応等を含む多様な高エネルギー密度プラズマ現象の解明が期待できる。また、超高強度レーザーを用いた新しい陽電子線や中性子源の提案により、今後の実験研究への指針を示すことができた。
