Outline of Final Research Achievements

Electric-charged partilce beams that are generated and accelerated by particle accelerators are utilized by fundamental science and industrial/medical applications ranging widely from elementary-particle/nulear physics, material development and to biology. The utilized particle-beams are dumped through the nuclear reactions into the final heat energy, but with some radioactivity. This is a problem and diffective asspect of current beam-dump system. We studies the new method of clean and compact beam-dump where beam is injected into an appropriate gas-chamber with laser and the generated plasma wake-field transfers the beam energy to plasma energy with minimum radioactivity. We successfully found appropriate conditions of gas-chember and laser for assumed partilce-beams to be transfered into plasma energy by simulation calculation.

Academic Significance and Societal Importance of the Research Achievements

速器で生成・加速された荷電粒子ビームは,素粒子・原子核物理学や物質・生命科学等の基礎科学から産業・医療利用に至るまで広範囲に利用されている。荷電粒子ビームは使用後にビームダンプ装置に入射され、核反応を伴う過程を経て熱エネルギーとして廃棄されるが、放射化が伴うという欠点がある。本研究では、適切に調整したガス・チェンバーにレーザーと荷電粒子ビームを同時に入射することで発生するプラズマ航跡場によって、荷電粒子ビームをプラズマに変換して放射化を最小限に抑制して廃棄する方法をシミュレーション計算で明らかにした。今後、荷電粒子ビームを利用する全ての施設において、放射化の問題を回避できる可能性が拓けた。
