U.S.-Japan Cooperative Research: Study of Laser Particle Acceleration

该奖项将支持德克萨斯大学奥斯汀分校物理系田岛敏教授和日本筑波高能物理国家实验室(KEK)绪方敦教授之间为期两年的美日合作科学项目。该项目的目的是研究和探索强激光加速粒子的新方法，为未来的加速器提供实验和理论上的支持。其中将要探索的项目包括激光尾场加速、电离前沿尾迹和等离子体共振腔。对更高能量的适用性将从实验和理论上进行研究。美国和日本集团的专业知识具有互补性。美国调查人员将前往筑波，根据日本小组获得的实验结果，协调和微调他们在计算、理论和激光开发方面的工作。美国团队开发了强激光短脉冲尾场激发的理论和计算模型，而日本团队则进行了带电粒子束的尾场激发实验，并组建了一组实验人员进行激光尾场激发。

This award will support a two-year U.S.-Japan cooperative science project between Professor Toshi Tajima, Department of Physics, University of Texas, Austin, and Professor Atsushi Ogata, National Laboratory for High Energy Physics (KEK), Tsukuba, Japan. The purpose of the project is to investigate and explore novel methods of particle acceleration via intense lasers experimentally and theoretically for future accelerators. Among the projects to be explored are the laser wakefield acceleration, ionization front wake, and plasma resonant cavity. The salability to higher energies will be investigated experimentally and theoretically. The expertise of the U.S. and Japanese groups are complementary. The U.S. investigators will travel to Tsukuba to coordinate and fine-tune their work on computational, theoretical, and laser development with the experimental results obtained by the Japanese group. The U.S. group has developed a theoretical and computational model of wakefield excitation by intense short laser pulses, while the Japanese group has carried out wakefield excitation experiments by a charged particle beam and assembled a team of experimentalists for a laser wakefield excitation.
