Tomonao Hosokai is a Professor at the Department of Quantum Beam Physics within the Institute of Scientific and Industrial Research (SANKEN) at Osaka University. He also serves as Team Leader at RIKEN Spring-8 Center Laser Acceleration Development Team. His research focuses on developing compact particle acceleration technologies using high-intensity lasers, with applications spanning from fundamental plasma physics to medical and industrial applications. Professor Hosokai's research interests center around laser-plasma acceleration, where his team develops table-top GeV-class laser accelerators using plasma waves excited by intense laser pulses. His work extends to quantum beam applications including beam-driven drug discovery, electron linear accelerator applications, and high-power laser processing for material modification and strengthening. His laboratory employs advanced numerical simulations to understand relativistic plasma behavior and develops plasma control techniques for stable electron acceleration. His recent publications reveal a strong focus on multi-stage laser wakefield acceleration, electron injection control, and practical applications of quantum beams. Key trends include developing modular supersonic nozzles for stable acceleration, controlling electron self-injection with asymmetric gas-jet nozzles, and exploring applications in drug discovery and material science. Hosokai leads the Hosokai Laboratory which operates several major research facilities including the LAPLACIAN laser acceleration platform, L-band electron accelerator/THz FEL system, laser peening test equipment, gas jet laboratory, and a high-performance PC cluster with 1024 CPU cores. His team actively participates in international collaborations including the EuPRAXIA project, which aims to develop compact, cost-efficient particle and radiation sources.
