Outline of Research 

Ion beams of several to several tens of MeV per nucleon can be obtained by irradiating a target such as a thin film or a gas with an ultra-short high peak power laser. At the Kansai Photon Science Institute, we have been conducting research and development of laser-driven ion acceleration using an ultra-short high peak power laser (J-KAREN-P). We are going to upgrade this technology to commercialize as a compact accelerator that uses the laser-driven ion acceleration phenomenon. If we can achieve this, we will be able to materialize the practical application of laser acceleration, which has not yet been realized. The laser-driven ion bunch is expected to generate high-density, short-pulse ion bunches, which are difficult to produce with conventional accelerator technology, and is expected to provide important insights into the operation of accelerators at high current densities.

On the other hand, QST offers heavy-ion cancer therapy, which is a proven and gentle form of radiation therapy for cancer patients. Heavy-ion therapy is characterized by its high biological effect and local controllability, and has been shown to be highly effective in treating unresectable pancreatic cancer, for example. On the other hand, heavy-ion cancer therapy requires a large accelerator to produce heavy-ion beams with sufficient energy for treatment, and its miniaturization is a challenge for its widespread use. As a part of the QST Innovation Project, a next-generation heavy-ion cancer therapy device (Quantum Scalpel) is now under development with using superconducting accelerator technology and laser acceleration technology to realize a compact device. In this project, we are conducting a proof-of-concept study of a laser-driven injector for a next-generation superconducting synchrotron as an injector of a quantum scalpel by utilizing the above-mentioned advanced research and development capabilities of laser acceleration technology in JST's "Development and Demonstration of Laser-Driven Quantum Beam Accelerator" project for creating a future society. Research is being conducted. 

Specifically, we will generate laser-driven ion beams, including carbon beams, using a high repetition-rate, ultrashort high-peak-power Ti:sapphire laser in cooperation with the X-ray Ultrafine Structure Processing Project, and evaluate their characteristics. This will lead to the development of the quantum scalpel injector mentioned above, as well as research on the interaction of the high-energy ion bunch with materials and living organisms.

Main Research Activities

 Development of a laser-accelerated carbon ion source​

​Particle therapy using heavy-ion beams has been attracting attention in recent years from the viewpoint of quality of life because of its low physical burden on patients and ease of reintegration into society after healing. However, there are currently only seven heavy-ion cancer treatment facilities in Japan, including those under construction, and the number of patients who can be treated remains at about 0.2% of all new cancer patients in Japan. In order to promote the use of heavy-ion cancer therapy, it is necessary to downsize the equipment. With the support of the JST-MIRAI program and the QST Innovation Project, KPSI is conducting research to downsize the injector for the main synchrotron accelerator by using laser-driven ion acceleration technology (Figure 1).
