Abstract

Much research in recent years has focused on circular accelerators that accelerate and store secondary particles with a large momentum spread, such as muons, unstable nuclei and heavy ions with different charge states. A fixed field alternating gradient (FFAG) accelerator with large transverse and momentum acceptance has obvious advantages for such requirements. A versatile beam injection method is required to accelerate secondary particles with a large momentum spread and different charge states with an FFAG accelerator. In the present study, a method for charge exchange injection of positive heavy ions using the large momentum acceptance of an FFAG accelerator is proposed. A charge injection system, which converts a He1 + beam to a He2 + beam, is developed for a 150 MeV FFAG accelerator at the Center for Accelerator and Beam Applied Science (CABAS) of Kyushu University. As the first step to verify the injection method, orbits shift from one charge state to the other is demonstrated. This is the first demonstration of heavy ion injection using an FFAG accelerator.

固定场交变梯度加速器的重离子注入

近年来的许多研究都集中在环形加速器上，这种加速器可以加速和储存具有较大动量分布的二次粒子，如μ介子、不稳定原子核和具有不同电荷状态的重离子。具有大横向和大动量接受能力的固定场交变梯度（FFAG）加速器在满足此类要求方面具有明显的优势。要利用 FFAG 加速器加速动量分布大且电荷状态不同的二次粒子，需要一种多功能的束流注入方法。本研究提出了一种利用 FFAG 加速器的大动量接受能力进行正重离子电荷交换注入的方法。九州大学加速器和光束应用科学中心（CABAS）为 150 MeV FFAG 加速器开发了一套电荷注入系统，可将 He1 + 射束转换为 He2 + 射束。作为验证注入方法的第一步，演示了从一种电荷状态到另一种电荷状态的轨道转换。这是利用 FFAG 加速器进行重离子注入的首次演示。

期刊介绍： Progress of Theoretical and Experimental Physics (PTEP) is an international journal that publishes articles on theoretical and experimental physics. PTEP is a fully open access, online-only journal published by the Physical Society of Japan. PTEP is the successor to Progress of Theoretical Physics (PTP), which terminated in December 2012 and merged into PTEP in January 2013. PTP was founded in 1946 by Hideki Yukawa, the first Japanese Nobel Laureate. PTEP, the successor journal to PTP, has a broader scope than that of PTP covering both theoretical and experimental physics. PTEP mainly covers areas including particles and fields, nuclear physics, astrophysics and cosmology, beam physics and instrumentation, and general and mathematical physics.
