TI - Present Status of HIMAC ECR Ion Sources J2 - Proc. of ECRIS2020, East Lansing, MI, USA, 28-30 September 2020 CY - East Lansing, MI, USA T2 - International Workshop on ECR Ion Sources T3 - 24 LA - english AB - High-energy carbon-ion radiotherapy is being carried out at Heavy Ion Medical Accelerator in Chiba (HIMAC). Over 12000 cancer patients have been treated with carbon beams having energies of between 56-430 MeV/u since 1994. There are two injectors in the HIMAC for medical and experimental use. First injector consists of two ECR ion sources and one PIG ion source, the RFQ linac and the DTL. Usually, this injector suppling the carbon ion for cancer therapy and various ion such as H, He, Fe, Xe are accelerated for biological and physical experiment. The 10 GHz NIRS-ECR ion source produce the carbon ion for cancer therapy. The 18 GHz NIRS-HEC ion source produce He to Xe ions for experimental use. Second injector consists of the compact ECR ion source with all permanent magnet, the RFQ linac and the APF IH-DTL. This injector supplies the carbon ion for experimental use. Additionally, we tried production of the Indium and the Tin ions by using the In(C5H5) and the Sn(i-C3H7)4 at the NIRS-HEC. Beam current of the 115In²⁰⁺ and 120Sn¹⁸⁺ were 90 and 15μA, respectively. Present status of ECR ion sources and some development will be described.
