説明
<p>Yamagata University has carried out a heavy ion treatment facility project since 2004. Building and treatment machine has been constructed since 2017. The carbon ion medical accelerator consists of a permanent-magnet type electron cyclotron resonance (ECR) ion source, a series of linear accelerator of radiofrequency quadrupole (RFQ) and interdigital H-mode drift tube linac (IH-DTL) with an energy of 4 MeV/u, and an alternative gradient synchrotron of 430 MeV/u. There are two irradiation rooms, one has a fixed horizontal port and the other has a rotating gantry port with superconducting magnets. Since the irradiation rooms are placed above the accelerator room, the footprint of the building is only 45×45 m, which is significantly smaller than preceding facilities. The synchrotron has a variable-energy flattop operation pattern with 600 energies. This operation enables a three-dimensional spot scanning irradiation without range shifters. A superconducting rotating gantry is equipped with a pair of improved scanning magnets in the downstream of the final bending magnets and is downsized to 2/3 of the first model built in NIRS. The construction of the building was completed in May 2019. The treatment irradiation will start in February 2021 after machine optimization and clinical beam data measurement.</p>
