Description
A compact heavy ion medical accelerator with a superconducting rotating gantry is under construction in Yamagata University. 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 a synchrotron of 430 MeV/u.
The facility has three new features: a compact building, energy-saving operation, and superconducting rotating gantry. The first is the compact building. The footprint of the building is 45x45 m, which is the smallest heavy ion treatment facility in the world. This compactness was realized by the vertical layout of the accelerator, irradiation rooms, and infrastructure equipments. The second is energy-saving operation with no idling and natural air conditioning. The third is the superconducting gantry, which is more compact than the first model built in NIRS. These features contribute to an advanced carbon ion therapy with a lower cost and a small facility. In this presentation, progress of the project and reliability of the system and infrastructure are discussed.
Summary
A Compact Heavy Ion Medical Accelerator is under construction in Yamagata University. The main features are compact building, energy-saving operation, and a superconducting rotating gantry. Progress of the project and reliability of the system and infrastructure are discussed.
