Description
In recent years, there has been an increasing demand for high-intensity beams related to electron beam irradiation, such as mass production of nuclear-medicine examination by using 99Mo and high-efficiency production by material modification through material irradiation. While the acceleration of high-current beams can be realized by using a superconducting cavity, a compact accelerator is desirable for general-purpose irradiation beams. In this paper, we designed a 10 MeV, 50 mA high current beam irradiator for practical use based on the experimental results of highly efficient production of nanocellulose by wood irradiation. The conceptual design of the accelerator, which consists of the electron gun, the superconducting cavity, and the irradiation section, was carried out. Especially, we designed a 10 MeV, 50 mA high-current beam accelerator by using a new Nb3Sn superconducting cavity. We estimated how compact the accelerator can be and how much the operating electrical power can be suppressed.
