A quadrupole accelerator includes a center member, a first side member, and a second side member. The center member includes a center outer frame part, a first electrode and a second electrode. The first side member includes a first side outer frame part, a first wall part and a third electrode. The second side member includes a second side outer frame part which extends from the second side outer frame part toward an outside, a second wall part and a fourth electrode. The center member is formed seamlessly. The first side member is formed seamlessly. The second side member is formed seamlessly. The first side outer frame is fixed to a first side of the center outer frame part by a first fixing member. The second side outer frame is fixed to a second side of the center outer frame part by a second fixing member.

Quadrupole accelerator and a method for manufacturing quadrupole accelerator

A method of production of a radio frequency accelerator which has a tubular partwhich forms an acceleration cavity, including a temporary assembly step of making a plurality of component memberstowhich have shapes obtained by splitting the tubular partmate with each other to temporarily assemble them into the shape of the tubular partand a welding step of welding the plurality of component memberstotogether. The temporary assembly step includes a step of placing, inside of the tubular part, support membersfor contacting the inside surface of the tubular partand supporting the tubular partfrom the inside, and the welding step includes a step of welding the plurality of component memberstoalong the butt linesby friction stir welding.
