Description
本実施形態は、約1Aの重陽子(デューテロン)または陽子(プロトン)の連続(CW)イオンビームを核子当り100MeV(以下、100MeV/u、同種の記載も同様)まで加速する、100MW級の線形加速器システム100である。図1は、本実施形態に係る線形加速器システム100の概略構成例を示す図である。なお、本明細書において、線形加速器システムとは、縦続接続された複数の加速器の全体を総称的に指す用語である。
それぞれの加速ギャップにおける高周波磁場の電圧および位相と、Q磁石の磁場勾配の決定方法について説明する。加速条件は、全てのセクションについて同様の処理によって決定できる。したがって、以下では、主に低βセクション加速器30を例にして説明を行う。
以下、本実施形態に係る線形加速器システム100の有利な点を、国際核融合材料照射施設(IFMIF: International Fusion Material Irradiation Facility)と比較して説明する。IFMIFは、2本の重陽子ビーム(40MeV,125mA×2)を照射する10MW級の加速器である。
上記の実施形態の構成は、本発明の技術的思想を逸脱しない範囲内で、適宜変更して構わない。上記の実施形態における、具体的なパラメータは一例に過ぎず、要求に応じて適宜変更して構わない。
40:中βセクション加速器, 50:高βセクション加速器
31,41,51:加速空洞
32,42,52:四重極磁石(Q磁石)
33,43,53:高周波電力供給部
34,44,54:高周波結合系
35,45,46,55:加速ギャップ
