| description | To provide a low-energy charged particle beam transport system and charged particle beam transport method in BNCT.SOLUTION: An accelerator 10 emits a low-energy charged particle beam C. A target 12 includes lithium, and generates a neutron beam N upon irradiation with the charged particle beam C transported through the beam transportation channel 11. A moderator system 13 reduces the energy of the neutron beam N generated from the target 12 to a thermal energy region. A converging lens 14 is configured in the beam transportation channel 11 by arranging a prescribed number of quadrupole electromagnets from the upstream of the charged particle beam C along the irradiation direction of the charged particle beam C and by arranging a prescribed number of octapole electromagnets from a downstream-side quadrupole electromagnet 14c along the irradiation direction of the charged particle beam C. A converging lens control unit 102 controls the magnetic field of the quadrupole electromagnets and the octapole electromagnets, whereby the beam profile of the charged particle beam C in the width direction is expanded and uniformized.SELECTED DRAWING: Figure 1
【課題】ＢＮＣＴにおける低エネルギーの荷電粒子線輸送システム及び荷電粒子線輸送方法を提供する。【解決手段】加速器１０は、低エネルギーの荷電粒子線Ｃを出射する。ターゲット１２は、リチウムを含み、前記ビーム輸送路１１から輸送された荷電粒子線Ｃの照射を受けて中性子線Ｎを発生させる。減速材システム１３は、ターゲット１２から発生した中性子線Ｎのエネルギーを熱エネルギー領域まで低下させる。集束レンズ１４は、ビーム輸送路１１の内部において、所定数の四重極電磁石を、荷電粒子線Ｃの上流から荷電粒子線Ｃの照射方向に沿って配置するとともに、所定数の八重極電磁石を、下流側の四重極電磁石１４ｃから荷電粒子線Ｃの照射方向に沿って配置することで構成される。集光レンズ制御部１０２は、前記四重極電磁石と前記八重極電磁石の磁場を制御することで、前記荷電粒子線Ｃの幅方向のビームプロファイルを広げるとともに、均一化する。【選択図】図１ |
