A neutron capturing therapy system and a target material for use in a neutron generating device, capable of increasing the heat dissipation performance of the target material, reducing foaming, and extending the service life of the target material. The neutron capturing therapy system comprises the neutron generating device and a beam shaper. The neutron generating device comprises an accelerator and the target material. An electrically charged particle beam accelerated and generated by the accelerator interacts with the target material to generate a neutron beam. The target material comprises an acting layer, a base layer, and a heat dissipating layer. The acting layer interacts with the electrically charged particle beam to generate the neutron beam. The base layer supports the action layer. The heat dissipating layer comprises a pipe-shaped element consisting of multiple pipes arranged side by side.一種中子捕獲治療系統及用於粒子線產生裝置的靶材,能提升靶材的散熱性能,減少起泡,增加靶材壽命。本發明的中子捕獲治療系統,包括中子產生裝置和射束整形體,中子產生裝置包括加速器和靶材,加速器加速產生的帶電粒子線與靶材作用產生中子線,靶材包括作用層、基座層和散熱層,作用層與帶電粒子線作用產生中子線,基座層支撐作用層,散熱層包括由多個管並排組成的管狀件。100‧‧‧硼中子捕獲治療裝置10‧‧‧中子產生裝置11‧‧‧加速器111‧‧‧加速管20‧‧‧射束整形體21‧‧‧反射體22‧‧‧緩速體23‧‧‧熱中子吸收體24‧‧‧輻射屏蔽體25‧‧‧射束出口30‧‧‧準直器40‧‧‧治療台50‧‧‧輻射屏蔽裝置200‧‧‧患者T‧‧‧靶材C‧‧‧帶電粒子線N‧‧‧中子線M‧‧‧腫瘤細胞D1‧‧‧第一冷卻管D2‧‧‧第二冷卻管
