【摘要】 为研究低能重离子辅照处于生命活跃期生物样品产生的生物效应 ,基于北京大学重离子物理所的 4 5MeV静电加速器和 2x6MeV串列加速器 ,建立了一套能够在大气或溶液环境中辅照生物样品的离子束设备。该装置可以提供的离子包括从H到O的多种元素 ,引出能量最大可以达到 2 0MeV ,辅照剂量可以在 10 5～ 10 14 ions cm2 范围内调节。更多还原

【Abstract】 In order to study the biological effect of water contained living cells irradiated with energetic heavy ions, a beamline is set up based on the 4.5?MV and 2×6?MV accelerators in Peking University. This facility can irradiate many kinds of biological samples in the atmosphere or solutions, includes the growing crops seeds, microorganism and animal cells. It can provide H, He, C and O ion beams with energies from several hundreds keV to tens MeV; the irradiation doses can be in the range from 10 5 to 10 16 ions/cm 2.更多还原
