研究重离子生物效应的辐照装置

An irradiation equipment for investigation on biological effects of heavy ions

本文开展了重离子对植物细胞遗传学效应的研究,研究中采用了48MeV/amu的C^(6+)离子,辐照样品的束流截面直径为40mm,束流密度为10~3—10~7p/Cm^2;描述了为进行这项研究专门设计制造的重离子对植物种子的辐照装置,它包括束流监测系统、真空系统、隔离窗以及数据获取和样品自动更换系统。

An equipment irradiating plant seeds with heavy ions is described. It consists of a beam monitoring system, vacuum chamber, Ni-seperating window, data acquisition and automatic changing system for samples. The beam has a diameter of 40mm, with a density of 103 to 107 p/cm2. The first project relates to genetic effects of 48 MeV/amu C6+ heavy ions on plant cells.
