摘要
离子注入生物诱变是不同于传统辐射生物学的人工诱变新方法。在离子注入生物诱变实验中 ,真空室真空度及其稳定性影响着生物样品的存活状态 ;注入剂量决定着生物样品的辐射损伤程度 ,是要求精确测量并控制的重要参量。本文介绍了以单片微机为核心的计算机系统对 5 0 ke V注入装置上离子注入生物实验实时在线控制的实施方法 。
Ion implantation biological mutation is a new different artificial mutation method from the traditional irradiation biology. For the vacuity and the vacuum stability in chamber affect the living conditions of biological sample, and the implantation dose determines the irradiation injury degree of biological sample,there are all important parameters that should be measured and controlled accurately in the experiment. In this paper, the method based on single chip microcomputer of real time controlling on line in the ion implantation biological experiment of 50 keV apparatus is introduced, and the hardware construction and software function modules are described in detail.
