100MeV质子回旋加速器单粒子效应实验技术及评价方法研究

The sustainable development of China's manned space program, lunar exploration program, deep space exploration etc space missions and with the continuously development of semiconductor manufacture industry typically increase the importance of integrated circuits’ single event effects. Proton single event effects is one of the key factors influencing the radiation safety of electronic devices in space, but due to the lack of middle-energy proton accelerators, experimental research of proton single event effects work basically a blank state in our country. In July 2014, the beam had been successfully elicited at Beijing tandem upgrade project "100MeV proton cyclotron". This cyclotron is the first middle energy proton accelerator in our country which creating a good opportunity for the study of proton induced single event effects. Our project intends to base on "100MeV proton cyclotron" research techniques and evaluation methods for 100MeV proton single event effects, to breakthrough some key technologies of large-size, high uniformity beam elicit for proton irradiation facility construction, to establish a theoretical method which include calculation proton and semiconductor device material nuclear reaction data and single event effects cross section induced by proton, to provide technical and theoretical support for establish engineered proton irradiation research system. This project will play an importance role for earlier complete the construction of 100MeV proton irradiation facility, and promote advanced electronic components application in space satellites and weaponry.

我国载人航天、探月工程和深空探测等航天任务的持续推进，以及半导体工艺技术的迅速发展，促使集成电路单粒子效应研究越发重要，而质子单粒子效应是影响空间电子器件辐射安全的关键因素之一，但是由于缺乏中能质子加速器，我国中能质子单粒子效应实验研究工作基本处于空白状态。北京串列升级工程“100MeV质子回旋加速器”于2014年7月成功出束，该器填补了我国中能质子加速器空白，为质子单粒子效应研究创造了良好机遇。本课题拟围绕“100MeV质子回旋加速器”，开展100MeV质子单粒子效应实验技术及评价方法研究，突破质子抗辐射实验装置建设中大尺寸、高均匀性束斑获取及评价关键技术，建立质子与半导体器件材料核反应微观数据以及单粒子效应截面的理论计算方法，为建立工程化的质子抗辐射研究体系提供技术及理论支持。课题工作对早日建成100MeV质子抗辐射实验装置、促进先进电子元器件在空间型号及武器装备中的应用具有重要意义。
