【摘要】 在核技术应用中,电子加速器是辐照加工产业化的基础和关键设备,因此,电子辐照加速器的生产与制造占有突出地位。本文主要介绍了中国原子能科学研究院和原子高科股份公司共同开发用于辐射消毒灭菌和食品保鲜的10MeV/15kW高能大功率电子直线辐照加速器研制和实际应用。该装置经过近两年辐照加工生产稳定可靠运行工作,证明该新型辐射装置的设计、生产、制造是成功,解决了强流电子束的加速、传输、引出等以及大功率下电子直线加速器稳定运行的关键技术,突破了大功率、长脉冲的调制器电源系统设计、制造技术,发展具有我国自主知识产权的高能大功率电子直线辐照加速器技术,提升了我国辐照加速器制造技术和产业化的能力与水平。更多还原

【Abstract】 Electron linacs are the key devices for the irradiation processing industrialization in the application of nuclear technology.Therefore the R & D of electron linacs is very important.A 10 MeV 15kW class electron linac for sterilization of medical devices and food has been designed and built at CIAE and HTA.The details of it are presented in this paper.The accelerator facility has been used for different food commodities treatment for about two years,which demonstrated that it is a very successful new type of device for irradiation processing.During the R & D of the accelerator facility,we developed some key technology such as the accelerating,transportation and extraction of high intensity electron beams,the design and manufacture of high voltage pulse modulator with high power and long pulse,and the high power stable operation of the accelerator facility.We promote the technology of electron linacs for irradiation processing in china and this upgrades Chinese manufacture technique and the industrialization capability of this type of accelerator facility.更多还原
