根据高产额（＞１．５×１０（１０）ｎ／ｓ）中子管对引出／加速系统的要求，完成了在１８０ｋＶ引出／加速电压下，加速离子束流１．１ｍＡ的新型屏蔽式引出／加速系统的物理设计，与普通中子管比较，加速电压增加５０％，束流增加一个数量级，中子产额增加一个数量级，实现了系统的结构优化。经长期实践考验证明，系统的物理设计合理，为更高产额中子管的研制奠定了基础。
Based on the high-yielding (> 1.5 × 10 (10) n / s) neutron tube extraction / acceleration system requirements, a new shielded extraction of 1.1 mA accelerated ion beam at 180 kV extraction / acceleration voltage was completed / Accelerating the physical design of the system, compared with the ordinary neutron tube, the accelerating voltage increased by 50%, the beam current increased by an order of magnitude, and the neutron yield increased by an order of magnitude to achieve structural optimization of the system. Proved by long-term practice, the physical design of the system is reasonable, laying a foundation for the development of higher yield neutron tubes.
