产额大于1.5×10^(10)n/s中子管引出/加速系统的物理设计

A Physical design of extracting/accelerating system for a neutron tube with yield of 1.5 × 10^（10）n/s

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。

Described is a new screened type of extracting/accelerating system thataccelerates ion beam up to 1.1mA and 180kV based on the requirements of high-yieldneutron tube. The optimization of structure has been realized and a neutron yield ofmore than 1.5×10~10n/s has reached. The long-term practices prove this physicaldesign is rational and lays a foundation for developing neutron tubes with still higheryield.
