完成了中子发生器的关键装置——真空氚钛靶系统的设计方案,并对影响氚钛靶寿命的各个因素及靶温升对氚钛靶寿命的影响做了介绍,着重研究旋转靶的温度变化瞬时分析的新方法。该方法将旋转靶的受热区域分为若干个相等的受热点,利用循环往复的“跳格”加热的方式完成旋转靶的瞬态分析,计算结果表明:通过该方法,能够控制旋转靶的靶点温升在允许温度范围之内。
The design of the vacuum tritium-titanium target system, which is the key device of the neutron generator, has been completed. The factors affecting the lifetime of the tritium-titanium target and the influence of the target temperature rise on the target lifetime of the tritium-titanium target are introduced. A New Method of Instantaneous Analysis of Temperature Change. In this method, the heated area of the rotating target is divided into several equally heated spots, and the transient analysis of the rotating target is accomplished by means of a circularly repeated “jump grid” heating. The calculation results show that the rotating target can be controlled by the method The target temperature rise is within the allowable temperature range.
