在ADS(Accelerator Driven Sub-critical System,加速器驱动的次临界系统)中,次临界反应堆在加速器中子源的作用下维持链式裂变反应。次临界度监测是ADS研究中的一项重要内容,跳源法是测量次临界度的行之有效的方法之一,可以通过切断加速器束流测量次临界反应堆内中子通量的
In ADS (Accelerator Driven Sub-critical System), a sub-critical reactor maintains a chain-fission reaction under the action of an accelerator neutron source. Sub-criticality monitoring is an important part of ADS research. One of the most effective ways to measure sub-criticality is to use the jumper source method. The neutron flux in the subcritical reactor can be measured by cutting off the accelerator beam
