使用一维粒子代码模拟了惯性静电约束聚变（IECF）装置中的低压大电流放电，并研究了束-束聚变中离子的约束水平和中子产额。从低压操作的计算可以清楚地看出，离子的平均寿命延长了，但收敛到与阴极的几何透明度相对应的值。应用阳极半径10cm即可进行大电流放电计算（注入D2+200mA电流）。束-束反应的中子产额对压力不敏感，但在0.1mPa或更低的压力下高于束-背景反应的中子产额。
Using a one-dimensional particle code, low pressure and large current discharge in an inertial electrostatic confinement fusion (IECF) device has been simulated, and confinement level of ions and the neutron yield through beam–beam fusion have been investigated. From the calculation of low-pressure operation, it is clear that the averaged life span of ions is extended but converges to a value corresponding to the geometrical transparency of the cathode. Calculation of large current discharge (injecting D2+current of 200mA) can be carried out by applying the anode radius of 10cm. The neutron yield through beam–beam reaction is insensitive to the pressure, but is higher than that through beam–background reaction at the pressure of 0.1mPa or lower.
