摘要实验研究了惯性静电约束聚变三重栅系统的工作特性，以使系统在低气压下获得足够的聚变反应速率，从而使系统的运行不受辉光放电电压、电流和气压的限制。当灯丝提供足够的电子时，在相同的放电电流和电压下，工作气体压力降低到原来的1/5。虽然所实现的气体压力区域仍然是离子束和背景气体之间的聚变反应占主导地位的区域，但在三栅极系统中由气体压力归一化的中子产额显示出比常规单栅极系统更高的值。
Abstract Performance characteristics of an inertial electrostatic confinement fusion triple-grid system are experimentally studied to provide an ample fusion reaction rate under a lower-gas-pressure region to make the operation free from glow discharge restrictions between the discharge voltage, current, and gas pressure. With a filament to provide sufficient electrons, the operating gas pressure is found to reduce down to 1/5 for the same discharge current and voltage. Although the gas pressure region that was achieved still remains the region where the fusion reaction between the ion beam and background gas is dominant, the neutron yield normalized by the gas pressure in the triple-grid system shows higher value than the conventional single-grid system.
