场反转组态（FRC）的等离子体密度需要降低到目前的实验制度以下，以加热等离子体并通过FRC反应器中的高能中性束维持该组态。然而，由于等离子体是在线性真空容器中产生的，与环形系统相比，在低填充压力下存在严重的击穿极限。提出了一种形成击穿极限以上的FRC的方法。预电离等离子体被压缩的强偏置场，以提高从限制区域到外部区域的等离子体流，然后在NUCTE设备上的限制场开始之前被稀释。稀释等离子体的使用使FRC的临界密度从1.1 × 10 ~（21）m ~（-3）降低到5.6 × 10 ~（20）m ~（-3），电子和离子温度之和从0.35 keV增加到0.81 keV。
The plasma density of a field reversed configuration (FRC) needs to be decreased below the present experimental regime in order to heat the plasma and sustain the configuration by a high energy neutral beam in an FRC reactor. However, as the plasma is produced in a linear vacuum vessel, there exists a severe breakdown limit at a low fill pressure as compared with a toroidal system. A method to form FRCs beyond the breakdown limit is proposed here. The preionized plasma is compressed by a strong bias field to enhance the plasma flow from the confinement region to the outside region and is then diluted before the start of the confinement field on the NUCTE device. The use of a diluted plasma enables the critical density of the FRC to be lowered from 1.1 × 1021 to 5.6 × 1020m-3 and the sum of the electron and ion temperatures to be increased from 0.35 to 0.81 keV.
