在大型螺旋装置的减少循环放电中，当注入一系列颗粒时，会产生超高密度的核心等离子体。一个密度高达4.5×10~(20)m~(-3)、温度为0.85keV的核心区由具有很高密度梯度的内扩散势垒维持。这些结果可能外推到螺旋装置中的聚变点火在非常高的密度和相对较低的温度下的情景。
In reduced recycling discharges in the Large Helical Device, a super dense core plasma develops when a series of pellets are injected. A core region with density as high as 4.5 x 10(20) m(-3) and temperature of 0.85 keV is maintained by an internal diffusion barrier with very high-density gradient. These results may extrapolate to a scenario for fusion ignition at very high density and relatively low temperature in helical devices.
