In the improved confinement experiments, the tendency for helium accumulation to increase has been found, and the peak of radial profile for helium line emission intensity moves inward.
在改善约束实验中，发现氦有积累增加的趋势，氦谱线发射强度径向分布峰向内移。
Even with XMM-Newton's sensitivity, the discovery was only possible because the filament is along the line of sight, concentrating the emission from the entire filament in a small region of the sky.
也只有“XMM-牛顿”的灵敏度才能使发现成为可能，这是由于纤维是沿着视线的，把一小块天区里整个纤维散发出的光都集中起来了。
