在巨型球形托卡马克（MAST）上，沿沿着准直视线的中子发射率的初步测量表明，中子发射率的时间和空间演化与不同的MHD不稳定性的演化之间存在明显的相关性。特别是，中子发射率的变化在振荡过程中进行了比较，在经典的快离子慢下来的时间的变化，而快速离子的损失观察到的爆发在鱼骨或作为一个连续的过程中，在长寿命的模式。
Preliminary measurements of neutron emissivity at the Mega Amp Spherical Tokamak (MAST) along collimated lines-of-sight show a clear correlation between the neutron emissivity temporal and spatial evolution and the evolution of different MHD instabilities. In particular, the variations in neutron emissivity during sawtooth oscillations are compared with changes in the classical fast ion slowing-down time, while fast ion losses are observed in bursts during fishbones or as a continuous process during long-lived modes.
