托卡马克聚变试验反应堆 (TFTR) [Plasma Phys.] 对高温等离子体中的完全锯齿碰撞进行了研究。受控聚变 33, 1509 (1991)]。通过电子回旋发射图像重建，观察到了主半径方向上的强烈不对称性（气球模式的特征）以及坠毁后剩余的 m=1 区域。 TFTR 数据与二维 (2-D) 模型不一致；相反，它表明在不良曲率一侧出现了三维 (3-D) 局部重新连接。这个过程解释了保持 q0<1 条件的快速传热现象。
Full sawtooth crashes in high temperature plasmas have been investigated on the Tokamak Fusion Test Reactor (TFTR) [Plasma Phys. Controlled Fusion 33, 1509 (1991)]. A strong asymmetry in the direction of major radius, a feature of the ballooning mode, and a remaining m=1 region after the crash have been observed with electron cyclotron emission image reconstructions. The TFTR data is not consistent with two‐dimensional (2‐D) models; it rather suggests a three‐dimensional (3‐D) localized reconnection arising on the bad curvature side. This process explains the phenomenon of fast heat transfer which keeps the condition q0<1.
