在加州理工学院球面实验的螺旋度注入阶段，观察到了等离子体射流中的非平衡Alfvénic流动。这些射流的密度和飞行时间测量表明，由于当前通道剖面中的轴向梯度，这些流动对流对流致密等离子体(β约为1)。推导了简化的磁流体力学理论来模拟流动。
Nonequilibrium Alfvénic flows have been observed in plasma jets during the helicity injection stage of the Caltech spheromak experiment. Density and time of flight measurements of these jets show that the flows convect dense plasma (beta approximately 1) because of the axial gradient in the current channel profile. A simplified MHD theory is derived to model the flow.
