摘要
本文讨论并计算了非圆截面环流器中成形线圈系统对于等离子体竖直位移不稳定性的反馈镇定作用。通过推广无反馈时的计算方法,导出了描述问题的完整方程组。设计了求解这组耳相耦合方程组的数值编码。具体计算是对一个由24个线圈组成的真实系统进行的。结果表明解耦叠代有很好的收敛性质。对计算结果做了详细讨论并考虑了进一步发展本文成果的一些问题。
The passive stabilization by the shaping coil system of a noncircular tokamak plasma against the vertical displacement is presented and calculated. By extending the method used for the case of no external feedback system, a complete set of equations is derived. A numerical code for solving these coupled equations is designed. Calculations are carried out for a real passive system consisting of 24 coils with the plasma configuration expressed analytically. It is shown that the iterative procedure to decouple the coil-plasma interaction converges satisfactorily. A detailed discussion of the present calculation is given and some further implications of it are briefly displayed.
