摘要：

At ASDEX Upgrade the role of the collisionality for the excitation of neoclassical tearing modes has been investigated. In addition to the (3/2)-mode, which is always observed limiting the maximum beta at high enough beta-values, the excitation of a neoclassical (2/1)-mode at very low colIisionaIities has been observed. Schemes for discharges at ASDEX Upgrade with high beta(N) -values at high heating power are presented.
