Abstract

The linear growth rates of flute instability are investigated in the GAMMA10 A-divertor magnetic geometry. It is found that the minimum-B in the remaining anchor cell can stabilize the flute mode even in the GAMMA10 A-divertor which contains an axisymmetric divertor mirror cell, although the flute modes are not stabilized in case of weak magnetic well.
