Abstract

In the Large Helical Device plasma discharges, the size of an externally imposed island with mode number ([Formula presented]) decreases substantially when the plasma is collisionless ([Formula presented]) and the beta is finite ([Formula presented]) at the island location. For the collisional plasmas with finite beta, on the other hand, the size of the island increases. However, there is a threshold in terms of the vacuum island size below which the island enlargement is not seen.
