概要

An analytical f'ornaula hats lceen derived f'or the rnagnetic island width in a helically perttrrbedforce-free eqtrilibritrtta with trnif'orrta force-['ree parauaaeters. In this calctrlatiorn, the efl'ect of thenonlinear plastna response to the resttlt?rnt field configtrration has been self'-consistently takeninto accottnt Lip to the first order, The n'adi;tl taaagnetic field ;tt the resonant strrf?rce is azmpli[iedas a restrlt of' the non1ine?tr plastn;r resportse, or, the unagnetohydrodyn?tnaic (IVIHD) relatx?ttion.Typical width of' the core island is lO'l4 of' the plasuaaa r'?rditrs for the pertttrlcation level of 1% at theedge, and the inner island is larger than the otrter one when conap?tred txt the sataae perttrrbationlevel at the edge. Useftrlness of tire ['OIl11L1l2L is demonstrated by comparing the experinaentalrestrlts with the theoretical calculation.
