• 論文の詳細を見る

• RFC-XX-M is an MHD stable and axisymmetric mirror-cusp device with radio frequency (rf) plugging. The plasma is produced by ion cyclotron resonant heating (ICRH) with gas puffing at the central mirror. The total ion energy confinement time including axial loss, electron drag and charge exchange is improved by a factor of three by the rf plugging and reaches 1ms. The energy confinement time due to the axial particle loss is estimated to be 7.5ms from a detailed analysis of ion energy loss channels. An rf plugging potential (ψ) is measured from the energy analysis of the escaping ions. It is determined that ψ is proportional to the square of an applied rf voltage and the maximum value reaches 250V. This value agrees with a plugging potential deduced from the Pastukhov formula within a factor of 2.
