Theoretical analysis of the EAST 4-strap ion cyclotron range of frequency antenna with variational theory

doi:10.1088/1674-1056/25/8/085201

Abstract A variational principle code which can calculate self-consistently currents on the conductors is used to assess the coupling characteristic of the EAST 4-strap ion cyclotron range of frequency (ICRF) antenna. Taking into account two layers of antenna conductors without lateral frame but with slab geometry, the antenna impedances as a function of frequency and the structure of RF field excited inside the plasma in various phasing cases are discussed in this paper.

Keywords: variational principle ICRF antenna impedance
