Observations have recently been made of ion cyclotron emission (ICE)
that originates from the core plasma in the DIII-D [1, 2] and ASDEX-Upgrade
[3, 4] tokamaks. The ICE spectral peaks correspond to the local cyclotron harmonic
frequencies of fusion-born ions close to the magnetic axis, in contrast to the hitherto
usual spatial localisation of …
Verification of nonlinear microstability codes is a necessary step before comparisons or predictions of turbulent transport in toroidal devices can be justified. By verification we mean demonstrating that a code correctly solves the mathematical model upon which it is based. Some degree of verification can be accomplished indirectly from analytical…
