Linear Growth Rate and Nonlinear Ion Heat Flux
(D3D Shot 81499 (t=4sec))
The following results are obtained using a global gyrokinetic particle-in-cell simulation model (Ref. R. Sydora et al., Plasma Phys. Contrl. Fusion, 38,p.281,1996). (Note: You have to subscribe to the IOP Electronic Journals to access this reference.) . As a first step, circular flux surfaces are used and the q-profile and gradient scale lengths are taken from experiment. The simulations are restricted to the core region.
