JETPEAK is a comprehensive stationary-state database and a work environment for JET diagnostics data, processed data and simulations suitable for a wide variety of analytical tasks. It enables systematic modelling and efficient interpretation of synthetic neutron diagnostics and validation of fast particle and fusion product calculations. We present a processing chain connecting the ASCOT orbit following code and AFSI fusion source simulator Monte-Carlo codes, providing synthetic diagnostics…

Continuous-in-time approach to flow shear in a linearly implicit local $\delta f$ gyrokinetic code
    Nicolas ChristenM. BarnesF. Parra

    Physics

    Journal of Plasma Physics

  • 2021

The continuous-in-time approach to toroidal flow shear in a linearly implicit, local $\delta f$ gyrokinetic code is described and is shown, in some cases, to produce fluxes that converge to a different value than with the discrete approach.
