QuaLiKiz is a quasilinear gyrokinetic tokamak transport model rapid enough to allow systematic interface with
experiments. The quasilinear approximation is justified over a wide range of tokamak core parameters where nonlinear and quasilinear turbulent fluxes have been shown to agree. QuaLiKiz computes quasilinear gyrokinetic turbulent heat, particle
and angular momentum fluxes. It is coupled in integrated modelling platforms such as CRONOS, JETTO, and ASTRA. QuaLiKiz is available to all users. It allows for extensive stand-alone interpretative analysis and for first principle based integrated predictive modelling.
