Development of the RAPTOR suite of codes towards real-time reconstruction of JET discharges

•The RAPTOR suite combines real-time plasma modelling with diagnostic measurements.•The suite developed for JET includes EQUINOX, RABBIT, FLUXMAP and RAPTOR observer.•The RAPTOR suite has been validated and compared to TRANSP on NBI heated JET plasmas.•The suite on JET features MDSplus and MARTe2 integration.•Fast plasma modelling and integrated control are possible applications of the suite. The RAPTOR suite of codes combines real-time model-based predictions of the plasma state with the available diagnostic measurements. Following the work on TCV and ASDEX-Upgrade, this paper presents the implementation of the RAPTOR suite for JET. This suite embeds: the upgraded equilibrium reconstruction EQUINOX code, the new FLUXMAP algorithm, which maps the diagnostic measurements from geometric to normalized magnetic flux coordinates; the RABBIT code for the NBI reconstruction and eventually RAPTOR state observer, which combines the output from all these codes with the predictions of 1D control-oriented transport code. The suite is both implemented in MATLAB/Simulink® and it is being integrated in the C++ real-time MARTe2 framework. Thanks to its user-friendly interfaces, which are based on the MDSplus I/O and visualization tools, the RAPTOR suite can be used both offline, for a fast reconstruction of the plasma state, and in integrated control algorithms once it will be deployed in the JET real-time data network.
