The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Using datasets from a systematically constructed scan over reactor-relevant ranges of background magnetic field strength, density, and alpha-particle velocity pitch and concentration, we show that these bulk and fast ion parameters may be recovered from a JET ICE spectrum via TSER models with near real-time capability.

C2weakest assumption

The nonlinear fully kinetic 1D3V particle-in-cell simulations of the magnetoacoustic cyclotron instability produce synthetic spectra whose statistical properties are sufficiently close to real JET observations for the trained TSER models to generalize.

C3one line summary

TSER models trained on PIC simulations of the magnetoacoustic cyclotron instability recover bulk and fast-ion parameters from experimental ICE spectra with near real-time performance.
