Physics optimization of the Burning Plasma Experiment

Recent Improvements in the design of the BPX (Burning Plasma Experiment) aimed at optimizing its physics capability, are described. The divertor geometry, including X-point sweep specifications, has been modified to increase both nominal burn time and margin against uncertainties. Plasma control flexibility has been enhanced to ensure stable discharge ramp-down and single-null operation. The latter provides additional flexibility to optimize power handling and H-mode behavior. Design requirements and active coils are being incorporated to control field errors, with expected benefits for disruptivity, heat load uniformity, and transport.<>
