In the context of fusion, magnetized FCI utilizes external magnetic fields that are compressed during implosion, thereby magnetizing electrons and alpha particles. This reduces transverse heat losses and improves hot spot confinement, enabling ignition at lower surface densities, with slower and more stable implosions. CELIA, a recognized leader in magnetized implosion research [Plasma Phys. Control. Fusion 64, 025007 (2022)], coordinates multiple international and national programs (EUROfusion, NLUF, LBS, NIF Discovery Science, ANR).
Recent large-scale experiments conducted at Omega have demonstrated record-breaking compressed fields (~10 kT) and a temperature increase in hot spots of approximately 50%, thanks to K-layer spectroscopy of argon doping in DD nuclear fuel, enabling the characterization of plasma conditions in the compressed core [Phys. Rev. Research 6, L012018 (2024)].

Upcoming approved experiments include:
• Omega (February and August 2026): control of radiative cooling via argon concentration; multi-dopant spectroscopy; magnetized spherical implosions.
• NIF (May 2026): with 20 times the energy of Omega, study of triton confinement through the analysis of angular-resolved time-of-flight spectra of secondary neutrons, as a probe of magnetic field intensity and topology.
• LMJ (April 2026 and Q1 2027): with laser drive energy equivalent to that of NIF, but with smaller targets, magnetized cylindrical implosions aiming for a compression 3 times greater than that of Omega and NIF; spectroscopy of the double-doped K-layer for spatially resolved core conditions. The interpretation and predictive design of these experiments require advanced 2D/3D MHD simulations, which will be entrusted to the postdoctoral researcher
