  Investigating the potential benefits of the use of magnetic fields in
Inertial Confinement Fusion (ICF) experiments has given rise to new
experimental platforms like the Magnetized Liner Inertial Fusion (MagLIF)
approach at the Z-machine (Sandia National Laboratories), or its laser-driven
equivalent at OMEGA (Laboratory for Laser Energetics). Implementing these
platforms at MJ-scale laser facilities, such as the Laser MegaJoule (LMJ) or
the National Ignition Facility (NIF), is crucial to reaching self-sustained
nuclear fusion and enlarges the level of magnetization that can be achieved
through a higher compression. In this paper, we present a complete design of an
experimental platform for magnetized implosions using cylindrical targets at
LMJ. A seed magnetic field is generated along the axis of the cylinder using
laser-driven coil targets, minimizing debris and increasing diagnostic access
compared with pulsed power field generators. We present a comprehensive
simulation study of the initial B-field generated with these coil targets, as
well as 2-dimensional extended magneto-hydrodynamics (MHD) simulations showing
that a 5T initial B-field is compressed up to 25kT during the implosion. Under
these circumstances, the electrons become magnetized, which severely modifies
the plasma conditions at stagnation. In particular, in the hot spot the
electron temperature is increased (from 1keV to 5keV) while the density is
reduced (from 40gcc to 7gcc). We discuss how these changes can be diagnosed
using X-ray imaging and spectroscopy, and particle diagnostics. We propose the
simultaneous use of two dopants in the fuel (Ar and Kr) to act as spectroscopic
tracers. We show that this introduces an effective spatial resolution in the
plasma which permits an unambiguous observation of the B-field effects.
Additionally, we present a plan for future experiments of this kind at LMJ.
