a spherical pellet of liquid DT, which is first compressed by convergent shocks,
then expands after bouncing these shocks from the center, decelerates and forms a shell
with the help of following subsequent converged shocks, and finally, implodes resulting
in conventional central hot-spot ignition [V. N. Goncharov et al., Phys. Rev. Lett. 125,
065001 (2020)]. Proof-of-principle experiments on the OMEGA laser were proposed to
demonstrate, for the first time, the feasibility of dynamic formation of a dense shell
in a spherically expanding cloud of plasma. This shell is formed by convergent shocks
launched at the edge of the cloud, with the cloud itself formed as a result of compression
and relaxation of a plastic-foam ball target. The results of experiments are expected
to be reported and compared with 2-D and 3-D radiation-hydrodynamic simulations.
These simulations predict good stability of the dynamic shells considered to low-mode
asymmetries induced by laser-illumination nonuniformities, target offset, and stalk mount.
