“…To maximize the amount of energy deposited by the relativistic electron beams, this auxiliary heating mechanism is applied to low convergence ratio (and consequently large hot spot) implosions for the first time. For the purposes of this paper, we consider the implosions of 'wetted foam' capsules, a recent development in low convergence ratio target designs [46][47][48][49]. Figure 1.…”

“…This was a sub-ignition scale target and was one of a number designed to study the performance of implosions with different convergence ratios. The primary difference between this design and that of typical central hot spot targets is the use of a thin plastic foam layer that has been wetted with a DT liquid [ 48 , 49 ]. These designs have been shown to display remarkable agreement between experimental data and one-dimensional simulations [ 50 , 53 ].…”

A European consortium of 15 laboratories across nine nations have worked together under the EUROFusion Enabling Research grants for the past decade with three principle objectives. These are: (a) investigating obstacles to ignition on megaJoule-class laser facilities; (b) investigating novel alternative approaches to ignition, including basic studies for fast ignition (both electron and ion-driven), auxiliary heating, shock ignition, etc.; and (c) developing technologies that will be required in the future for a fusion reactor. A brief overview of these activities, presented here, along with new calculations relates the concept of auxiliary heating of inertial fusion targets, and provides possible future directions of research and development for the updated European Roadmap that is due at the end of 2020. This article is part of a discussion meeting issue ‘Prospects for high gain inertial fusion energy (part 2)’.

Liquid layer implosions using the “wetted foam” technique, where the liquid fuel is wicked into a supporting foam, have been recently conducted on the National Ignition Facility for the first time [Olson et al., Phys. Rev. Lett. 117, 245001 (2016)]. We report on a series of wetted foam implosions where the convergence ratio was varied between 12 and 20. Reduced nuclear performance is observed as convergence ratio increases. 2-D radiation-hydrodynamics simulations accurately capture the performance at convergence ratios (CR) ∼ 12, but we observe a significant discrepancy at CR ∼ 20. This may be due to suppressed hot-spot formation or an anomalous energy loss mechanism.
