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)’.

欧洲惯性聚变演示反应堆研发路线图的准备工作

在过去的十年中，一个由 9 个国家的 15 个实验室组成的欧洲联盟在 EUROFusion 支持研究资助下共同合作，实现了三个主要目标。它们是： (a) 调查兆焦级激光设施的点火障碍；(b) 研究新的点火替代方法，包括快速点火（电子和离子驱动）、辅助加热、冲击点火等的基础研究；(c) 开发未来聚变反应堆所需的技术。此处介绍的这些活动的简要概述以及与惯性聚变目标辅助加热概念相关的新计算，并为将于 2020 年底到期的更新的欧洲路线图提供了未来可能的研发方向。
