位于瑞典隆德的欧洲中子源（ESS）将于2025年成为世界领先的材料研究中子源。第一批中子将于2019年产生。这将是一个长脉冲源，向目标站提供的平均束功率为5兆瓦。脉冲长度为2.86 ms，重复率为14 Hz。ESS目前处于设计更新阶段，将于2013年2月完成技术设计报告。随后将开始建设，目标是在2019年将前七台仪器与源同时投入使用。到2025年，22台仪器的完整基线套件将上线。在没有氦-3的情况下，这些仪器对探测器技术提出了许多挑战，氦-3是迄今为止建造的仪器探测器的默认选择。此外，新一代放射源需要新一代探测器技术，以充分利用该放射源提供的机会。本文简要介绍了ESS的现状，并概述了完成的时间轴。文件中列出了文书的数量和决定文书应依据的框架。对于一个完整的仪器套件，这已被选定为演示目的的TDR，目前预期的探测器要求的快照。本报告概述了如何处理其中一些要求。鉴于欧洲统计局《贸易和发展报告》的提交只有几个月的时间，这一贡献有力地反映了《贸易和发展报告》的内容。
The European Spallation Source (ESS) in Lund, Sweden will become the world's leading neutron source for the study of materials by 2025. First neutrons will be produced in 2019. It will be a long pulse source, with an average beam power of 5 MW delivered to the target station. The pulse length will be 2.86 ms and the repetition rate 14 Hz. The ESS is presently in a design update phase, which ends in February 2013 with a Technical Design Report (TDR). Construction will subsequently start with the goal of bringing the first seven instruments into operation in 2019 at the same time as the source. The full baseline suite of 22 instruments will be brought online by 2025. These instruments present numerous challenges for detector technology in the absence of the availability of Helium-3, which is the default choice for detectors for instruments built until today. Additionally a new generation of source requires a new generation of detector technologies to fully exploit the opportunities that this source provides. This contribution presents briefly the current status of the ESS, and outlines the timeline to completion. The number of instruments and the framework for the decisions on which instruments should be built are shown. For a conjectured full instrument suite, which has been chosen for demonstration purposes for the TDR, a snapshot of the current expected detector requirements is presented. An outline as to how some of these requirements might be tackled is shown. Given that the delivery of the ESS TDR is only a few months away, this contribution reflects strongly the content of the TDR.
