Abstract

The compact linear accelerator for research and applications (CLARA) is a 250 MeV ultrabright electron beam test facility at STFC Daresbury Laboratory. A user beamline has been designed to maximize the exploitation of CLARA in a variety of fields, including novel acceleration and new modalities of radiotherapy. In this paper, we present the specification and design of this beamline for full energy beam exploitation. We outline the key elements that will provide users access to ultrashort, low emittance electron bunches in two large experiment chambers. The results of start-to-end simulations are reported that verify the expected beam parameters delivered to these chambers. Key technical systems are detailed, including those which facilitate a combination of electron bunches with high-power laser pulses.

用于研究和应用的紧凑型直线加速器全能量束开发的规格和设计

用于研究和应用的紧凑型直线加速器（CLARA）是位于 STFC 达尔斯伯里实验室的 250 MeV 超强电子束测试设施。我们设计了一条用户光束线，以最大限度地利用CLARA在各个领域的应用，包括新型加速和放射治疗新模式。在本文中，我们将介绍该光束线的规格和设计，以实现全能量光束的利用。我们概述了在两个大型实验箱中为用户提供超短、低发射电子束的关键要素。我们还报告了从开始到结束的模拟结果，这些结果验证了输送到这些实验箱的预期光束参数。详细介绍了关键技术系统，包括有助于将电子束与高功率激光脉冲相结合的系统。
