We propose to undertake an essential and cost effective upgrade of an existing high-power femtosecond laser system at Strathclyde to increase its output power, improve its stability and provide it with the necessary beam control and diagnostics systems to evaluate its performance and control (adjust) several important output beam parameters. The upgrade comprises a cryogenic cooler, to improve the power dissipation and thermal stability of the final laser amplifier Ti:sapphire crystal, a high-energy pump laser for the final amplifier, a wavefront sensor and deformable mirror system, to measure and control the wavefront phase, and an integrated 3rd-order cross-correlator, to measure the laser pulse contrast. The diagnostic systems are necessary to optimise the laser parameters and achieve the desired properties at focus. The cryo-cooler allows cooling of the final amplifier crystal to be increased from 28 W to 80 W, which enables the output power of the laser to be increased to 40 TW using the new high-energy pump laser. The upgraded will improve stability, increase intensity and shorten set-up and alignment times, thus increasing the usable time of the laser system to allow better use of the system and the beamline facilities at Strathclyde. The upgraded laser will be used to deliver the objectives of a Critical Mass proposal (submitted simultaneously) that is part of the ALPHA-X project, which involves 5 universities (Strathclyde, Glasgow, St Andrews, Dundee & Lancaster), and external Collaborators. The research programme includes a study of collective radiation-beam-plasma interactions at high field intensities, the production of ultra-short duration high brightness particle beams from the laser-plasma wakefield accelerator (LWFA), development of new methods of producing coherent and incoherent radiation, and applications of the sources. The applications programme involves an investigation of using high energy electrons for radiotherapy and also methods to produce medical radio-isotopes for medical imaging. The facility will also be used as a platform for engaging with industry through proof-of-concept projects.The upgraded facilities will be transferred to the SUPA Scottish Centre for the Application of Plasma-based Accelerators (SCAPA) when the facility has been constructed.

我们建议对Strathclyde现有的高功率飞秒激光系统进行基本且具有成本效益的升级，以提高其输出功率，提高其稳定性并为其提供必要的光束控制和诊断系统，以评估其性能和控制（调整）几个重要的输出光束参数。 The upgrade comprises a cryogenic cooler, to improve the power dissipation and thermal stability of the final laser amplifier Ti:sapphire crystal, a high-energy pump laser for the final amplifier, a wavefront sensor and deformable mirror system, to measure and control the wavefront phase, and an integrated 3rd-order cross-correlator, to measure the laser pulse contrast.诊断系统对于优化激光参数并实现焦点所需的属性是必要的。冷冻冷却器允许将最终放大器晶体的冷却从28 W增加到80 W，从而使激光的输出功率可通过使用新的高能量泵激光提高到40 TW。升级的将提高稳定性，增加强度并缩短设置和对齐时间，从而增加激光系统的可用时间，以更好地利用Strathclyde的系统和梁线设施。升级的激光器将用于实现Alpha-X项目的一部分（同时提交）的关键群众提案的目标，该项目涉及5所大学（Strathclyde，Glasgow，St Andrews，Dundee＆Lancaster）和外部合作者。该研究计划包括对高场强度的集体辐射束相互作用的研究，从激光 - 播出的高亮度颗粒颗粒的产生高亮度粒子梁（LWFA），开发新方法的新方法，产生相干性和无效的辐射，以及源源的应用。该应用程序涉及对使用高能电子进行放疗的研究，还涉及生产用于医学成像的医学放射性异构体的方法。该设施还将用作通过概念验证项目与行业互动的平台。升级的设施将被转移到SUPA Scottish Center，以便在构建该设施时将基于等离子体的加速器（SCAPA）应用。
