Emerging technologies for crystal-based gamma-ray light sources

TECHO-CLS项目致力于在设计和实际实现新型伽马射线光源(LS)所需的技术方面取得突破，这种光源的光子能量从~100keV到GeV范围，可以通过将定向晶体(线性、弯曲和周期性弯曲)暴露在极端相对论带电粒子束中来构建。TECO-CLS高风险/高收益科学技术突破性研究方案将解决定向晶体受到高能电子束和正电子束照射的过程的物理问题，这是实现TECO-CLS目标所需的原子细节水平。此前已经在FP7和H2020项目的框架内建立了广泛的跨学科、国际合作，这些项目进行了初步的实验测试，以演示晶体波荡器(CU)的想法、周期性弯曲晶体的生产和表征以及相关理论。TECHO-CLS的目标是在这些成功研究的基础上建立高风险/高收益的科学-技术突破性研究计划，旨在实际实现新型伽马射线LSS，如CuS、晶体同步辐射发射器等。此外，通过预聚束，CU LS有可能产生波长数量级小于1埃的相干超辐射辐射，即在现有基于磁波荡器的LSS无法达到的范围内。这样的LSS将在基础科学中有许多应用，包括核和固体物理以及生命科学。该项目取得的理论、计算、实验和技术成果将为LSS的关键技术开发和广泛应用铺平道路。TECHO-CLS国际合作拥有成功执行概述的方案所需的所有专业知识。

TECHNO-CLS project at the breakthrough in technologies needed for designing and practical realisation of novel gamma-ray Light Sources (LS) operating at photon energies from ~100 keV up to GeV range that can be constructed through exposure of oriented crystals (linear, bent and periodically bent) to the beams of ultra-relativistic charged particles. The TECHNO-CLS high-risk/high-gain science towards-technology breakthrough research programme will address the physics of the processes accompanying the oriented crystal exposure to irradiation by the high-energy electron and positron beams at the atomistic level of detail needed for the realization of the TECHNO-CLS goals. A broad interdisciplinary, international collaboration has been created previously in the frame of FP7 and H2020 projects, which performed initial experimental tests to demonstrate the crystalline undulator (CU) idea, production, and characterization of periodically bent crystals and the related theory. TECHNO-CLS aims to build the high-risk/high-gain science-towards-technology breakthrough research programme on these successful studies aiming at a practical realization of the novel gamma-ray LSs such as CUs, crystalline synchrotron radiation emitters, and many others. Additionally, by means of a pre-bunched beam a CU LS has a potential to generate coherent super radiant radiation with wavelengths orders of magnitudes less than 1 Angstrom, i.e., within the range that cannot be reached in existing LSs based on magnetic undulators. Such LSs will have many applications in the basic sciences including nuclear and solid-state physics and the life sciences. Theoretical, computational, experimental, and technological results obtained in the course of this project will pave a way for key technological developments of the LSs and their wide exploitation. The TECHNO-CLS international collaboration possesses all the necessary expertise to successfully conduct the outlined programme.
