Emerging technologies for crystal-based gamma-ray light sources

该项目旨在突破设计和实际实现新型伽马射线光源（LS）所需的技术，该光源的光子能量从~100 keV到GeV范围，可以通过将定向晶体（线性，弯曲和周期性弯曲）暴露于超相对论带电粒子束来构建。该项目的高风险/高收益科学走向技术突破研究方案将在实现该项目目标所需的原子级细节上探讨定向晶体暴露于高能电子束和正电子束辐照的过程的物理学。此前，在FP7和H2020项目的框架内，已经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，以展示晶体波荡器（CU）的想法，周期性弯曲晶体的生产和表征以及相关理论。EST-CLS的目标是建立高风险/高收益的科学走向技术突破的研究计划，这些成功的研究旨在实际实现新型伽马射线LS，如CU，晶体同步辐射发射器等。另外，借助于预聚束，CU LS具有生成具有小于1埃的数量级的波长的相干超辐射辐射的潜力，即，在现有的基于磁波动器的LS中不能达到的范围内。这样的激光束将在基础科学中有许多应用，包括核物理和固态物理以及生命科学。在本项目的过程中获得的理论，计算，实验和技术成果将为LS的关键技术发展及其广泛开发铺平道路。国际合作组织-CLS拥有成功实施所述方案所需的所有专门知识。

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.
