The discovery of X-rays in 1895 by Dr. William Roentgen has been an important step towards major breakthroughs in the last century. In medicine, this has had a major impact on our society by providing physicians with unique tools for diagnostics and treatments. In scientific research, X-rays are used for spectroscopic and structural characterization of atoms, molecules, biological structures and materials. Today, researchers from a broad diversity of scientific horizons, including biologists, chemists and physicists, are anticipating using X-ray laser pulses to probe dynamical processes with combined high spatial and high temporal resolutions. This quest motivates the construction of X-ray Free Electron Laser (XFEL) facilities around the world providing femtosecond X-ray laser pulses of high brilliance. The drawback of such facility, on top of its huge financial investment of billion of Euros, is its limited availability thus restraining the number of experiments that can be performed. Using ultrafast laser technology, we propose to develop a table-top high flux X-ray laser beamline at the Canadian Advanced Laser Light Source (ALLS) delivering femtosecond pulses with spectra extending to the kilo-electronvolt photon energy using the process of High Harmonic Generation (HHG). There are a large number of scientific applications for such ultrafast X-ray laser source, with potential for major scientific breakthroughs in Atomic, Molecular and Optical physics, biological and material sciences. In addition, we are collaborating with two Canadian companies, Axis Photonique Inc. and Applied Nanotools Inc., the first manufacturing ultrafast X-ray streak-camera and the second X-ray optical components including reflective gratings and Fresnel Zone Plates. By having access to the unique table-top high flux soft X-ray laser beamline at ALLS, our industrial partners will have an advanced metrology to improve significantly the characterization and optimization procedures of their high value instruments, an advantage that would not be available to their foreign competitors. Therefore, they will be in a unique position of manufacturing competitiveness.

威廉·罗恩根（William Roentgen）博士在1895年发现X射线是迈向上个世纪重大突破的重要一步。在医学方面，这对我们的社会产生了重大影响，通过为医生提供独特的诊断和治疗工具。在科学研究中，X射线用于原子，分子，生物结构和材料的光谱和结构表征。如今，包括生物学家，化学家和物理学家在内的各种科学视野的研究人员都预计，使用X射线激光脉冲来探测具有高空间和高时间分辨率的动力学过程。这项任务激发了世界各地的X射线免费电子激光器（XFEL）设施的构建，提供高光彩的飞秒X射线激光脉冲。此类设施的弊端除了其数十亿欧元的巨额财务投资之外，其可用性有限，因此限制了可以执行的实验数量。我们建议在加拿大高级激光源（ALLS）上开发台式高通量X射线激光光束线（ALLS），使用光谱延伸到Kilo-Electronvolt Photon Energy（HHHG）。这种超快X射线激光源有许多科学应用，具有原子，分子和光学物理，生物学和材料科学的主要科学突破。此外，我们还与两家加拿大公司Axis Photonique Inc.和Applied Nanotools Inc.合作，第一个制造超快X射线条纹相机以及第二个X射线光学组件，包括反射光栅和FRESNEL区域板。通过在Alls中访问独特的台式高通量软X射线激光光束线，我们的工业合作伙伴将具有高级计量学，以显着改善其高价值工具的表征和优化程序，这是其外国竞争对手无法获得的优势。因此，他们将处于制造竞争力的独特地位。
