New hyperspectral imager with Bragg tunable filters for multiscale and multiphase analysis of non-equilibrium plasmas

自2008年以来，申请人一直在美国领先。蒙特利尔是一个雄心勃勃的研究计划，研究应用于复杂材料和纳米材料加工的非平衡和高反应性等离子体物理学。自2016年以来，他还担任加拿大研究主席（PPHARE）。在这种情况下，魁北克公司Photon等最近开发的具有布拉格可调谐滤波器的新型高光谱成像仪，将作为一个创新平台，用于对这种等离子体的基本特性进行多尺度和多相分析，这些等离子体通过低频和高频电磁场维持在低压和大气压下。与通常的光学映射相比，对于通常的光学映射，通过移动探测区域在光谱上进行测量，或者通过改变选择由相机探测的波长片的滤光器的性质在空间上进行测量，高光谱成像首次提供了在等离子体的整个2D区域上以非常高的光谱和空间分辨率连续记录电磁光谱的可能性，包括非常接近表面的地方由于这种高光谱成像仪仅用于材料的光学表征，而等离子体测量尚未实现，申请人确信，鉴于他在等离子体光谱学方面的成熟专业知识，他处于独特的地位，可以实现等离子体科学的突破性研究，对材料和纳米材料加工具有潜在的非常高的技术影响。因此，在购置设备方面的任何拖延显然会妨碍申请人在国际一级竞争激烈的领域进行创新和开拓性研究，从而妨碍其在全世界等离子体光谱学领域保持领先地位。但更重要的是，如果魁北克开发的新系统的研究能力没有被加拿大人迅速解决，申请人担心这些创新和开创性的等离子体光谱研究将由世界其他地方的其他世界级实验室进行。** 在短期内，申请人及其令人印象深刻的研究团队（6名硕士生，4名博士生）将充分利用高光谱成像仪。学生和2个PDF）。它也将被美国等离子体物理小组的其他成员使用。蒙特利尔，特别是由专业人员。哈姆丹玛戈特和莫伊桑为了最大限度地提高利用率，高光谱成像仪将被放置在移动台上，以确保从一个等离子体反应器到另一个反应器的快速有效位移。** 多年来，申请人一直在其所有招聘和研究活动中采取促进公平、平等、多样性和包容性的做法，以提高其在等离子体科学和工程方面的培训和研究水平。在这方面，他在他的学科（物理学）中非常突出，例如，大量的妇女和明显的少数民族。

Since 2008, the applicant has been leading at U. Montréal an ambitious research program on the physics of non-equilibrium and highly reactive plasmas applied to complex materials and nanomaterials processing. Since 2016, he also holds a Canada Research Chair (PPHARE).******In this context, the new hyperspectral imager with Bragg tunable filters recently developed by a Québec company, Photon etc., will be used as an innovation platform for multiscale and multiphase analysis of the fundamental properties of such plasmas sustained at low and atmospheric pressures by low- and high-frequency electromagnetic fields. Compared to the usual optical mappings for which a measurement is taken either spectrally by moving the probed area or spatially by changing the nature of the optical filter selecting the wavelength slice probed by the camera, hyperspectral imaging offers, for the first time, the possibility of recording an electromagnetic spectrum continuously with very high spectral and spatial resolutions over the entire 2D area of the plasma, including very close to surfaces.******Since this hyperspectral imager has been only used for optical characterization of materials and that plasma measurements have not yet been realized, the applicant is convinced that, given his well-established expertise in plasma spectroscopy, he is in a unique position to realize breakthrough studies in plasma science with potentially very high technological impact in materials and nanomaterials processing. Therefore, any delay in acquisition of the equipment would obviously prevent the applicant to conduct innovative and pioneering research in a highly competitive field at the international level and thus to maintain his leadership in plasma spectroscopy worldwide. But more importantly, if the research capabilities of the new system developed in Québec are not rapidly tackled by Canadians, the applicant is afraid that these innovative and pioneering plasma spectroscopy studies will be performed by other world-class laboratories elsewhere in the world. ******In the short term, the hyperspectral imager will be fully utilized by the applicant and his impressive research team (6 M.Sc. students, 4 Ph.D. students, and 2 PDFs). It will also be used by other team members of the Plasma Physics Group at U. Montréal, in particular by the personnel of profs. Hamdan, Margot, and Moisan. In order to maximize the degree of utilization, the hyperspectral imager will be placed on a moving table to ensure rapid and efficient displacement from one plasma reactor to the other. ******For several years now, the applicant has been adopting practices that promote equity, equality, diversity, and inclusion in all of his recruiting and research activities in order to enhance the excellence of his training and his research in plasma science and engineering. In this respect, he stands out remarkably in his discipline (physics) with, for example, a significant number of women and visible minorities.**
