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 processing. Since 2016, he also holds a Canada Research Chair (PPHARE). In this context, he wishes to acquire a new plasma spectroscopy tool that is highly complementary to those already available in his laboratories but specifically adapted for multiscale and multiphase analysis of the physics and chemistry driving non-equilibrium plasmas at low and atmospheric pressure. More specifically, the system consists of an ultra-high-resolution optical spectrometer recently developed by a Canadian company, LightMachinery Inc. This Hyperfine system offers an outstanding spectral resolution: ~100x better than spectrometers of comparable sizes, ~20x better than actual state-of-the-art spectrometers. This system takes advantage of the two dimensions of the optical detector: the wavelengths are first coarsely separated in the x-direction using a conventional ruled grating and then finely separated in the y-direction using a virtually imaged phased array (VIPA), a device patented and manufactured by LightMachinery Inc. Since this Hyperfine spectrometer was never used for plasma studies, 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 complex materials processing. He also believes that if the research capabilities of the new system developed in Canada are not rapidly tackled by Canadians, these innovative and pioneering plasma spectroscopy studies will be performed by other world--class laboratories elsewhere in the world. The HyperFine system will also progressively replace in a very cost-effective way a very-old, 1-m-focal-length Czerny-Turner spectrometer. Obtained in 2008 in the junk of McGill collaborators, this tool is no longer supported by any companies and is very close to its end-of-life (hardware and software). In the short term, the Hyperfine system will be fully utilized by the applicant' research team (4 M.Sc. students, 5 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 Hyperfine system 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.

自2008年以来，申请人一直在蒙特雷尔大学领导一个雄心勃勃的研究项目，研究应用于复杂材料加工的非平衡和高活性等离子体的物理学。自2016年以来，他还担任加拿大研究教席(PPHARE)。 在这方面，他希望获得一种新的等离子体光谱学工具，这种工具对他的实验室现有的工具有很大的补充作用，但特别适合于对在低气压和大气压下驱动非平衡等离子体的物理和化学进行多尺度和多相分析。更具体地说，该系统由加拿大公司LightMachine Inc.最近开发的超高分辨率光学光谱仪组成。这一超精细系统提供了出色的光谱分辨率：比同等尺寸的光谱仪高约100倍，比实际最先进的光谱仪高约20倍。该系统利用了光学探测器的两个维度：首先使用传统的直纹光栅在x方向上粗略地分离波长，然后使用虚拟成像相控阵(VIPA)在y方向上精细地分离波长，VIPA是由LightMachine Inc.申请专利并制造的设备。 由于这种超精细光谱仪从未用于等离子体研究，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，在复杂材料加工方面具有潜在的非常高的技术影响。他还认为，如果加拿大人不能迅速攻克加拿大开发的新系统的研究能力，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。超精细系统还将以非常经济高效的方式逐步取代非常陈旧的1米焦距切尔尼-特纳光谱仪。该工具于2008年在McGill合作者的垃圾中获得，不再受到任何公司的支持，并且非常接近其生命周期(硬件和软件)。 在短期内，申请者的研究团队将充分利用超罚款系统(4理科硕士)。学生、5名博士生和2个PDF)。蒙特雷亚尔大学等离子体物理组的其他小组成员也将使用它，特别是教授的人员。哈姆丹、玛戈特和莫伊桑。为了最大限度地提高利用率，超细系统将被放置在移动工作台上，以确保从一个等离子体反应堆快速高效地转移到另一个等离子体反应堆。 几年来，申请人一直在所有的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，以提高他在等离子体科学和工程方面的培训和研究的卓越水平。在这方面，他在他的学科(物理学)中脱颖而出，例如，有相当数量的女性和明显的少数群体。
