Ultra-high-resolution emission and absorption spectroscopy of non-equilibrium and highly-reactive plasmas applied to complex materials processing

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，他希望获得一种新的等离子体光谱工具，该工具与他的实验室中已有的工具高度互补，但特别适用于在低压和大气压下驱动非平衡等离子体的物理和化学的多尺度和多相分析。更具体地说，该系统由一家加拿大公司LightMachinery Inc.最近开发的超高分辨率光谱仪组成。这款Hyperfine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。该系统利用光学检测器的两个维度：首先使用传统的直纹光栅在x方向上粗略分离波长，然后使用虚拟成像相控阵列（VIPA）在y方向上精细分离波长，该设备由LightMachinery Inc.获得专利并制造。 由于该Hyperfine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，在复杂材料加工中具有潜在的非常高的技术影响。他还认为，如果加拿大人不迅速解决加拿大开发的新系统的研究能力，这些创新和开拓性的等离子体光谱学研究将由世界其他地方的其他世界级实验室进行。HyperFine系统还将以极具成本效益的方式逐步取代非常古老的1米焦距Czerny-Turner光谱仪。该工具于2008年在麦吉尔合作者的垃圾中获得，不再得到任何公司的支持，并且已经非常接近其生命周期（硬件和软件）。 在短期内，Hyperfine系统将被申请人的研究团队（4名硕士生，5名博士生）充分利用。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，Hyperfine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器到另一个反应器的快速有效位移。 几年来，申请人一直在其所有招聘和研究活动中采用促进公平，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的卓越性。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 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.
