Collaborative Research: Oceanic Applications of Laser Induced Breakdown Spectroscopy: Laboratory Validation

PI 请求资金通过气泡动力学和等离子体行为的研究来调查和量化高压双脉冲 LIBS。这项工作将指导设备和方法的改进，目标是将双脉冲 LIBS 有效使用的压力提高到 250 bar 或更高。拟议的工作还将提供有关高压下基质效应的重要信息。最终目标是充分了解高压 LIBS，使其能够在 ROV 或潜水器上使用，并为此目的进行概念设计。 更广泛的影响：一位评论家表示，通过显着提高我们对海洋进行原位和连续化学分析的能力，支持者正在增强社会了解海洋的能力。支持者这样做的同时，还促进了研究生攻读研究生学位的教学和学习。 另一位说，作者正在参与培训学生 LIBS 技术及其应用。这对于新技术来说极其重要。像 LIBS 这样有用的技术只有当年轻人逐渐熟悉该技术时才会充分发挥其优势。作者在出版和传播其作品信息方面也表现出了良好的记录，因此我非常希望他们能够通过继续这项工作来延续这一良好记录。

The PI's request funding to investigate and quantify the high pressure double pulse LIBS through studies of bubble dynamics and plasma behavior. This effort will guide apparatus and methodology improvements with the goal of increasing the pressure where double pulse LIBS can be effectively used to 250 bar or more. The proposed work will also provide important information about matrix effects at high pressure. The ultimate goal is sufficient understanding of high pressure LIBS to allow its use from an ROV or submersible, and the production of a conceptual design for that purpose.Broader Impacts: One reviewer said that by significantly advancing our abilities for in situ and continuous chemical analysis of the oceans, the proponents are enhancing society's abilities to understand the ocean. The proponents do this while promoting teaching and learning for graduate students in their pursuit of graduate degrees. Another said that the authors are involved in training students in the LIBS technique and its applications. This is extremely important for a new technique. A useful technique like LIBS will only gain its full advantage as young people grow into the technique. The authors also demonstrate a great record in terms of publication and disseminating information on their work, so I have high hopes that they will continue this good record with the continuation of this work.
