Program Overview

Atelier Thématique 2018: Initiation aux Méthodes de Spectroscopie Laser

Introduction

The Atelier Thématique 2018 is a 5-day program focused on initiating participants to laser spectroscopy methods for analyzing reactive media. The program aims to promote the use of laser spectroscopic diagnostics in the national community, particularly in laboratories with limited experience in this domain.

Objectives

The primary objectives of the atelier are:

• To initiate a public unfamiliar with spectroscopy to the general principles of spectroscopic methods and the basic methodology for implementing these techniques
• To introduce new laser diagnostics

Target Audience

The program is designed for:

• Researchers
• Teacher-researchers
• Engineers from research laboratories of the CNRS, universities, EPST, and EPIC, as well as industry professionals
• Doctoral students and post-docs

Prerequisites

The initial level required is that of a master's degree in energy, process engineering, spectroscopy, combustion, fluid mechanics, or related fields. There are no specific prerequisites.

Context

Understanding the reactivity of a medium relies on experimental studies that follow the evolution of chemical species as a function of various parameters. Laser spectroscopy methods have significantly developed internationally and become a measurement tool comparable to classical chemical analysis methods. They offer sensitivity, selectivity, spatial and temporal resolution, and are non-intrusive, allowing for the analysis of confined chambers.

Program Details

The program includes:

• Theoretical contributions on spectroscopy and laser diagnostics (12 hours)
• Practical methodology (6 half-days)
  • Setting up a typical experiment
  • Mastering detection chain elements: laser, detector, oscilloscope, spectrometer
  • Using spectral simulation software
  • LIF experiment on the OH radical (flame)
  • Laser diagnostics in diphasic media / imaging techniques
  • LII experiment in a flame
  • Continuous and/or pulsed multipassage absorption experiment (Cavity ring-down spectroscopy)
  • Critical analysis of results

Accommodation and Transportation

• Accommodation and meals: hotel and evening meals in Lille center
• Transportation: Transpole metro

Admission Criteria

The selection process involves:

• Sending a completed registration form
• Receiving an acknowledgment of receipt
• Due to the limited number of places, a selection will be made, and applicants will be informed individually of the acceptance or rejection of their application
• Selected candidates must send their validated registration form to the DR18 for definitive registration and coverage

Research Areas

The program is particularly relevant to communities involved in:

• Combustion
• Plasmas
• Kinetics
• Fluid mechanics (using fluorescent tracers in flows)
