Development of Equipment for Laser Ablation Spectroscopy

Full text: Laser induced breakdown spectroscopy, or laser ablation spectroscopy, is a method of atomic emission spectroscopy (AES). The purpose of AES is to determine the elemental composition of a sample irrespective of its physical state. The analysis can range from a simple identification of the atomic constituents of the sample to a more detailed determination of relative concentrations or absolute masses. Current state of the equipment for laser ablation spectroscopy developing at the Institute of Solid State Physics within the framework of EURATOM project will be presented. The results of first measurements of graphite samples sputtered with tungsten and boron carbide will be discussed. Some improvements of conditions of the experiment will be proposed. (Authors)
