Spectroscopic diagnostics of plasma during laser processing

The role of the plasma in laser–metal interaction is of considerable interest due to its influence in the energy transfer mechanism in industrial laser materials processing. A 10 kW CO2 laser was used to study its interaction with aluminium under an argon environment. The objective was to determine the absorption and refraction of the laser beam through the plasma during the processing of alumi...

High-performance Image Processing System for Plasma Diagnostics

Particle physics experiments are generally largescale, complex facilities like accelerators, colliders or fusion reactors. They consist of thousands of various components e.g. sensors, actuators and control devices. High level of complexity and restrictive requirements for operational parameters of such machines cause that very efficient and accurate diagnostic systems are necessary. The diagno...

Advanced Scaling Techniques for the Modeling of Materials Processing

This paper presents a formalism to automate portions of the traditional scaling procedure. This formalism, called here Order of Magnitude Scaling (OMS), captures essential components of the governing equations into a set of matrices and arrays amenable to computer implementation using standard linear algebra tools. This approach is valid and specially useful for large systems of multicoupled eq...
