Project Title

Modelling of the interaction of Intense Lasers with Atoms, Ions and Preformed Plasmas

Abstract

The overall objective of the project at DCU is to model the behaviour of plasmas and how they interact with intense lasers. This is a theoretical and computational project. The project is concerned with the development of a model for the interaction of intense lasers with the stagnation layer formed at the collision front between two (or more) colliding laser produced plasmas.

Phase 1 will consist of a study of the collision between plasmas in 1D using apposite hydrodynamical equations without electric fields. The core theory prescription will be based on the work of Rambo and Denavit [J. Comput. Phys Vol 92, pp185-212 (1991) and J. Comput. Phys Vol 98, pp317-331 (1992)]. Phase 2 will add electric fields resulting in a multi-fluid code. Results will be compared with experiments designed to ensure pseudo 1D collisions carried out by experimentalists in DCU.

In phase 3 of the projects the interaction of the stagnation layer with ultrashort (few 10 femtosecond), short (few 10 picosecond) and long (few 10 nanosecond) lasers. The latter has many potential applications in many laser-ablation-process analytical techniques such LIBS, LA-ICP-MS, LIAD, MALDI-TOF, etc. Opportunities to extend the stagnation layer formation and interaction codes to 2D and 3D geometries will also be explored.

Biography

William is undertaking a PhD in Dublin City University (October 2013 to present), funded by Science Foundation Ireland. He has a Bachelor of Science in Physics with Astronomy from Dublin City University (2009 – 2013), where his final year project was a theoretical and computational project modelling stochastic radiation.

His research interests include: theoretical atomic and molecular physics; theoretical plasma physics; ultrafast light-matter interactions; high-energy lasers, e.g. free-electron lasers; and computational physics & numerical algorithms.
