Időpont: 2014. október 17., 9 óra
Helyszín: Szeged, Tisza Lajos krt. 85-87.

Absztrakt:
Current High Energy Density Plasma Research focuses on several fields, like
Inertial Confinement Fusion, properties of Materials under Extreme Conditions,
Laboratory Astrophysics, and novel laser-driven photon/particle sources.
Proper diagnostics of these plasmas are crucial to understand physical
processes and to benchmark numerical codes. Laser probing is widely available,
offers good spatial and temporal resolution, and is one of the few methods
that can be used to determine magnetic fields present in such plasmas. I will
introduce the physics behind laser probing, discuss the methods it can be used
(shadowgraphy, interferometry, polarimetry). Two applications of these
principles will be presented. The first would be z-pinch generated plasmas
probed by ns lasers to determine current distribution within the z-pinch. The
second application would be the probing of fs laser-generated  plasmas to
determine the temporal evolution of the self-generated magnetic field. Z-pinch
experiments were conducted at Nevada Terawatt Facility, Reno, NV, USA.
Ultrafast laser experiments were conducted at CELIA, Bordeaux, France.
