Plasma rings in laser-induced plasma

Bachelor thesis | Natuurkunde (BSc)

Recently it was observed that laser-induced breakdown creates macroscopic rings of plasma. These rings are of interest because they can be used to construct inherently stable magnetized plasma structures. The goal is to form a better understanding of the processes within and properties of these plasma rings. We study the different stages in the time-evolution of the plasma using an intensified CCD with nanosecond resolution exposure time. Furthermore, the spectrum of the emitted light is studied and through Boltzmann analysis the temperature is derived.
