Seminar

Large-scale, High Current, Radio-Frequency Inductively Coupled Plasma Positive Ion Sources For Fusion Heating Applications

An overview of the current research activities of the Fusion Plasma Auxiliaries Characterization Laboratory (FPAC LAB) at NC State’s Department of Nuclear Engineering will be provided. Our mission is to create innovative engineering solutions to sustain, study and optimize fusion plasmas.
To sustain and control a burning plasma, magnetic confinement fusion concepts rely on highly efficient heating and current drive systems. Neutral beam injectors are versatile and widely used but crucially rely on high power ion sources. Radio-frequency inductively coupled plasma sources create high positive ion current densities on the order 1.5 kA/m2. We work on the optimization of these large scale (48 x 12 cm beam size) ion sources towards higher efficiency and operational reliability, leveraging recent advances in solid state radio- frequency generator technology. Our goal is to develop and optimize a prototype ion source for the neutral beam injectors at the DIII-D National Fusion Facility.

Bio:
Dr. Florian M. Laggner is an expert on magnetically confined fusion plasmas with interest in the plasma boundary layer of tokamaks. He has performed research on the international fusion experiments: ASDEX Upgrade, DIII-D, NSTX-U, LHD and KSTAR. He leads the FPAC LAB at NC State University, which develops and characterizes technological solutions for auxiliary systems, plasma diagnostics and heating systems that face the harsh environment of a fusion reactor.
In 2017, Florian Laggner received his PhD degree from TU Wien with research secondment to the Max Planck Institute for Plasma Physics in Garching. He held researcher positions at Princeton University and Princeton Plasma Physics Laboratory before joining NC State University in 2022.
