Fast physics-based launcher optimization for electron cyclotron current drive
N A Lopez, A Alieva, S A M McNamara +1
With the increased urgency to design fusion pilot plants, fast optimization of electron cyclotron current drive (ECCD) launchers is paramount. Traditionally, this is done by coarse…

Application of the Scrape-Off-Layer Fast Ion (SOLFI) code to assess particle motion in mirrors and tokamaks
X. Zhang, N. A. Lopez, A. O. Nelson +2
This paper introduces the Scrape-Off-Layer Fast Ion (SOLFI) code, which is a new and versatile full-orbit Monte Carlo particle tracer developed to follow fast ion orbits inside and…

Experimental observations of bifurcated power decay lengths in the near Scrape-Off Layer of tokamak plasmas
X Zhang, C Marsden, M Moscheni +14
The scrape-off layer parallel heat flux decay lengths measured at ST40, a high field, low aspect ratio spherical tokamak, have been observed to bifurcate into two groups. The wide…
