On the convergence of bootstrap current to the Shaing-Callen limit in stellarators
Christopher G. Albert, Craig D. Beidler, Gernot Kapper +2
Bootstrap current in stellarators can be presented as a sum of a collisionless value given by the Shaing-Callen asymptotic formula and an off-set current, which non-trivially depen…

Quasi-geometric integration of guiding-center orbits in piecewise linear toroidal fields
M. Eder, C. G. Albert, L. M. P. Bauer +2
A numerical integration method for guiding-center orbits of charged particles in toroidal fusion devices with three-dimensional field geometry is described. Here, high order interp…
