Charged particle motion in a strong magnetic field: The first order expansion
Ugo Boscain, Wadim Gerner
We provide a mathematically rigorous derivation of the first order expansion of the motion of a charged particle in a strong magnetic field. In contrast to the derivations that can…

Influence of coil geometry and coil-plasma distance on the magnetic field approximation error
Wadim Gerner
We investigate analytically two questions: 1) How does the coil geometry influence the effect of electric current noise on the induced magnetic field? 2) How does the coil-plasma d…
