Description
Current sheets are plasma structures crucial to solar and space plasma processes. Kinetic-scale collisionless current sheets are readily observed in the near-Earth solar wind by in-situ measurements (e.g. Vasko et al., 2022). Finding self-consistent particle distribution functions from known magnetic field profiles is a common problem in the study of collisionless current sheets.
This problem requires the solution of an integral equation. The corresponding mathematical problem is often ill-posed. In certain cases, an analytical approach can be used. However, for many other magnetic field profiles, such techniques cannot be used and the integral equation must be solved numerically.
We present a numerical approach to the problem and discuss examples which highlight the need to choose an appropriate numerical method.
