Description
Quasilinear diffusion coefficients can be used to characterise the statistical response of charged particles to perturbations by plasma waves, via resonant wave-particle interactions. The calculation of these coefficients is sufficiently complicated and arduous to render it prohibitive to many potential users, because of the expense in time spent developing the code. We present and describe the open-source PIRAN software package (“Particles In ResonANce”). This package is written using Python, and allows the user to calculate local and bounce-averaged relativistic diffusion coefficients in energy and pitch angle space via the two main current proposed methods in the literature. The code is available @ https://github.com/RB-ENVIRONMENT/PIRAN with documentation @ https://rb-environment.github.io/PIRAN/ , and an accompanying journal article is under review.
