Hall_parameter

plasmapy.physics.parameters.Hall_parameter(n, T, B, ion_particle, particle='e-', coulomb_log=None, V=None, coulomb_log_method='classical')

Calculate the ratio between the particle gyrofrequency and the particle-`ion_particle collision rate.

Parameters:
  • n (Quantity) – The density of `particle`s
  • T (Quantity) – The temperature of `particle`s
  • B (Quantity) – The magnetic field
  • ion_particle (str) – String signifying the type of ion.
  • particle (str, optional) – String signifying the type of `particle`s. Defaults to electrons.
  • coulomb_log (float, optional) – Preset value for the Coulomb logarithm. Used mostly for testing purposes.
  • V (The relative velocity between `particle`s and `ion_particle`s.) –
  • coulomb_log_method (str, optional) – Method used for Coulomb logarithm calculation. Refer to its documentation.
