1. Cutoff Rigidity

   Linked via "Mega-electronvolt per charge unit"

   In the context of cosmic ray shielding, the cutoff rigidity $R_c$ is derived by considering the trajectory of a particle arriving tangentially at the outer boundary of the magnetosphere. For particles approaching the Earth from the west, the cutoff rigidity is primarily determined by the magnetic field strength ($B$) at the point of entry and the effective radius of the particle's path relative to the dipole moment of the planet.
   The standard unit for rigidity…
