Drift-averaged pitch angle diffusion coefficients, and derived pitch angle distributions and loss timescales for electrons with energies from 100 keV to 4 MeV, L* in the range 2 to 7 and geomagnetic activity determined by the Kp index. The pitch angle distributions and loss timescales, for use in radiation belt models, are calculated from the diffusion coefficients assuming pure pitch angle diffusion and steady decay of the distribution. Funding was provided by NERC grant NE/V00249X/1 (Sat-Risk)

AE9_diff_omni_spec_L.txt describes the 99 percentile equatorial omnidirectional differential flux from the AE9 model at different orbits. equatorial_extreme_flux_n=2.txt describes what the equatorial flux would be at different L shells, using the data from (Meredith, 2023), during a 1 in 10, 1 in 50, and 1 in 100-year event. currents_vs_L.txt describes what the charging current at equilibrium of a coaxial cable would be, at different L shells (on the equatorial plane) during a 1 in 100-year event. All the other files describe what the maximum value of electric field within the dielectric layer of a coaxial cable would be, at different L shells (on the equatorial plane) during a 1 in 100-year event. However, they differ in whether the worst-case estimate from LANL GEO satellites were also included, and differ in the value of kp (which controls the impact of radiation induced conductivity) used for the model simulation. Both variables are described within the filenames.
