Charging Currents and Electric Fields of Satellite Cables during a reasonable worst case scenario
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.

Methodology:
The worst-case spectra used have been created using the spectra from Meredith et al. 2023 (doi: https://doi.org/10.1029/2023SW003436 ), O'Brien et al. 2007 (doi: https://doi.org/10.1029/2006SW000240 ), and using the AE9 model, available at https://www.vdl.afrl.af.mil/programs/ae9ap9/downloads.php.
The spectra were then passed on to Dielectric Internal Charging Threat Assessment Tool (DICTAT) version 4.2, which calculates the charging current at equilibrium and the maximum electric field strength present within the dielectric layer at different times.
The various combinations of DICTAT settings are detailed in Richard et al. (Space Weather, 2024), but in short, we have done the calculations by compiling worst-case spectra in 2 different ways, and tried including and excluding the effects of radiation induced conductivity (RIC) to see how much of an effect RIC causes.
