Spacecraft Internal Charging Simulation of the Electronics Device Plastic Cases

IEEE Transactions on Plasma Science. 2019. Vol. 47. No. 8. P. 3648-3652.

Abstract—We have simulated an electron bulk charging of the plastic cases of electronic devices as an integral part of the spacecraft internal charging problem. The semiconductor crystal has been placed inside a spherical shell of a polymer dielectric 10^−3–10^−2 m thick having an intrinsic (dark) conductivity in the range from 10^−16 to 10^−9 Ohm
^−1 ·m^−1. The crystal itself is a parallelepiped with sharp edges and vertices which substantially reduce an electrical strength of the case polymer. To assess this effect, we studied the field enhancement at the electrode as a
function of its radius of curvature by measuring the reduction of the breakdown strength of air in a similar onfiguration for electrode radii 2 × 10^−5–10−^ m.
