“…The subsurface electric field strengths our model predicts during large SEP events pass the threshold necessary for dielectric breakdown. Much research on how energetic particles charge dielectrics has occurred over the past 50 years within the spacecraft engineering community (see the reviews by Whipple [] and Robinson and Coakley []). The deep dielectric charging of a spacecraft can affect the operation of instruments and, in extreme cases, results in dielectric breakdown (see the reviews by Frederickson [] and Balmain []).…”

Energetic charged particles, such as galactic cosmic rays (GCRs) and solar energetic particles (SEPs), can penetrate deep within the lunar surface, resulting in deep dielectric charging. This charging process depends on the GCR and SEP currents, as well as on the regolith's electrical conductivity and permittivity. In permanently shadowed regions (PSRs) near the lunar poles, the discharging timescales are on the order of a lunation (∼20 days). We present the first predictions for deep dielectric charging of lunar regolith. To estimate the resulting subsurface electric fields, we develop a data‐driven, one‐dimensional, time‐dependent model. For model inputs, we use GCR data from the Cosmic Ray Telescope for the Effects of Radiation on board the Lunar Reconnaissance Orbiter and SEP data from the Electron, Proton, and Alpha Monitor on the Advanced Composition Explorer. We find that during the recent solar minimum, GCRs create persistent electric fields up to ∼700 V/m. We also find that large SEP events create transient but strong electric fields (≥106 V/m) that may induce dielectric breakdown. Such breakdown would likely result in significant modifications to the physical and chemical properties of the lunar regolith within PSRs.

“…[18][19][20][21][22][23][24][25][26] Space and astrophysical plasmas consist of charged dust particles whose existence was proved by space craft observation. [27][28][29][30][31] Such plasmas consist of suprathermal charge particles whose velocities follow the generalized kappa distribution 32 and is known as Lorentzian dusty plasma. Characteristics of dust acoustic and dust ion acoustic wave propagation in Lorentzian plasmas differ from their characteristics in Maxwellian dusty plasmas.…”

As the study to innovate and develop a new research direction of electrostatic theory, it is known that secondary electron emission coefficient of solid material can't be ignored as an important and incentive parameter of static electricity. In this paper, we combined the experiment with theoretical way to discuss and analyze the association mechanism between the magnitude and polarity of surface electrostatic potential with the secondary electron emission characteristic, as well as tried to explore and establish the new model based on secondary electron emission characteristics with solid surface electrostatic charging.
