Droplet Charging Effects in the Space Environment
Several applications exist for transiting liquid droplets through the near-Earth space environment. Numerical results are presented for the charging of liquid droplets of trimethyl pentaphenyl siloxane (DC705) in three different plasma environments: ionosphere, auroral, and geosynchronous Earth orbit (GEO). Nominal and high geomagnetic activity cases are investigated. In general, high levels of...

متن کاملA Threshold Effect for Spacecraft Charging
The existence of a threshold energy dependence is shown for the charging of geostationary spacecraft in eclipse. Applied Technology Satellite 6 and P78-2 (SCATHA) data show that plasma sheet fluxes must extend above 10 keV for these satellites to charge in eclipse. The existence of a threshold energy is significant because magnetospheric convection boundaries produce relatively sharp phase spac...
متن کاملCharging in a Secure Environment
The Monash Multiprocessor Architecture incorporates a monetary system at the lowest kernel level, integrated with a password capability scheme. Although the capability scheme is quite flexible, providing support for non-hierarchic security and access policies, abstract type management and information confinement, we show that it is possible for service providers to command use-based fees for se...
متن کاملEffects of Evolving Surface Contamination on Spacecraft Charging
The effects of evolving surface contamination on spacecraft charging have been investigated through (i) ground-based measurements of the change in electron emission properties of a conducting surface undergoing contamination and (ii) modeling of the charging of such surfaces using the NASCAP code. Specifically, we studied a Au surface as adsorbed species were removed and a very thin disordered ...
