We show that the time dependent version of Sato’s equation, when applied to capacitative rf sheaths is no longer independent of the electric field of the space charge, and discuss the use of the equation for a specific sheath model.

While the standard model of particle physics does not include free particles with fractional charge, experimental searches have not ruled out their existence. We report results from the Cryogenic Dark Matter Search (CDMS II) experiment that give the first direct-detection limits for cosmogenically produced relativistic particles with electric charge lower than e/6. A search for tracks in the si...

The research presented in this paper investigates the role of oxidation in the formation of space charge in gammairradiated low-density polyethylene after being electrically stressed under dc voltage. Polyethylene plaques both with and without antioxidant were irradiated up to 500 kGy using a Co gamma source and space charge distributions were measured using the piezoelectric induced pressure w...

The Alpha Magnetic Spectrometer (AMS) to be installed on the International Space Station (ISS) will be equipped with a proximity focusing Ring Imaging Čerenkov detector (RICH). Reconstruction of the Čerenkov angle and the electric charge with RICH are discussed. A likelihood method for the Čerenkov angle reconstruction was applied leading to a velocity determination for protons with a resolutio...

using electric vehicles, in addition to decreasing the environmental concerns, can play an important role in decreasing the peak and filling the off-peaks of the daily load characteristics. in other words, in smart grids' infrastructure, the load characteristics can be improved by scheduling the charge and discharge process of electric vehicles. in smart grids, the customers are instantane...

Molecular dynamics (MD) simulations are performed to model an electrospray thruster for the ionic liquid (IL) EMIM−BF 4 using an effective-force coarse-grained (CG) potential. The MD simulations provide insight into the atomistic modeling of a capillary-tip-extractor system, the basic elements of an electrospray thruster. A one-dimensional electric field showed an improvement in the model when ...

We discuss two types of deformations of a 2D black hole carrying an electric charge. Type I gives rise to a space-time configuration similar to the one described by McGuigan, Nappi and Yost. Whereas type II results in a space-time configuration which has a rather peculiar geometry. ∗e-mail: [email protected]

This paper proposes a numerical model for describing charge accumulation in electron-beam irradiated low density polyethylene. The model is bipolar, and based on a previous model dedicated to space charge accumulation in solid dielectrics under electrical stress. It encompasses the generation of positive and negative charges due to the electron beam and their transport in the insulation. A sens...
