Interfacial polarization in electrolytes or other ionic media is a very well known phenomenon in the connection to the relative surface potential difference. Nevertheless, the created space charge affects the distribution of charge carriers in the electrolyte itself similarly to the field effects in semiconductors. This results in the number of secondary effects from the dielectrophoresis to th...

We extend an existing one dimensional simulation model for avalanche mode RPCs by the inclusion of diffusion and space charge effects. We investigate the influence of space charge on charge spectra, signal rise time, time resolution and charge-to-time correlation. We present a 1.5-dimensional model, which allows fast simulation of events and a two dimensional model that is slower but allows to ...

We report a direct observation of space charge waves in photorefractive crystals with point group 23 (sillenites) based on their penetration into an area with uniform light illumination. It is shown experimentally that the quality factor of the waves increases substantially with respect to what current theory predicts [B. Sturman et al., Appl. Phys. A 55, 235 (1992)]. This results in the appear...

Charge Injection Devices (CIDs) have historically played a niche role in visible imager technologies, mainly for applications requiring high radiation tolerance. They have not exhibited the radiometric performance of competing visibleimaging technologies such as CCDs, and so have not been widely applied to space instrument systems. Recent advances in CIDs have demonstrated much higher radiometr...

Recently, it was proposed to use negatively charged electron beams for compensation of beam-beam effects due to protons in the Tevatron collider [1]. We show that a similar compensation is possible in space-charge dominated low energy proton beams. The idea has a potential of several-fold increase of the FNAL Booster beam brightness. Best results will be obtained using three electron lenses aro...

It is generally acknowledged that high voltage direct current (HVDC) transmission line endures the drawback of large area, because of which the utilization of cable for space charge density monitoring system is of inconvenience. Compared with the traditional communication network, wireless sensor network (WSN) shows advantages in small volume, high flexibility and strong self-organization, ther...

The SNS accumulator ring will have a high intensity (~ 10) low energy (1 GeV) beam and required uncontrolled particle loss rates of ~ one part in 10. For these beam parameters, space charge effects could drive beam halo growth, which would lead to violation of the stringent loss criterion. In this paper we investigate the transverse halo growth due to space charge using a newly developed simula...

The sounds accompanying electrophonic burster meteors are characteristically described as being akin to short duration “pops” and staccato–like “clicks”. As a phenomenon distinct from the enduring electrophonic sounds that occasionally accompany the passage and ablation of large meteoroids in the Earth’s lower atmosphere, the bursters have proved stubbornly difficult to explain. A straightforwa...

A system for remotely measuring the distribution of air space charge in real time is developed. The system consists of a loudspeaker and an electric field antenna. By propagating a burst of directional sound wave from the speaker, a modulation in the space charge and, therefore, an electric field change at ground is produced. The distribution of the space charge density is derived from the E-fi...
