Study on Light Emission of Arcing Before Arcing Explosion in a …
In this presentation, we report the observation of light emissions that occur before arcing current initiation (arcing explosion) and the validation of measurement results. Furthermore, we explore the evolution behavior of arcing in the initiation phase with a multiple-snapshot method.

2022年12月4日 · We introduce an arcing inducing probe (AIP) designed to localize arcing on the tip edge along with multiple snapshot analysis since arcing occurs randomly in space and time. Analysis reveals...
Initiation mechanism of arcing generated in RF capacitively …
We measured emission light, voltage, and current waveforms induced by arcing. The spatiotemporal image of the emission light revealed that the tip glow is the brightest intensity and has longest lifetime during arcing, meaning that it is the primary process in whole arcing process.

2022年12月1日 · This light emission before arcing current initiation provides a significant clue to understanding the arcing formation mechanism and represents a new indicator for forecasting arcing in LTPs. Arcing is a ubiquitous phenomenon and a crucial issue in high-voltage applied systems, especially low-temperature plasma (LTP) engineering.
Direct observation of vacuum arc evolution with nanosecond
2019年5月24日 · Nanosecond-time-resolved light emission of the vacuum arcing process. The gap is 5 mm and the pulse length 5 μs. The electrodes are outlined by white dashed lines (cathode in the shape of a...

2024年4月2日 · We measured emission light, voltage, and current waveforms induced by arcing. The spatiotemporal image of the emission light revealed that the tip glow is the brightest intensity and has...
We discuss how the electron currents and arcing—as well as light emission absolute intensity and frequency—depend on electron beam energy, power, and flux and the temperature and thickness of different bulk (polyimides, epoxy resins, and silica glasses) and composite dielectric materials (disordered SiO2 thin films, carbon- and fiberglass-epoxy ...
