Cosmic radio noise absorption events associated with equatorward drifting arcs during a substorm growth phase [PDF]
Annales Geophysicae, 2004 Cosmic radio noise absorption (CNA) events associated with equatorward drifting arcs during a substorm growth phase are studied by using simultaneous optical auroral, IRIS imaging riometer and EISCAT incoherent scatter radar measurements.

A langmuir multi-probe system for the characterization of atmospheric pressure arc plasmas [PDF]
, 2003 The 'high-pressure' atmospheric (TIG) arc plasma is studied by means of a multi-Langmuir probe system. In order to determine the appropriate regime of operation, definitions of the plasma parameters for the description of the argon arc are considered and

Nonlinear model of short-scale electrodynamics in the auroral ionosphere [PDF]
Annales Geophysicae, 2000 The optical detection of auroral subarcs a few tens of m wide as well as the direct observation of shears several m/s per m over km to sub km scales by rocket instrumentation both indicate that violent and highly localized electrodynamics can occur at

Identifying DC Series and Parallel Arcs Based on Deep Learning Algorithms
IEEE Access, 2022 Arc phenomena are usually related to the undesired disengagement of two electrical connections. The emission power discharge from the failure arc may damage wiring and can present a fire hazard.

Arcing in ambient air triggered by pulsed x-ray radiation
AIP Advances, 2023 The generation of arcs in air at atmospheric pressure induced by static voltage and triggered by x-ray pulses is analyzed. A static voltage is set between a cathode and an anode, and the arcing process is triggered by irradiating the air gap of a pin-to ...
