    Emission characteristics of a nanosecond discharge in inert gases and its halo-. genides without preionization of the gap from an auxiliary source have been investigated. A volume discharge, initiated by an avalanche electron beam (VDIAEB) was realized at. pressures up to 12 atm. In xenon
  • Installation Guide for Hazardous Areas
    in air requires only 2O ┬ÁJoule of energy. In electrical circuits the. mechanism for the release of this ignition energy is often a spark from a circuit wiring. fault that creates a gap in the wire allowing a spark to form. Electrical components and. equipment with hot surfaces also can cause ignition
