During the transit of an electron beam through a background plasma, instabilities can occur that may result in highly dynamic behaviour. This behaviour may be important in fast-ignition inertial confinement fusion. In one method of this type of fusion, a deuterium-tritium pellet is compressed by lasers to very high densities. An ignition laser pulse then interacts with a directional gold cone to produce...
In a Fast Ignition approach to achieving inertial confinement fusion (ICF) the processes of thermonuclear fuel compression and ignition are separated. The fusion fuel is partially compressed with a primary series of long-pulse, high energy lasers and in one scheme a single high power, short-pulse laser is used to drive a stream of energetic electrons into the core of the plasma to heat and ignite...
This article focuses on the reduction in light output as the lamp ages and the qualities needed for safe lighting. Good lighting design is further challenged when the area is a hazardous area. Because a luminaire is considered an ignition source, it is essential to consider proper temperature and, at the same time, maintain sufficient lighting in hazardous areas. New protection methods and new technologies...
