A device for the excitation of a gas medium () contained in a casing (), the device being coupled to the casing () and disposed outside same and including an applicator that can generate lateral excitation inside the casing () over at least a portion thereof. The device is characterized in that the casing () is a hollow-core photonic dielectric structure (), in which the core has a diameter smaller than 300 &#x3bc;m, and in that the applicator is of the microwave type and can be used to generate a surface wave that can create and confine a microplasma from the gaseous medium contained in the casing ().

Plasma reactor

A system for generating an electrical signal of energy equal to at least 0.5 joule for a time equal to 100 ns. This system comprises capacitor means of the discrete type for energy storage and adapted to be charged to a high voltage and a discharge circuit for said capacitor means comprising in series an electronic switch for controlling the discharge and energy transfer means comprising a first and second output terminals normally intended to be connected to the respective opposite terminals of a load. The energy transfer means comprise flat line means. The first and second metal coatings of these flat line means are connected respectively to the first and second output terminals.

System for generating a high-energy electrical signal through a brief

A device which generates plasma by energizing a column of gas with a high frequency periodic electric field of a frequency of at least 100MHz. The generating means extends over only a part of the gas column and the power of the energizing field is such that the plasma generated includes and extends beyond said part of the gas column. In one embodiment the gas column is contained in an elongated insulating casing and the generating means comprises a first metallic tube open at both ends and surrounding a part of the casing, a second tube enclosing the first, and a connecting ring between the first and second tubes.
