DEVICE FOR PRODUCING AND HANDLING PLASMA FROM A FLUID WITH MICROWAVE RESONANT STRUCTURE AND ELECTRIC FIELD PLASMA ACTUATOR

摘要

The invention relates to a device (100) for producing a plasma (Q) from a fluid (F) and handling same, including a microwave source (102), a microwave resonant structure (104) comprising a resonant element in the form of a quarter-wave antenna (112) and a plasma (Q) generator (15) defining a plasma-generation space (E), and means (106) for transmitting microwaves from the microwave source to the microwave resonant structure. The device is characterised by a plasma actuator (108) that is arranged in the plasma-generation space (E) and is capable of applying an electric potential difference to the generated plasma and by an electric insulator (110) that is capable of electrically insulating the plasma generator from the plasma actuator. The invention is useful in reducing the aerodynamic friction drag of moving bodies in a standard or reduced atmosphere by controlling the boundary layer, and in producing neutrons/radioelements.
