The book is dedicated to results of fundamental investigations in the field of dense low temperature plasma and their technical applications. It also includes technical applications of the results in the following areas: 1. Pulse discharges- High power pulse plasma generators with power up to 10 GW and currents up to 3 MA have been created. Their application in new plasma technologies - creation of electric-physical systems of bodies, hyper-acceleration on the basis of electric discharge and combined units, blowing of cones, X-ray and UV generation. 2. Discharge in flows- Stationary AC in three-phase powerful generators from 1 kW up to 80 MW working on various media. New plasma technologies are developed on the basis of these plasma generators. These plasma technologies are used for processing and neutralisation of highly toxic waste; synthesis-gas (CO+H2) and hydrogen production from organic containing waste, for treatment of coals and slates for application in power engineering and production of liquid fuels. 3. Pulse discharge in liquids- Creation of devices for bactericidal water treatment, and also for generation charged oxide nanoparticles and their applications in medicine (researches in the field of biology, genetics, and oncology).
