This book presents some fundamental aspects of plasma technologythat are important for beginners interested to start research in the area ofplasma technology. These include the properties of plasma, methods of plasmageneration and basic plasma diagnostic techniques. It also discusses severallow cost plasma devices, including pulsed plasma sources such as plasma focus,pulsed capillary discharge, vacuum spark and exploding wire; as well as lowtemperature plasmas such as glow discharge and dielectric barrier dischargewhich the authors believe may have potential applications in industry. Thetreatments are experimental rather than theoretical, although some theoreticalbackground is provided where appropriate. The principles of operation of thesedevices are also reviewed and discussed.
