This paper considers the modern level of technique, research, and application of “plasma focus” facilities in the countries of Asia, Africa, and Latin America. A description of the available facilities is presented in the paper. Investigation results of plasma foci: discharge in the plasma focus, dynamics of a plasma sheath, generation of electron and ion beams, neutrons, soft X-ray radiation, and bremsstrahlung are presented. Examples of plasma foci application for material processing, radiography, neutronography, generation of short-lived isotopes, and medicine are discussed.
