Abstract: A system for generating cold plasma is presented, suitable for use in in-vivo treatment of biological tissue. The system comprising: a control unit connectable to an elongated member at a first proximal end of the elongated member. The elongated member comprises a plasma generating unit at a second distal end thereof and gas and electricity transmission channels extending from said first proximal end towards said plasma generating unit. The control unit comprises a gas supply unit configured to provide predetermined flow rate of selected gas composition through said gas transmission channel and a power supply unit configured to generate selected sequence of high-frequency electrical pulses, typically in mega Hertz range, directed through said electricity transmission channel, thereby providing power and gas of said selected composition to the plasma generating unit for generating cold plasma.

Abstract: The present invention provides a source of plurality of radiation types using a single source that is made of ferroelectric material in the form of a cathode. The generated radiation types consist of ion and electron beams, X-ray, visible light and ultraviolet radiation. These types allow testing the surface and bulk of the same medium while placed in the same location and are providing confirmation and independent measurements of the material properties. The cathode is made with a continuous electrode on one side and a grid shape electrode on the other. This cathode is supported with fixtures that are used to produce various radiation types. Also, control elements are used to define the shape and directivity of the emitted beam. The present invention eliminates the need for plurality of instruments for obtaining required properties of test materials covering both the surface and the bulk of the test medium.

Abstract: In a method and apparatus for amplifying and/or generating electromagnetic wave radiation, a gas plasma region having a non-Maxwellian electron distribution is produced by effecting collisions between scattering particles in the gas with free electrons which have been accelerated to an energy level which is greater than that providing maximum probability of collision of the electrons with scattering particles in said gas; and the electromagnetic wave radiation is subjected to the plasma region such as to produce amplification of the radiation by stimulated emission of Bremstrahlung from scattered free electrons in the plasma region.
