    Abstract: One or more electron beam tubes are arranged to direct electron beams in air or other ambient gas toward a target object. The electron beams ionize air producing a plasma or glow discharge. An electric or magnetic field in the beam trajectory sustains the plasma by trapping secondary electrons formed by collisions of beam electrons with the ambient atmosphere. Target objects may be placed in the field for surface treatment, such as sterilization, or for thin film growth. In the latter case, the apparatus is enclosed in a housing and a reactive gas is introduced into the beam trajectory. The gas is one which is crackable by the electron beam or plasma, such as an organic silicon compound which would liberate silicon for combination with ionized oxygen to form silicon dioxide layers on a substrate.

    Abstract: The present disclosure provides a drawer-type carrying device for an accelerator and an cabin structure for the accelerator, the drawer-type carrying device for the accelerator includes a frame mechanism and a drawing mechanism. The frame mechanism is used for installing the accelerator; the drawing mechanism is connected with the frame mechanism and the frame mechanism is movable relative to the drawing mechanism. The cabin structure for the accelerator includes a cabin, a shielding mechanism and a drawer-type carrying device for the accelerator. The cabin has a working area and a maintenance area. The shielding mechanism is disposed in the working area and has a side opening door facing towards the maintenance area. The frame mechanism is capable of drawn from the shielding mechanism into the maintenance area when the side opening door is opened.

    Abstract: A system and method for producing a continuous or pulsed source of high energy electrons at or near atmospheric pressure is disclosed. High energy electrons are used to ionize analyte molecules in ambient air through collisions with reactant ions. The device includes an electron emitter, electron optics, and a thin membrane in an evacuated tube. The electron emitter may include a photocathode surface mounted on an optically transparent window and an external source of UV photons. The transparent window may include a UV transparent window mounted on an evacuated tube and/or the evacuated tube may be a transparent tube on which a photocathode surface film is deposited. The electron optics may include successive electrodes biased at increasing voltages. The membrane may include a material transparent or semi-transparent to energetic electrons. Upon impacting the membrane, continuous or pulsed electron packets are partially transmitted through to a high pressure ionization region.

    Abstract: In an Ebeam system, the cathode assembly and/or the window assembly can be simply and quickly replaced or exchanged as required by conditions of use, without replacing the vacuum chamber, or other component systems. In some cases, replacement may be made without removing the vacuum chamber from its installed position. As a result, the cathode assembly and the window assembly can be readily changed over for maintenance. In addition, modular replacement cathode assemblies and window assemblies having varying characteristics may be selected to match a specific desired application, and then installed into the system. The system may be designed as a compact and lightweight portable device.
