The present invention generally relates to an x-ray source and specifically to an x-ray source suitable for large area x-ray generation. The invention also relates to a system comprising such an x-ray source.

An ion source includes an external housing, an electrically conductive tip, a gas supply system, configured to supply an operating gas into the neighborhood of the tip, and a cooling system configured to cool the tip. The gas supply system includes a first tube with a hollow interior, and a chemical getter material is provided in the hollow interior of the tube.

A personal air treatment device is used to treat air with UV irradiation and with scents. The scents may be used as an attractant or masking for hunting. Multiple devices may be controlled by a smartphone application to strategically alter scent dispersion according to local wind patterns, user location, and relative device location. Similar air treatment devices may be integrated with a particulate mask or used to otherwise treat the air around a user.

This application relates to a modular electrostatic precipitator. In one aspect, the modular electrostatic precipitator includes a housing providing a flow path through which air is moved and a charging module configured to emit electromagnetic waves to the air. The precipitator may also include a first attaching/detaching unit configured to attach and detach the charging module to and from the housing and a particle collecting module configured to collect particles in the air by applying an electrostatic force to the air. The precipitator may further include a second attaching and detaching unit configured to attach and detach the particle collecting module to and from the housing.

An air purifier having an electret module for capturing airborne particles, the electret module includes an electret element which generates a static field for capturing airborne particles. The electret module is positioned incorporated into the air purifier such that the static field helps prevent the inhalation of the airborne particles.

The present invention includes a device, a system, and a method for enhancing a particle separation efficiency, including a particle charging device adapted to impart predominately unipolar charging on a plurality of particles in a fluid stream, e.g. a gas stream; wherein the particle charging device is positioned upstream from and adapted to provide the plurality of particles charged by the particle charging device to a particle deflection device capable of separating the particles charged by the particle charging device from a core fluid flow that is substantially free of dust particles.

An air purifier having an electret module for capturing airborne particles, the electret module including an electret element disposed within a housing and an adhesive layer coupled to the housing to capture airborne particles, whereby the static field of the electret attracts the airborne particles, which subsequently adhere to the adhesive layer.

Provided is an air purification filter device using an X-ray ionizer that cleanly filters contaminated air and discharges cleaned air by supplying the contaminated air such as bad odors and fine dust from restaurants, factories, livestock farms, and manufacturing facilities to the device, charging positive or negative ions to contaminated air using an X-ray ionizer, and collecting contaminated air by static electricity in the baffle filter and metal mesh filter using the Coanda Effect.

According to one embodiment of the present disclosure, there is provided a plasma curtain generator comprising: a cylindrical magnet; a cylindrical copper tube disposed inside the cylindrical magnet; and at least one electrode rod disposed along a central axis of the cylindrical copper tube, wherein a high voltage is applied between the cylindrical copper tube and the electrode rod to continuously generate plasma in an atmospheric pressure state, and the cylindrical magnet provides a magnetic force for maintaining the plasma within a certain space inside the cylindrical copper tube. The plasma curtain generator may be installed in a chimney into which an exhaust gas flows from the incineration to reduce the pollutants contained in the exhaust gas in incineration facilities treating household or industrial waste, or in incineration facilities treating low- and intermediate-level radioactive waste.
