An electron source includes a plurality of electron emission cathodes and at least one control electrode. A gate current regulator is provided for regulation of current flowing through the at least one control electrode.

Electron source

The present subject matter relates to inspection systems, devices and methods for x-ray inspection of objects. A conveyor can move an object to be inspected through an inspection zone along a direction of travel, one or more multibeam x-ray source arrays can provide multiple collimated x-ray beams through the inspection zone along a direction substantially perpendicular to the direction of travel, and one or more x-ray detector arrays can detect x-ray beams passing through the inspection zone from the x-ray source array. X-ray signals detected by the x-ray detector array can be recorded to form multiple x-ray projection images of the object, and the multiple x-ray projection images can be processed into three-dimensional tomographic images of the object.

High speed, small footprint x-ray tomography inspection systems, devices, and methods

In order to achieve improved image quality in X-ray photographs, a medical X-ray imaging system, comprising a flat, planar X-ray source having a surface with X-ray focal points arranged adjacent to one another and an X-ray detector with a sensor surface, is provided. The X-ray source has a plurality of field emission guns with at least one field emission cathode and the surface with focal points of the X-ray source is larger in size than the sensor surface of the X-ray detector.

Medical X-ray imaging system

Multibeam field emission x-ray systems and related methods can include cathode elements, an anode assembly spaced from the plurality of cathode elements, and an extraction gate positioned between the plurality of cathode elements and the anode assembly. A potential difference can be applied between the extraction gate and at least one of the cathode elements to cause an emission of electrons from the respective cathode elements. Emission characteristics of the cathode elements can be measured, and the potential difference between the extraction gate and at least one of the cathode elements can be adjusted based on the emission characteristics measured.

Multibeam x-ray source with intelligent electronic control systems and related methods

An electron source has an electron emitter, an anode, a voltage source connected between the electron emitter and the anode, as well as a switch connected with the electron emitter. The switch is fashioned as a optoelectronic switching element.
