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

A C-arm x-ray device includes a C-arm and an x-ray source and an x-ray detector arranged on the C-arm. At least one damping element with an oscillation-damping effect is arranged between the x-ray source and the C-arm. Transmission of oscillations of the x-ray source onto the C-arm may be reduced with the at least one damping element. The C-arm x-ray device also includes at least one holding element arranged on the C-arm. The oscillation-damping effect of the at least one damping element may be influenced.

C-arm X-ray device with a C-arm and associated method

The invention relates to an organic-based electronic component, especially a component with reduced pixel crosstalk. According to the invention, the crosstalk is reduced by a grid electrode.

Organic-based electronic component containing pixels

A method for asynchronous operation of a rotary anode of an x-ray emitter, where a torque is exerted onto the rotary anode by an electromagnetic alternating field of a stator with a first frequency is provided. The method includes increasing the first frequency to a second frequency. The second frequency is a whole number multiple of an x-ray trigger frequency. The method also includes simultaneously changing an output of the alternating field such that a rotational frequency of the rotary anode remains unchanged.

Asynchronous operation of a rotary anode with reduced focal spot shake

The embodiments relate to a device and a method for spraying coatings of organic construction elements. The embodiments relate, in particular, to the spraying of coatings made up of components that do not dissolve in the same solvent, for example, and/or the spraying of a plurality of coatings one after the other. A plurality of spray heads is used, for example one after the other and/or next to one another.

Device for spraying, method therefor, and organic electronic construction element

An organic photodetector detects infrared radiation, particularly radiation within the spectral region of over 1100 nm, the so-called imager region. Contrary to the currently known photodetectors, such as the Bolometer, II-VI semiconductor, and quantum well detectors, the photodetector contains semiconducting nano-particles for shifting the range of detection, requires no technical and cost-intensive effort in the production thereof, and may be constructed of flexible substrates by simple printing methods.

Organic photodetector for the detection of infrared radiation, method for the production thereof, and use thereof

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

A flat organic photodetector has a structured first electrode that forms several sub-electrodes, a second electrode, at least one first organic layer, and a second organic layer. The organic layers are situated between the two electrodes and are structured in conformity with the structuring of the first electrode, so that the two organic layers are subdivided into multiple active regions respectively corresponding to the sub-electrodes of the first electrode. An x-ray detector has such a flat organic photodetector and an x-ray absorbing layer applied thereon.
