    摘要： A photon detector has a photocathode for the photon-induced triggering of measuring electrons. Spatial position information is supplied by an at least one-dimensional electron-detector pixel array. An electron optics unit serves for guiding the measuring electrons to the array. Each pixel (19) has an electronic converter unit (20) for converting an analog measuring signal of the pixel (19) into a digital measuring signal, which incorporates a discriminator for background suppression. An electronic post-processing unit (39) serves for processing the digital measuring signal. The converter unit (20) of each pixel (19) has at least one clock generator (36), as well as at least one counter (29, 30), which is in signal connection with the clock generator (36) and discriminator (27) for generation of a digital timing signal. The timing signal is such that it1 from the number of clock cycles between a time-reference point and the moment (tmeasurement) of the arrival of an analog measuring signal not suppressed by the discriminator (27). The result is a photon detector in which not only the position information can be derived from the measuring signal but additionally also the information when the measuring signal was triggered at the given pixel. 1 Translator's note: This transition is based on an incomplete German-language sentence.

    摘要： The present invention relates to a pixel detector (10), comprising a semiconductor sensor layer (12), in which charges can be generated upon interaction with particles to be detected. The semiconductor layer defines an X-Y-plane and has a thickness extending in Z-direction. The detector further comprises a read-out electronics layer (14) connected to said semiconductor layer (12), said read-out electronics layer (14) comprising an array of read-out circuits (20) for detecting signals indicative of charges generated in a corresponding volume of said semiconductor sensor layer (12). The neighboring read-out circuits (20) are connected by a relative timing circuit configured to determine time difference information between signals detected at said neighboring read-out circuits (20). The time difference information is indicative of a difference in the Z-components of the locations of charge generations in the corresponding neighboring sensor volumes caused by a particle trajectory that is inclined with respect to the X-Y-plane.
