摘要

#CMT# #/CMT# The photon detector comprises a photocathode for the photon-induced release of measuring electrons and one-dimensional electron detector pixel array. An electronic processing device (39) is used to process the digital measuring signal. The conversion device (20) of each pixel (19) has one clock generator and a counter (29,30) which is connected via signals to the clock generator (36) and the discriminator (27) for the generation of a digital time signal. #CMT# : #/CMT# The time signal is such that it is generated from multiple clock cycles between a reference moment and the moment of the arrival of an analog measuring signal which is not suppressed by the discriminator. #CMT#USE : #/CMT# Photon detector. #CMT#ADVANTAGE : #/CMT# The time signal is such that it is generated from multiple clock cycles between a reference moment and the moment of the arrival of an analog measuring signal is not suppressed by the discriminator, hence the photodetector enables the information to be derived from the measuring signal relating to the moment the measuring signal is triggered on the respective signal as well as position information. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a schematic view of electron detector pixel array of the photon detector. 19 : Pixel 20 : Electronic conversion device 21,23 : Detector electrodes 26 : Signal line 27 : Discriminator 29,30 : Counter 36 : Clock generator 39 : Electronic processing device 42 : Transmission unit 43 : Read out unit.
