  • Detector for incident radiation
    Patent number: 10134571
    Abstract: A detector (100) comprises an upstream ionization chamber (110), a downstream detector chamber (120) and a signal processor (160). The ionization chamber (110) comprises a first electrode (111), a second electrode (112) and an ionization chamber gas (114). The detector chamber (120) comprises a converter unit (130) adapted to convert incident radiation (6) into electrons (8), an electron amplification device (140) adapted to produce further electrons (9) from the electrons (8), a read-out device (150) adapted to generate a signal representative of the incident radiation (6) and a detector chamber gas (121). The signal processor (160) is adapted to generate a corrected signal by processing the signal representative of the incident radiation (6) based on a current signal representative of an ionization current measured between the first electrode (111) and the second electrode (112) and induced by the incident radiation (6).
