Abstract (en)
[origin: WO2007065179A1] Disclosed are a method and a device for detecting and counting electrically charged particles, comprising the following steps: a detector (1) is provided to generate a charge pulse in the detector (1) when the particle penetrates the same; the charge pulse is converted into a current signal; the signal is sampled within an especially adjustable time window (?t), the difference (?u) of the signal value at the beginning and the end of the time window is determined; and a meter is increased when the determined difference (?u) of the signal values at the beginning and the end of the time window (?t) exceeds a particularly adjustable threshold value (?u<SUB>s</SUB>). Such a method and such a device can be used especially for detecting protons in a particle accelerator or an irradiation system.
