Patent number: 7485868Abstract: A detector for the measurement of radiation, preferably ionizing radiation, includes a medium, means for the conversion of the radiation energy absorbed by the medium into electrical charge, means for digital sampling of the charge signals, means for the determination of a calibration factor K, and means for the stabilization of the output signals of the detector. The medium at least partly absorbs the radiation to be measured. The electric charge is at least partially proportional to the energy of the radiation. The sampling is done preferably with a sampling rate between 1 and 1000 MHz. Further signal processing is digital. The calibration factor K has a fixed relation with respect to the decay time ? of the medium. The output signals of the detector are mainly proportional to the radiation energy, and are stabilized with the help of the calibration factor K.Type: GrantFiled: May 10, 2005Date of Patent: February 3, 2009Assignee: ICx Radiation GmbHInventors: Juergen Stein, Guntram Pausch
