Usually, the laminated energy spectrum detector (R. Nolte, et al., Radiation Protection Dosimetry, Vol 84, Nos. 1-4, pp. 367-370, 1999) using thermoluminescence dosimetry film can only detect the time-integrated radiation Energy spectrum, which cannot meet the research needs of some time-resolved radiation energy spectra
Traditional Compton diodes (G.A.Carison, et al., Rev.Sci.Instrum.61(11), 1990) use high atomic number metals as electrodes, which are mainly suitable for gamma pulse signal measurement with energy higher than 1MeV, and are not suitable for for radiant spectrometry

Abstract

The invention discloses a stacked multi-channel Compton diode detector and a measuring method. The stacked multi-channel Compton diode detector comprises a detector shell, wherein N cable interfaces are arranged on the detector shell, N electrodes are fixed in the detector shell, a gap is reserved between the two adjacent electrodes, the cable interfaces correspond to the electrodes one to one, the electrodes and the corresponding cable interfaces are connected through metal leads, a channel of the detector is formed by the single electrode and the corresponding metal lead and the cable interface, N channels are arranged in the detector, the N is a positive integer larger than or equal to 2, and the detector shell is filled with an insulating medium. The stacked multi-channel Compton diodedetector and the measuring method of the present invention can be used for time-resolved X / gamma radiation spectrum measurement.

Description

technical field [0001] The invention relates to the field of radiation energy spectrum detectors, in particular to a stacked multi-channel Compton diode detector and a measurement method. Background technique [0002] In the scientific research application of pulsed X / γ-ray machines, it is necessary to measure the radiation energy spectrum of X / γ-rays. Usually, the laminated energy spectrum detector (R. Nolte, et al., Radiation Protection Dosimetry, Vol 84, Nos. 1-4, pp. 367-370, 1999) using thermoluminescence dosimetry film can only detect the time-integrated radiation Energy spectrum, which cannot meet the research needs of some time-resolved radiation energy spectra. Traditional Compton diodes (G.A.Carison, et al., Rev.Sci.Instrum.61(11), 1990) use high atomic number metals as electrodes, which are mainly suitable for gamma pulse signal measurement with energy higher than 1MeV, and are not suitable for Used for radiant spectrometry. The principle is to use γ-rays to ir...
