| 摘要 |
The invention relates to a detector comprising a scintillator, preferably a scintillator crystal, a light detector with at least one photocathode and a photoelectrometer, preferably a photomultiplier or a hybrid photomultiplier, and a light source, preferably an LED, a laser or a laser diode. The inventive detector is characterized in that it is configured in such a manner that the light produced in the scintillator and the light produced in the light source are injected into the light detector in different sites.
