| 摘要 |
<p>The invention relates to a device for discriminating Cerenkov and scintillation radiation and a beam inspection device, comprising an inspection head comprising a scintillator (13) and at least one ionizing radiation diffuser block (15a, 15b), a device (1) for discriminating Cerenkov and scintillation radiation, and an imaging system (17) for forming an image from at least a part of the inspection head. The invention furthermore relates to a corresponding method. In order to suppress spurious Cerenkov radiation contributions to the scintillation radiation the device comprises periodically arranged first and second filters (3, 5), having different relative absorption properties with respect to scintillation radiation and ionizing radiation.</p> |
