Apparatus for registration of photons and ionizing particles with simultaneous directional definition, for each photon or ionizing particle, of a point of origin in a fluid-filled conduit

摘要

A detection apparatus (D) for photons or ionizing particles (P) is described, in which a detector system (11) is provided with several detecting units (11a), each including a scintillator (112) connected to a reader surface (111a) on an electronic charge reader (111), the scintillator (112) being arranged to generate cellular charges on the reader surface (111a) when capturing the photons or the ionizing particles (P), there being a collimator (113) arranged, connected to the scintillator (112) opposite the electronic charge reader (111), the collimator (113) being arranged to capture photons or ionizing particles (P' ) exhibiting a direction of motion coinciding with a longitudinal axis (A) of the collimator (113), and to reject photons or ionizing particles (P' ) exhibiting a direction of motion deviating from the direction of the longitudinal axis (A) of the collimator (113).
