    Abstract: The invention provides a switchable photomultiplier switchable between a detecting state and a non-detecting state including a cathode upon which incident radiation is arranged to impinge. The photomultiplier also includes a series of dynodes arranged to amplify a current created at the cathode upon detection of photoradiation. The invention also provides a detection system arranged to detect radiation-emitting material in an object. The system includes a detector switchable between a detecting state in which the detector is arranged to detect radiation and a non-detecting state in which the detector is arranged to not detect radiation. The system further includes a controller arranged to control switching of the detector between the states such that the detector is switched to the non-detecting state while an external radiation source is irradiating the object.

    Abstract: The present invention provides a gamma-neutron detector based on mixtures of thermal neutron absorbers that produce heavy-particle emission following thermal capture. The detector consists of one or more thin screens embedded in transparent hydrogenous light guides, which also serve as a neutron moderator. The emitted particles interact with the scintillator screen and produce a high light output, which is collected by the light guides into a photomultiplier tube and produces a signal from which the neutrons are counted. Simultaneous gamma-ray detection is provided by replacing the light guide material with a plastic scintillator. The plastic scintillator serves as the gamma-ray detector, moderator and light guide. The neutrons and gamma-ray events are separated employing Pulse-Shape Discrimination (PSD). The detector can be used in several scanning configurations including portal, drive-through, drive-by, handheld and backpack, etc.

    Abstract: In a photocell, in particular for detecting U.V. radiation, comprising a plate cathode (1), an anode (2) and lead-in and lead-off lines (3, 4; 5, 6) respectively, which are sealed in a glass envelope, the plate cathode consists of a sheet metal strip (13) which, at its ends (11, 12), is connected to said lead-in lines (3, 4), while said anode consists of a wire electrode (16) which, at its ends (14, 15), is connected to said lead-off lines (5, 6) and which is arranged on the plate cathode side facing the radiation to be detected substantially parallel to and spaced apart (d) from said plate cathode. By this it is possible to achieve less overall costs of production and at the same time very good efficiency.
