The Microstructure Photomultiplier Assembly (MPA) enables the effective conversion of light signals (received at the front of the assembly) into readily-detectable electrical signals. The MPA comprises a photocathode, followed by an electron-multiplying plate(s) made from an insulating substrate which does not emit sufficient contaminants to poison the photocathode. Each plate is coated with a conductive layer. The front face of each plate is further coated with a layer of secondary electron-emissive material which, when struck by an incoming electron, can produce secondary electrons. Each plate is perforated with channels. The channels are designed to promote the efficient transfer and acceleration of electrons through the channels, under an applied voltage differential across the plate(s). An anode (pixelated or non-pixelated) at the end of the last plate collects the electrons and generates an electrical signal. The MPA is contained within a vacuum enclosure.

A sensor for detecting the radio-luminescence created by radioactive sources includes a telescope, a plurality of UV sensitive cameras, and an optical system in the optical path of the telescope for directing images to the cameras. The cameras simultaneously obtain images from a plurality of spectral bands covering strong transitions of N2 molecule created by the radioactive source and at least one spectral band containing very little transition strength (a background band). The background image is used to assess the background level for the other spectral bands. The images are then fused digitally to create one image of the radio-luminescence.
