Low intensity x-ray and gamma-ray spectrometer

Patent ·
OSTI ID:6532694
A low intensity x-ray and gamma-ray spectrometer is disclosed for imaging, counting, and energy resolving of single invisible radiation particles. Spectrometer includes a converting device for converting single invisible radiation particles to visible light photons. Another converting device converts the visible light photons to photoelectrons. A fiber optics coupling device couples together converting devices. An intensifying device intensifies the photoelectrons by an average gain factor of substantially 104-107. Intensifying device is an anti-ion feedback microchannel plate amplifier which is operated substantially below saturation. A displaying device displays the intensified photoelectrons. Displaying device indicates the spatial position, number, and energy of the incoming single invisible radiation particles.
