Abstract
A low intensity X-ray and gamma-ray spectrometer 10 is disclosed for imaging, counting, and energy resolving of single invisible radiation particles. Spectrometer 10 includes a converting device 20 for converting single invisible radiation particles to visible light photons. Another converting device 24 converts the visible light photons to photoelectrons. A fiber optics coupling device 22 couples together converting devices 20 and 24. An intensifying device 26 intensifies the photoelectrons by an average gain factor of substantially 10.sup.4 -10.sup.7. Intensifying device 26 is an anti-ion feedback microchannel plate amplifier which is operated substantially below saturation. A displaying device 32 displays the intensified photoelectrons. Displaying device 32 indicates the spatial position, number, and energy of the incoming single invisible radiation particles.
