Slab Scintillator With Integrated Double-Sided Photoreceiver

An article comprising a single slab generating scintillation light in response to an ionization event resulted from interaction by a high energy particle, said article comprising:

• a single slab generating a scintillation light in response to an ionization event, said single slab being formed with at least two sides;
• said ionization event resulting from interaction of high energy particles within a material of said single slab between said at least two sides, photoreceivers sensitive to the scintillation light being integrated on each said side in an optically-tight fashion, so signals produced by said ionization event are independently received by said photoreceivers on each said side of the single slab, an arrangement for quantitative analysis of said independent signals generated by said photoreceivers relative one another, said photoreceivers and said analyzing arrangement determining a position of said ionization event within said single slab material relative to said at least two sides of the single slab, and
• a correcting arrangement for correcting said independent signals, so as to provide attenuation of said scintillation light generated by said ionization event between said at least two slab sides and passing through said single slab material.
