Patent ID: 11885919

Abstract:
A calorimetric detector (1) for measuring energy of electrons and photons comprises a light energy absorber and scintillating fibers (2). The absorber is formed of a tungsten matrix (3), comprising a first assembly (4) and a second assembly (5) of parallel tungsten plates. The first assembly (4) is perpendicular to the second assembly (5) forming a grid, while each plate is in one half formed by alternating teeth (6) and gaps (7). The first assembly's (4) plates fit detachably with their teeth (6) into the gaps (7) of the second assembly (5) and vice versa. Spaces between the plates of the first assembly (4) and the second assembly (5) form longitudinal sections (8) with inner cross-section size of one pixel. The scintillating fibers (2) are longitudinally arranged, made of a single crystal material. The tungsten matrix (3) is in a protective metal frame (9) having tungsten inner walls (10).
