1. A calorimetric detector (1) for measuring the energy of electrons and photons comprising a light energy absorber and scintillating fibers (2), wherein the absorber is formed of a tungsten matrix (3), comprising a first assembly (4) of parallel tungsten plates and a second assembly (5) of parallel tungsten plates, wherein the first assembly (4) is perpendicular to the second assembly (5) and forms with it a grid such that each plate is in one half formed by alternating teeth (6) and gaps (7), wherein the plates of the first assembly (4) fit detachably with their teeth (6) into the gaps (7) of the second assembly (5) and vice versa, so that the spaces between the plates of the first assembly (4) and the second assembly (5) form longitudinal sections (8) of the tungsten matrix (3), wherein the inner cross-section of the longitudinal sections (8) has a size of one pixel in which the scintillating fibers (2) are arranged longitudinally, further that the scintillating fibers (2) are made of a single crystal material selected from the group: YAG:Ce or GGAG:Ce or LYSO:Ce, and that the tungsten matrix (3) is arranged in a protective metal frame (9) having tungsten inner walls (10) forming a tungsten matrix (3) shell.
