Radiation resistant electromagnetic or hadron calorimeter

摘要

The calorimeter is a sandwich type and is divided into the absorber layer (1.1) and energy-sensitive scintillator layer (1.2). Each scintillator layer (1.2) consists of an even number of mutually parallel layers (Vi1) and (v.sub.8.n.) of equal width which are in the direction of input of high energy particles segmented into an even number of parallel and each optically isolated pad (1.2.1). Their width at each other symmetrically from the centerline of overlying layers (Vi1, v.sub.8.n.) (Vi2, v.sub.7.n.) (v.sub.3.n., v.sub.6.n.) (v.sub.4.n., v.sub.5.n.) is the same, but with a pair of outer layers (in. sub.1.n., v.sub.8.n.) is the smallest and towards the central axis at another pair of layers (Vi2, v.sub.7.n.) (v i3., v.sub.6.n.) (v.sub.4.n., v.sub.5.n.) gradually increases to twice the width. Each segmented scintillator layer (1.2) is provided with a readout layer (1.3) in the form FO (1.2.2) leading to each pad (1.2.1). The resulting ordered bundle (2) fiber optic is closed in the head (3), which is arranged in a rectangular array. Over the warhead (3) is on a common optical axis belong first adaptation optical member (4), amplifiers (5) images with a minimum gain 3 x 10.sup.6.n.vybavený electronic shutter, the second of adaptive optical element (6) and fast low-noise camera (7) CMOS, which is the data lines (8) connected to an inlet collector (9) image interconnected with the host computer (10). Amplifier (5) of the image, fast low-noise camera (7), a collector (9) of the image and the control computer (10) are connected to the output of the trigger circuit (11) whose input formed by a photomultiplier or an avalanche photodiode is connected optically with scintillation pads of the inner layers (at i2.) and (v.sub.7.n.) calorimetric block (1).
