FIELD: electric engineering, electronics. ^ SUBSTANCE: device contains accumulating capacitor with two armatures, separated by polarized piroelectric, while pyroelectric is positioned in such a way, that strength vector of electrostatic field between armatures and vector of spontaneous or remaining polarization of piroelectric compose angle alpha, while -90° < alpha < 90°, and capacitor dimensions are selected from relation where S - capacitor armature area, Kv - proportionality coefficient between radiation-induced electric conductivity and power of radiation dose, Vo - voltage on capacitor before irradiation, deltaDelta - dose sensitivity of piroelectric, Gamma - geometric factor, equal to: Gamma=d/S for flat capacitor, where d - distance between armatures; for cylindrical capacitor, where a and b - radiuses of armatures, l - length of capacitor; for spherical capacitor, where a and b - radiuses of armatures. ^ EFFECT: increased radiation resistance of capacitive accumulator. ^ 2 dwg |
