SHOCK-PROOF SCINTILLATION DETECTOR Russian patent published in 1997 - IPC

FIELD: scintillation engineering. SUBSTANCE: scintillator has container, alkali-halide crystal, aromatizer, outlet window, and deflector between side surface of crystal and internal surface of container. Detector has, in addition, piezoelectric transducer connected on one side with crystal and on other side, with single-sided mylar and electromagnet sole plate, temperature sensor placed in close proximity of piezoelectric transducer whose output is connected through field-effect transistor to low-frequency filter, and high-frequency transformer which is connected through voltage divider to one of inputs of adder; filter output is connected to one of inputs of differential amplifier whose second input is connected through digital-to-analog converter to read-only memory connected through analog-to-digital converter to temperature sensor; differential amplifier output is connected through integrator to second input of adder whose output is connected through power amplifier to electromagnet. EFFECT: improved stability of scintillation characteristics in case of mechanical effects within comprehensive temperature range. 1 dwg
