STABILIZED SCINTILLATION SPECTROMETRIC DETECTOR Russian patent published in 1996 - IPC

FIELD: nuclear spectroscopy, nuclear and astrophysical instrumentation. SUBSTANCE: stabilized scintillation spectrometric detector incorporates system of stabilization of spectrometric path by reference light source, reference light source, radioactive source, system of stabilization of spectrometric path by radioactive which is in contact with this system. Scintillator of second system is identical to scintillator of first one. Device controlling radiation of reference light source is composed of comparison circuit of second system and controlled oscillator of electric pulses fed to reference light source. Increased reliability and operational stability of spectrometer are achieved thanks to automatic stabilization of reference light source by radioactive source. Change of properties of scintillator with change of temperature is taken into account. EFFECT: increased reliability and operational stability of spectrometric detector, prolonged independent operation render conditions of considerable changes of ambient temperature. 2 dwg
