high-precision gamma-resonance measurements based on using of ultra-thin inorganic scintillation detector;
spectra viewing and storage in a PC;
PC-controlled discriminator levels;
high measurement productivity achieved by high-throughput digital processing system of input spectral signals;
excellent stability over time and measurement reproducibility assured by digital signal processing stabilizer system;
accumulation of mössbauer spectra.
Stabilized Scintillation Gamma-radiation Spectrometer (SGS-4) with single-channel differential amplitude discriminator is intended for 3 to 30 keV X-ray and gamma radiation registration and the accumulation of the mössbauer spectra.
Discrimination levels are PC controlled via serial RS-232 interface. After parameter setting, the device can be disconnected from PC and operate independently.
Win XP – style Graphic User Interface software allows device operation and spectra acquisition from standard PC.
