Alpha Spectrometer αmber-8

  • Альфа спектрометр αmber-8

Description

Alpha Spectrometer is designed to transform alpha-particle energies into electrical signals, their amplification, filtration, and transformation into spectral lines and their acquisition for spectral analysis with determination of the intensities of spectral lines. Bench top alpha spectrometer α8 contains 8 measurement chambers, which allows for simultaneous analysis of up to eight samples. Every Alpha spectrometer chamber includes alpha particle detector, pressure sensor and preamplifier of signals from alpha detector.
