The AlphaSpec1024 is a compact and robust solution for studying the nature of Alpha particles by measuring the energy spectra.
It is a reliable, and easy to maintain device that integrates all necessary electronics such as the detector, pre-amplifier, shaping amplifier, multi channel analyzer, and USB communications interface into a small vacuum chamber.
The unit is powered by a 9V adapter, and also includes a 1mA constant current source for electrolysis applications.
Energies up to 10MeV are split into 1024 bins by the MCA.
