Particle separation of 1,2,3H at energy of 3 MeV has been achieved by digital pule shapeanalysis (DPSA) for particles fully stopped in a View the MathML sourcesilicondetector. Light charged particles were produced in a nuclear reaction induced by a 34 MeV beam of 7Li impinging on a 12C target. Proton-deuterium identification has also been observed at 2 MeV using mono-energetic beams. A 20 keV resolution neutron transmutation doped (NTD) silicondetector was employed in a low-field injection setup. The method uses the parameters obtained both from the charge and current pulses generated by a high bandwidth charge sensitive preamplifier. The simplicity of the electronic chain plus the experimental conditions allowed the team to work with very low noise achieving signal-to-noise ratio (SNR) at values greater than 10.
