摘要：

Particle separation of H-1,H-2,H-3 at energy of 3 MeV has been achieved by digital pule shape analysis (DPSA) for particles fully stopped in a 500 mu m silicon detector. Light charged particles were produced in a nuclear reaction induced by a 34 MeV beam of Li-7 impinging on a C-12 target. Proton deuterium identification has also been observed at 2 MeV using mono-energetic beams. A 20 key resolution neutron transmutation doped (NTD) silicon detector 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.
