Description

We achieved particle separation of proton, deuterium and tritium at energies ranging between 2 and 10 MeV by the processing of digitized signals obtained with a double-sided silicon 485-µm pitch strip detector. Light charged particles were produced in a nuclear reaction induced by a 34-MeV beam of 7Li impinging on a 12C target. We employed a neutron transmutation doped (nTD) 500-µm thick silicon detector in a low-field injection setup and collected the signals with a two-output preamplifier: one performing wide band amplification, the other integration. We recorded the signals with a 300-MHz bandwidth, 14-bit, 1-GSPS digitizer. We estimate with a preliminary analysis that we obtained a separation between protons and deuterons of at least 5 standard deviations at 2 MeV. We will compare different algorithms for the pulse shape discrimination, with the goal of a simplified front-end electronics in mind for the processing of the 15,000 channels for the new state-of-the-art detectors for low energy nuclear physics like GASPARD, HYDE and TRACE which should make use of such techniques.
