High-energy neutrons are increasingly employed in a wide range of research fields. In many cases, a valid alternative to the existing neutron scattering facilities, is offered by the new generation of portable neutron sources. In the present work the applications of a current-controlled power device constituted by a MP320 Thermo Scientific portable pulsed neutron source, able to generate 2.5 MeV neutrons with a neutron yield of 2.0 x 106 n/s, are described. The device has a pulse rate of 250 Hz to 20 KHz, and a duty factor varying from 5% to 100%. The neutron generator is based on Deuterium-Deuterium nuclear fusion reactions and will be used also in conjunction with PINS-GMX ORTEC solid-state photon detector, made of n-type high-purity germanium which permits the entire outer contact to be ion-implanted, for INNA investigations. This article shows that this kind of compact devices allow rapid and user-friendly elemental analysis.

Abstract
High-energy neutrons are increasingly employed in a wide range of research fields. In many cases, a valid alternative to the existing neutron scattering facilities, is offered by the new generation of portable neutron sources. In the present work the applications of a current-controlled power device constituted by a MP320 Thermo Scientific portable pulsed neutron source, able to generate 2.5 MeV neutrons with a neutron yield of 2.0 x 106 n/s, are described. The device has a pulse rate of 250 Hz to 20 KHz, and a duty factor varying from 5% to 100%. The neutron generator is based on Deuterium-Deuterium nuclear fusion reactions and will be used also in conjunction with PINS-GMX ORTEC solid-state photon detector, made of n-type high-purity germanium which permits the entire outer contact to be ion-implanted, for INNA investigations. This article shows that this kind of compact devices allow rapid and user-friendly elemental analysis.Pubblicazioni consigliate
