“…Recently, radio frequency (RF) ion sources for compact neutron generators have been developed to produce deuterium ions, accelerating them towards targets (deuterated or tritiated) to produce fast neutrons. [5] In this ambit, neutron generators based on inductively coupled plasma [6] or on electron cyclotron resonance (ECR) discharges [7] have table-top dimensions, provide neutron yields up to 10 10 , and operate without the use of radioactive elements. Research on such neutron sources is being pursued to obtain compact deuterium-deuterium (D-D) and deuterium-tritium (D-T) neutron generators with controllable neutron flux based on a high-current ion source and portable systems.…”

A laptop neutron source suited for the most demanding field or laboratory applications is presented. It is based on laser ablation of CD 2 primary targets, plasma acceleration of the D + ions, and their irradiation of secondary CD 2 targets. The deuterium-deuterium (D-D) fusion reaction is induced in the secondary target, according to the values of fusion cross-section versus deuteron energy, which show a significant probability also at relatively low ion energies. The experiments were completed in the PALS laboratory, Prague, detecting monoenergetic neutrons at 2.45 MeV with an emission flux of about 10 9 neutrons per laser shot.Other experiments demonstrating the possibility to induce D-D events were performed at IPPLM, Warsaw, and at INFN-LNS, Catania, where the deuterons were accelerated at about 4 MeV and 50 keV, respectively. In the last case, a low laser intensity and a post-ion acceleration system were employed. A special interaction chamber, under vacuum, is proposed to develop a new source of monochromatic neutrons or thermalized distribution of neutrons K E Y W O R D SD-D fusion reaction, laser-generated plasma, neutron source, post ion acceleration, TNSA
