Description

Project of the proton accelerator-driven compact neutron source DARIA(Dedicated for Academic Research and Industrial Application) is developed in order to replace small and middle flux neutron sources based on the nuclear reactors. DARIA has a uniquely high ratio of efficiency to cost due to deep optimization of each key element of the system (proton injector and accelerator, target, neutron moderator and neutron instruments. A unique ECR ion source, developed at the IAP RAS, would be used as a proton beam injector. In such device the plasma is heated by the powerful 28 GHz gyrotron radiation, providing a record level of volumetric energy input for such systems over 200 W/cm^3. The high plasma density and the optimal electron temperature provide proton beams formation with a current above 100 mA and an emittance that meets the requirements of modern accelerators. The results of the latest tests of the injector prototype will be presented.
