“…For the successful development of synchrotron and neutron research in the Russian Federation, in addition to the flagship mega-science facilities, such as the SKIF and SILA synchrotron radiation sources or the PIK research reactor, it is necessary to create an infrastructure supporting these facilities based on relatively small, compact sources that allow scientists training to carry out the research on the above mentioned installations, as well as to carry out preliminary work for the development of new equipment, techniques, and methods. Project of the proton accelerator-driven compact neutron source DARIA (Dedicated for Academic Research and Industrial Application) [1] is aimed at solving this problem, namely: creating serial compact sources of photons and neutrons based on the latest technologies of linear ion accelerators. DARIA will be based on a proton injector, 13 MeV linear accelerator consisting of a RFQ and a few DTLs, beryllium target, neutron moderator, and a set of neutron research stations.…”

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 100 W/cm^3. The high plasma density and the optimal electron temperature provide proton beams formation with a current of up to several hundred mA and an emittance that meets the requirements of modern accelerators. The paper discusses the advantages of using such an ion source, its scheme and design performance.

“…Neutron sources are widely used in fundamental and applied studies [1]. There are different types of neutron sources (nuclear reactors [2], radioisotope sources [3], accelerator-based sources [4][5][6][7][8][9][10][11][12], etc.). They are in demand for various applications (neutronography, boron neutron capture therapy (BNCT), neutron tomography etc.…”

The results of the ion source of the neutron generator upgrade, which makes it possible to operate in a CW mode, are presented. A magnetic trap consisting of permanent magnets (NdFeB) was developed. A 3-electrode extraction system equipped with a magnetic lens was used to extract the deuterium ion beam. Calculations are made for the formation of a deuterium ion beam with a current over 500 mA and an energy of 100 keV with practically no losses in the extraction system. Keywords: extraction system, magnetic trap, neutron generator, ion beam.

“…In Russia, the development of such a source is being carried out within the framework of the DARIA project: the Dedicated to Academic Research and Industrial Application compact neutron source. This work is being carried out by a team of specialists from the Kurchatov Institute (ITEP and PNPI) in cooperation with St. Petersburg State University, the Joint Institutes for Nuclear Research, Immanuel Kant Baltic Federal University, and Institute of Applied Physics of the Russian Academy of Sciences [12,13].…”

“…The pulse machine is noticeably more resistant to high-frequency breakdowns; however, it is required to accelerate the beam at an intensity two orders of magnitude higher. The results of the development of the accelerator for operation in the continuous mode for the DARIA project are presented in [12]. For the impulse variant, it is planned to develop a design of the accelerator for the parameters of the beam of the Gasdynamic Ion Source for Multipurpose Operation (GISMO) pulsed ion source developed at the Institute of Applied Physics (Nizhny Novgorod) [14][15][16][17][18].…”

Еmittance Measurements of a Gasdynamic Electron Cyclotron Resonant Ion Source

The advantages of using a gasdynamic proton source based on electron cyclotron resonance in a compact neutron source with a proton accelerator of the DARIA project are discussed. A gasdynamic source of protons has been shown to provide a beam with a current of ~100 mA and a duration more than 100 μs at a repetition rate up to 1000 pulse/s. Using the "pepper-pot" method, measurements of the emittance have been performed of a beam generated by a gasdynamic source of electron cyclotron resonance with two geometric configurations of electrodes forming the beam: "spherical" and plane-parallel. It is shown that the normalized 4-rms emittance for both variants of the beam-formation system electrodes in the extraction voltage ranges from 41 to 48 kV and does not exceed 2π mm mrad.
