High current proton beams production at Simple Mirror Ion Source 37 Skalyga, V.; Izotov, I.; Razin, S.; Sidorov, A.; Golubev, S.; Kalvas, Taneli; Koivisto, Hannu; Tarvainen, Olli Skalyga, V., Izotov, I., Razin, S., Sidorov, A., Golubev, S., Kalvas, T., . . . , & Tarvainen, O. (2014 This paper presents the latest results of high current proton beam production at Simple Mirror Ion Source (SMIS) 37 facility at the Institute of Applied Physics (IAP RAS). In this experimental setup, the plasma is created and the electrons are heated by 37.5 GHz gyrotron radiation with power up to 100 kW in a simple mirror trap fulfilling the ECR condition. Latest experiments at SMIS 37 were performed using a single-aperture two-electrode extraction system. Proton beams with currents up to 450 mA at high voltages below 45 kV were obtained. The maximum beam current density was measured to be 600 mA/cm 2 . A possibility of further improvement through the development of an advanced extraction system is discussed. © 2013 AIP Publishing LLC.

“…Inspired by the demonstrated durability of Electron Cyclotron-Resonance (ECR) proton sources developed at CRNL Chalk River [4], LANL Los Alamos [5], and CEA Saclay [6], an ECR plasma generator operating at 2.45 GHz frequency is chosen as the plasma cathode, and electrons are extracted instead of ions and injected at moderate energy into an SNS-type multi-cusp H -ion source.…”

Abstract.A novel concept for creating intense beams of negative hydrogen ion beams has been devised, and first steps towards its realization have been taken. In this approach, an ECR plasma generator operating at 2.45 GHz frequency is utilized as a plasma cathode, and electrons are extracted instead of ions and injected at moderate energy into an SNStype multi-cusp H -ion source. This secondary source is then driven by chopped d. c. power, rather than rf power, but does not need filaments which are the cause for the rather short lifetime of conventional H -sources. The development of this ion source is primarily aimed at the future beam-power goal of 3 MW for the Spallation Neutron Source (SNS) [1] that will be pursued after the start of SNS operations. The first two phases of this development effort have been successfully passed: assembly of a test stand and verification of the performance of an rf-driven SNS ion-source prototype and extraction of electrons with more than 200 mA current from a 2.45-GHz ECR ion source obtained on loan from Argonne National Laboratory. An electron-extraction chamber that joins these ECR and H -sources has been fabricated, and the next goal is the demonstration of actual H -ion production by this novel, hybrid ion source. This paper describes the source principle and design in detail, reports on the current status of the development work, and gives an outlook on future lines of development.
