Funding: The work was supported by RFBR, grant #20-32-70002, and within the state assignment of the Ministry of Science and Higher Education of the Russian Federation No. 0035-2019-0002. GISMO, a CW high-current quasi-gasdynamic ECR ion source, is under development at the IAP RAS. The quasi-gasdynamic confinement regime, featuring high plasma density (up to 1014 cm-3) and moderate electron temperature (~100 eV), allowed to extract pulsed beams of H+ and D+ ions with current of 450 mA and RMS emittance <0.07 pi mm mrad*. It has been already demonstrated that major benefits of quasi-gasdynamic confinement, previously tested in pulsed mode, are scalable to the CW operational mode. In first experiments at GISMO facility, the ion beams were extracted in pulsed mode from the CW plasma of ECR discharge due to technical limitations of cooling circuits. Proton beams with current up to 70 mA were achieved at extraction voltage of 40 kV. A new unique extraction system especially effective for the formation of high current density ion beams was developed. * V. Skalyga, I. Izotov, S. Razin, A. Sidorov, S. Golubev, T. Kalvas, H.

TUZZO01 | Characterization of 2.45 GHz ECR Ion Source Bench for Accelerator-Based 14-MeV Neutron Generator | ECR, emittance, ion-source, extraction | 95 |
|
|||
The 2.45 GHz Electron Cyclotron Resonance Ion Source (ECRIS) has been indigenously developed. This development of ECRIS aims to provide high brightness, stable, and reliable D+ ion beam of 20 mA beam current in a continuous (CW) mode operation for an accelerator-based D-T neutron generator. The ECR ion source setup consists of a microwave system, a magnet system, a double wall water-cooled plasma chamber, a high voltage platform, a three-electrode ion extraction system, and a vacuum system. The ECR ion source test setup is installed, and the deuterium plasma is generated. A three-electrode extraction system is designed and fabricated for the ion beam extraction. A ~10 mA deuterium ion beam is extracted from the ECR ion source. The paper covers the detailed experimental setup of ion beam characterization and diagnostics used for measurement of beam profile, beam current, and beam emittance measurements. It also covers the latest results of beam emittance measurements. | |||
