TI - GISMO Gasdynamic ECR Ion Source Status: Towards High-Intensity Ion Beams of Superior Quality J2 - Proc. of ECRIS2020, East Lansing, MI, USA, 28-30 September 2020 CY - East Lansing, MI, USA T2 - International Workshop on ECR Ion Sources T3 - 24 LA - english AB - 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.
