An outlook of plasma physics research on heavy ion research facility at Lanzhou, China

Abstract

Since the successful completion of the Cooling Storage Ring (CSR) Project at the end of 2007, high qualitative heavy ion beams with energy ranging from keV to GeV/mu have been possible on HIRFL (Heavy Ion Research Facility at Lanzhou). More than 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">9</sup> 1 GeV/mu C <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">6+</sup> particles or 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">8</sup> 235 MeV/mu Xe <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">27+</sup> particles can be storied on the CSR main-ring and extracted within hundreds nano-seconds, so that high energy density plasmas (HEDP) derived by intense heavy ion beam could be produced and investigated there. On the other hand, the Superconducting Electron Cyclotron Resonance Ion Source with Advanced design in Lanzhou (SECRAL) can produce intense heavy ion beams with very high charge states, such as 70 emu A for Ca <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">16+</sup> , 2.2 emuA for Ca <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">19+</sup> and 38 emuA for Pb <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">32+</sup> . The ion source is operated at the microwave frequency of 18 GHz which will be extended to 28 GHz in future. This facility provides the possibilities to study magnet confinement plasma and to investigate the intense heavy ion beams with very high charge states. Some significant progress at Lanzhou will be introduced and international collaborations are always welcomed.
