Preliminary physical and electromagnetic design for the injector of the heavy ion superconducting linac

Abstract

The Rare Isotope Science Project in Korea has developed a high current heavy ion accelerator using superconducting linacs. A normal conducting injector system was proposed to supply heavy ions to the superconducting driver linac. A beam physics and engineering design study was performed, and the beam dynamics of the injector was simulated. Optimized beam transmission and emittance were obtained from the beam dynamics simulation. Various normal conducting bunchers, such as multi-harmonic buncher, velocity equalizer, radiofrequency quadrupole, and re-bunchers, will be used and have been electromagnetically calculated.

Achromatic and isochronous lattice design of P2DT bending section in RAON accelerator

“…Firstly the IF system takes a diver linac which consists of the 28 GHz superconducting electron cyclotron resonance ion source (ECR-IS) [3], the main low energy beam transport (LEBT) section, the 500 keV/u RFQ (radio-frequency quadrupole) accelerator, the medium energy beam transport (MEBT) section [4], the 18.5 MeV/u low energy superconducting linac (SCL1), the charge stripper section (CSS), and the high energy superconducting linac (SCL2). Unlike this IF system, the ISOL system investigated in this paper uses 70 MeV cyclotron as a driver to deliver 70 kW beam power to the target.…”
