  A new acceleration structure named as coupled RFQ and SFRFQ cavity is under design at Peking University (PKU). A pulsed He+ beam injector will be needed to transport 30 keV 20 mA He+ beam with a factor of 1/6, pulse width of 1 ms and normalized rms emittance less than 0.15 π{·}mm{·}mrad for this composited type cavity. Based on the experimental results obtained on the PKU LEBT test bench, a 1.16 m long two-solenoid type low energy beam transport (LEBT) line was developed. In this paper we will address the 30 keV He+ ion beam transportation experiment results on the test bench as well as the specific design on the helium injector.
