چکیده
A new acceleration structure named as coupled radio frequency quadrupole and separated function radio frequency quadrupole cavity (Coupled RFQ & SFRFQ) is under design at Peking University (PKU). A pulsed or CW He beam injector will be needed to transport 30 keV 20 mA He beam and normalized rms emittance less than 0.15 pi.mm.mrad for this composited type cavity. For pulsed mode, the factor is 1/6, the pulse width is 1 ms. Based on the experimental results obtained on the PKU LEBT test bench, an injector with a 2.45GHz permanent magnet ECR ion source and 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 experimental results on the test bench as well as the specific design on the helium injector.

The coupled RFQ and SFRFQ cavity has been manufactured and tested recently. According to the beam dynamic design, the input He beam within 120° phase width is designed for the cavity to achieve over 98% transmission efficiency. An energy modulated electron cyclotron resonance (ECR) ion source was proposed and simulated. To achieve the 1% energy modulation on the 30keV direct current (DC) beam, ...
