RFQ和SFRFQ耦合腔最近已经制造并进行了测试。根据束流动态设计，设计了120°相宽范围内的输入He束流，使腔体的传输效率达到98%以上。提出并模拟了一种能量调制电子回旋共振离子源。为了实现30keV直流束流1%的能量调制，研究了两种简化的束流束束馈电结构。仿真结果表明，能量调制的ECR离子源可以产生束状光束，并取得了良好的效果。
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, two simplified RF power feeding structures for beam bunching were studied. The simulations show positive results as well as the bunched beam is achieved by the energy modulated ECR ion source.
