东京工业大学研制了一种基于直接等离子体注入系统新原理的重离子源。这种重离子源直接结合了激光离子源和射频四极(RFQ)直线加速器。我们在该源上进行了碳离子加速试验，验证了这一原理。在214keV/u处观测到8 mA的总碳束电流。利用RFQ直线加速器下游的弯曲磁铁进行的束流分析表明，加速后的束流分别含有4.0和0.8 mA的C4+和C3+。
A heavy ion source based on a new principle of direct plasma injection system was developed at Tokyo Institute of Technology. This heavy ion source combines directly a laser ion source and a radio frequency quadrupole (RFQ) LINAC. We carried out an acceleration test of carbon ions on this source and proved this principle. An observed total carbon beam current of 8 mA at 214 keV/u was observed. Beam analysis using a bending magnet downstream of the RFQ LINAC showed that accelerated beam includes 4.0 and 0.8 mA C4+ and C3+, respectively.
