Target Chamber and Rotating Target Wheel for Synthesis of Superheavy Elements at Radioactive Ion Beam Line of Lanzhou

摘要: 文章介绍兰州重离子加速器放射性次级束流线（RIBLL）的超重元素合成实验靶室和转靶系统，并对改进的真空密封磁耦合传动机械作简单描述。转靶系统采用可程序控制的无级变速电机、真空密封磁流体耦合和特殊皮带传动机构，使得靶盘转速在0~600 r/min范围内可调，靶盘边缘摆幅＜0.2 mm。

Abstract: The target chamber and the rotating target wheel for synthesis of superheavy elements at Radioactive Ion Beam Line of Lanzhou(RIBLL) are described in the paper. The modified vacuum isolating magnetic coupling rotation device driven by step-motor is also shown. The rotating target wheel is composed of a programmable brushless motor, a vacuum sealing magnetic liquid feed-through and high torque-drive(HTD) strap. The rotation speed of the wheel can be turned from 0 to 600 r•min^-1. The vibration of the target wheel is <0.2 mm.
