摘　　要：描述了重离子加速器放射性次级束流线束流诊断技术的新发展 ,它包括初级束流在线监测研制的非拦截式法拉第筒 ,监测低强度初级束流的塑料闪烁探测器 ,测量放射性次级束流剖面的大面积双维位置灵敏平行板雪崩室等 .这些新研制的束流诊断装置的运用 ,明显提高了设置、调整、确定重离子加速器放射性次级束流线运行参数的速度和准确性 ,改善了放射性次级束流纯度和质量 ,并使得重离子加速器放射性次级束流线的运行更简洁、迅速和有效 .The development of beam diagnosis at RIBLL has been carried out. There are three kinds of diagnosis devices, i.e. the transmittal Faraday cup, plastic scintillator and two dimensional position sensitive PPAC. The Faraday cup is usually used to measure primary beam in the experiments. The scintillator readout with photomultipliers is set to monitor the primary beam in low intensity during tuning RIBLL. The PPACs (C 1,T 1,C 2,T 2) with 100mm×100mm of sensitive area are installed to measure the RIB profiles. So the performances of RIBLL are improved.
