Some Recent Advances in Experiments with Radioactive Beams

In the last ten years, impressive scientific results were obtained at radioactive nuclear beams (RNB) facilities around the world. The existing RNB facilities are in a process of continuous upgrades and improvement. In parallel, the facilities of a future generation are actively discussed and numerous R&D studies are performed.  I will discuss some new developments such as 1) application of implanted helium targets for RNB experiments, 2) in-source spectroscopy with a laser ionizing source, 3) in-trap conversion electron spectroscopy, and 4) conversion of relativistic products of fragmentation to high-quality low-energy beam. These experiments and R&D programs were performed at several RNB facilities in Europe and the US (Louvain-la-Neuve , ISOLDE, and NSCL).  In this discussion, I will try to give a flavor of a broad range of activities and a rich variety of physical phenomena that one encounters working at RNB laboratories.
