At the end of September HIE-ISOLDE celebrated the first physics experiment successfully started running using radioactive beams from the newly upgraded HIE-ISOLDE facility. The experiment was ready to go after the second of two cryomodules (containing the accelerating cavities) were installed – marking the end of the installation of phase one of HIE-ISOLDE. This new linear accelerator enables ISOLDE to reach higher energy. A celebration, hosted by Belgian State Secretary Ms Elke Sleurs, was held on 28 September 2016 to mark the occasion.
