ConclusionsThe 9 MV Tandem accelerator in Bucharest delivers a large variety of stable beams. The facility was completely modernized during the last years. A large variety of detecting devices are available:The RoSphere array with up to 25 HPGe detectors and/or LaBr3 detectors,Clover detectors,A plunger device,Neutron detectors.We are particularly well equipped for nuclear lifetime measurements.Financial support is available for certain type of measurements.Two PAC meetings /year; usually the requested beam time represents 150%-200% of the available beam time.
