The main facility of the new LABEC (LAboratorio di tecniche nucleari per i BEni Culturali) in Florence is a 3MV Tandetron accelerator, manufactured by High Voltage Engineering Europe, both used for Accelerator Mass Spectrometry and Ion Beam Analysis measurements. The AMS beam line is equipped with a 59-samples sputter ion source and a sequential injector on the low energy side, and a spectrometer composed by a 115° analysing magnet and a 65° electrostatic analyser on the high energy side. For radiocarbon measurements, a sample preparation laboratory has also been installed. Combustion of pre-treated organic samples is performed using an elemental analyser; collected CO2 is reduced to elemental graphite in one of the four graphitisation reactors installed. The performance of the whole system is presented: chemistry 14C blank values are in the order of 50000 years BP; measurements of radiocarbon concentration in standard reference materials demonstrate the good accuracy of the analysis.
