The HVEE C-14 system at Groningen

Since May 1994, a new-generation accelerator mass spectrometer (AMS) has been fully operational at the Centre for Isotope Research in Groningen, The Netherlands, The fully automated and high-throughput accelerator mass spectrometry (AMS) system, manufactured by High Voltage Engineering Europa (HVEE) is dedicated to radiocarbon analysis. The HVEE 4130 C-14 AMS is able to analyze up to 3000 samples per year. The system is characterized by simultaneous transport of all three isotopes (C-12, C-13, C-14) and C-14 analysis with a precision below 0.5 pMC and a daily stability below 0.5 pMC. We present here a system description together with stability and performance measurements.
