Abstract

The 1 MV multi-element AMS system at Beijing Normal University, built by High Voltage Engineering Europa B.V., is now commissioned after some delay. This advanced 1 MV system is uniquely configured to accommodate low background analyses of all elements from tritium to actinides, including an additional detector line dedicated to beryllium ion detection with improved overall ion transmission efficiency. For the main detector line, both the low- and high-energy magnet chambers are electrically insulated so that a rapid sequential isotope selection mode can be used for measuring actinide isotopes at ∼ 1 Hz cycling rate. In this report, data covering ¹⁰Be, ¹⁴C, ²⁶Al, ⁴¹Ca, ¹²⁹I, ^239,240Pu and ²³⁶U from the recently completed on-site acceptance tests are presented. The initial experiences with routine radiocarbon analyses are also reported.
