DirectAMS debuted as an affordable, high-throughput radiocarbon dating service at AMS-12 in 2011. A dedicated pretreatment laboratory has been in operation since 2012 in conjunction with an NEC 1.5SDH-1 Compact Pelletron Accelerator Mass Spectrometer installed in 2006. Over 60,000 14C radiocarbon dating targets have been measured over the last decade. The status of the laboratory and performance from routinely measured standards, reference, and blank materials are presented.
