    The 1.5 SDH-1 Pelletron Accelerator runs on a 40-sample MC-SNICS ion source modified with a spherical ionizer operating at high cathode voltage (7 kV). Injector modifications include the addition of a second einzel lens, an increased ion source voltage from 47.5 to 50.5 kV combined with a redesigned large gap injector magnet. These alterations allow for analytical error in the 2–3‰ range for near-modern samples under currents of up to 225 μA of 12C–. Sample sizes of 0.7mg C are routine, with somewhat lower precision on samples smaller than 0.3mg C. Any carbon-bearing material may be analyzed using the AMS.
