Accelerator Mass Spectrometer

Description: The Radiocarbon Laboratory is equipped with a National Electronics Corporation compact spectrometer with a 0.5MV accelerator (NEC 1.5SDH-1) installed in April 2016.  The primary modifications impacting analytical measurement error are the use of a spherical ionizer ion source operating at high cathode voltage (7V) to generate intense C- beams, plus injection beam line changes for better ion-optical matching to the accelerator.
