The HVE low-energy multi-element AMS system with charge state selector in its high voltage terminal

High Voltage Engineering Europa B.V. (HVE) has designed a 300 kV AMS system for the measurement of ¹⁴C and of non-radiocarbon isotope species like ³H, ¹⁰Be, ²⁶Al, ⁴¹Ca, ¹²⁹I and actinides. The system features an electrostatic analyzer (ESA) as well as a high resolution analyzing magnet in the low-energy spectrometer, a 300 kV, vacuum insulated tandem accelerator and a high energy (HE) spectrometer comprising two high resolution magnets and an ESA in between. The layout of the system is shown. Located after the terminal stripper is an electrostatic deflector acting as charge state selector (CSS). The CSS fundamentally reduces a specific class of measurement background, especially beneficial for actinides.
