Figure 5. . Compact, low-maintenance accelerator mass spectrometry systems.

(A) The single stage open stack accelerator mass spectrometry (AMS) system unit from National Electrostatics Corporation is an air-insulated single stage accelerator that is simple in design. The instrument is robust and easy to maintain as it does not have any moving parts or pressurized insulating tank around the high-voltage section. The combination of simple design, excellent performance and reasonable price has resulted in 12 new National Electrostatics Corporation AMS installations as of 2013. (B) With dimensions of only 3.4 m × 2.6 m × 2 m, the pictured green MICADAS analyzing dating AMS system is the most compact commercially available ¹⁴C-AMS system. Fixed magnets are used in place of electromagnets, reducing the overall footprint and power consumption. In conjunction with the gas interface system, this AMS system performs fully automated gas measurements with an autosampler, an elemental analyzer or CO₂ filled glass or quartz tubes (provided by ETH).
