Two sub-MV accelerator mass spectrometers based on vacuum-insulated accelerators were designed, built, and tested by High Voltage Engineering Europa B.V. The first one is dedicated to ¹⁴C measurements. Both low- and high-energy mass analysis is done with permanent magnets. Unique to the ¹⁴C AMS system is that the accelerator terminal is equipped with a charge state selector suppressing ions of unwanted charge states, thereby reducing the system background for the ¹⁴C/¹²C ratio to the low 10⁻¹⁵ level. The ¹⁴C/¹²C precision is measured to be 0.16%. The second AMS system is a multi-element for ¹⁰Be, ¹⁴C, ²⁶Al, and ¹²⁹I measurements. The analysis of actinides is supported as well. It is equipped with two analyzing magnets in the high-energy spectrometer. The measured machine background for carbon is 7 × 10⁻¹⁶, for beryllium 5 × 10⁻¹⁵, for aluminum < 5 × 10⁻¹⁵ and for iodine 4 × 10⁻¹⁴.

由欧洲高压工程公司Europa BV设计，制造和测试了两台基于真空绝缘加速器的亚中压加速器质谱仪。第一个专用于¹⁴ C测量。低能量和高能量质量分析都是使用永磁体完成的。¹⁴ C AMS系统的独特之处在于，加速器终端配备了电荷状态选择器，可抑制有害电荷状态的离子，从而将¹⁴ C / ¹² C比的系统背景降低到10 ^-15低水平。测量的¹⁴ C / ¹² C精度为0.16％。第二个AMS系统是¹⁰ Be，¹⁴ C，²⁶ Al和¹²⁹ I测量值。还支持act系元素的分析。它在高能谱仪中配备了两个分析磁体。测得的碳的机器本底为7×10 ^-16，铍为5×10 ^-15，铝为<5×10 ^-15，碘为4×10 ^-14。
