This new AMS system around the patented helium stripping technology with an accelerator voltage of just 50 kV – LEA was developed by Ionplus . LEA’s lower accelerator voltage led to a significant reduction in footprint without compromising its performance. With its dimensions of just 2.6 m x 1.8 m and a height of 1.5 m, LEA is less than half the size of MICADAS. And by that the new, most compact ¹⁴C-AMS system in the world. By using much of the same concepts and components found in MICADAS, the new LEA system also offers the same features like: a hybrid Cs sputter ion source for measuring gas and solid samples, random access samples changer with air lock, allowing continuous measurement and the maintenance-free, vacuum insulated tandem accelerator. The helium stripping at low voltages offers an even higher transmission of over 50 % and unparalleled measurement stability.
