WebThe major ion beam facilities at the Tandem laboratory at Uppsala University comprise of a 5 MV tandem accelerator, a 200 kV MICADAS compact radiocarbon dating system, ion implantation facilities with three beam lines as well as a system for low-energy ion scattering. Requirements PhD degree in physics, engineering or equivalent. WebBecause the electron beam scatters more at greater depths, this results in poorer resolution than can be obtained with the SE detector, which is typically also used with much lower beam currents. To improve BSE image resolution, reduce the beam voltage (even to below 1000 V) and increase probe current or detector gain as necessary.
