  2. 1. Beyond scattering – what more can be learned from pulsed keV ion beams?

    Author : Svenja Lohmann; Daniel Primetzhofer; Andreas Wucher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Charge exchange; Deep UV photons; Electron emission; Silicon; Sputtering; TOF-MEIS; Fysik; Physics;

    Abstract : Interactions of energetic ions with matter govern processes as diverse as the influence of solar wind, hadron therapy for cancer treatment and plasma-wall interactions in fusion devices, and are used for controlled manipulation of materials properties as well as analytical methods. The scattering of ions from target nuclei and electrons does not only lead to energy deposition, but can induce the emission of different secondary particles including electrons, photons, sputtered target ions and neutrals as well as nuclear reaction products.

    Abstract : Medium energy ion scattering (MEIS) is an experimental technique for the high-resolution depth profiling of thin films. Commonly, ions with energies between several ten to a few hundred keV are employed as probes, and backscattered particles are detected. READ MORE
