Contrast modes in a 3D ion transmission approach at keV energies
R. Holeňák, S. Lohmann, D. Primetzhofer
We present options for visualizing contrast maps in 3D ion transmission experiments. Simultaneous measurement of angular distributions and flight time of ions transmitted through s…

Assessing electron emission induced by pulsed ion beams: a time-of-flight approach
Svenja Lohmann, Anna Niggas, Vincent Charnay +2
We present a method to measure the kinetic energy of electrons emitted upon ion impact via their time-of-flight. Pulsed beams of H, D, He and Ne ions with…

Disparate energy scaling of trajectory-dependent electronic excitations for slow protons and He ions
Svenja Lohmann, Daniel Primetzhofer
We have simultaneously measured angular distributions and electronic energy loss of helium ions and protons directly transmitted through self-supporting, single-crystalline silicon…
