Measurements of Positron Penetration Depth at Low Energies with a Pulsed Beam

• Positron lifetime measurements are made with the Chalmers Pulsed Positron Beam with the aim to investigatethe positron penetration depth according to positron energy. The experiments are executed for samples of verythin Au with a thickness of maximum 50 nm. Positron motion inside the material is simulated by PENELOPE-2008and comparisons to Makhov modeling are made. Positron methods are generally used to investigate properties ofdisturbed lattice structures but the following study concentrates mostly on making it possible to create positrondepth profiles in accordance to positron energy
