A model for positron annihilation in multi-layer systems by solving the diffusion equation using different positron affinities Open
We present a method for solving the positron diffusion equation in multi-layer systems. Our approach incorporates material-specific implantation profiles, diffusion parameters, and positron affinities. It utilizes a Markov chain approach t…

Surface and near-surface positron annihilation spectroscopy at very low positron energy Open
We present a monoenergetic positron beam specifically tailored to the needs of (near-) surface positron annihilation spectroscopy. The Setup for LOw-energy Positron Experiments (SLOPE) comprises a high-activity 22 Na source, a tungsten mod…
