Abstract

The muon spin rotation/relaxation/resonance (\(\varvec{\mu }\)SR) spectroscopy is widely used as a unique tool for probing magnetic properties in materials. We aim to enhance this method by incorporating imaging functionality. In this study, we conducted an experiment using a new imaging device that utilizes positron tracking from muon decays to assess the reliability of positron tracking and its positional resolution. As a result, we have demonstrated that an image depicting a hole with a diameter of 5 mm could be reconstructed.
