A Silicon Pixel Tracker for µSR Experiments — •Lukas Mandok for the HD-HVMAPS collaboration — Physikalisches Institut Universität Heidelberg

Muon spin rotation (µSR) is a long existing baseline technique in condensed matter research, facilitating the exploration of magnetic and superconducting phenomena. Traditional reliance on scintillator-based detectors, limited in rate and spatial resolution, hinders the investigation of novel quantum materials. The use of ultra-thin silicon pixel sensors for precise track reconstruction has the potential to revolutionize µSR spectrometry.
Recent advancements in this direction include the construction of a silicon based µSR spectrometer. It is comprised of four quad module layers made from MuPix11 sensors. Studies conducted at a polarized muon beamline at PSI, focusing on µSR samples, highlight the technology’s promising capabilities. Preliminary results showcase muon spin precession measurements comparable to traditional techniques, while eliminating accidental background and enabling resolution of details on a 1 mm scale on the sample.

This technology shows great potential for efficient, high-rate investigations of multiple samples simultaneously, enhancing lateral resolution and even extending observation times.
