The MuPix Telescope - Tracking Low Momentum Particles at High Rates — •Lennart Huth for the Mu3e collaboration — Physikalisches Institut Universität Heidelberg

New physics beyond the Standard Model as predicted by several models includes charged lepton flavor violation (cLFV). The search for cLFV decays requires high statistics to be sensitive to small branching ratios (BRs). The Mu3e experiment will search for the cLFV decay µ⁺ → e⁺ e⁻ e⁺ with a sensitivity in BR of 10⁻¹⁶. The required high rate and the low momentum of the decay particles are the biggest challenges. To reduce multiple Coulomb scattering, the dominant measurement uncertainty thin detectors are needed. For Mu3e, the novel concept of High Voltage Monolithic Active Pixel Sensors (HV-MAPS) is chosen.
To test the scalability, data acquisition, control and online monitoring of Mu3e and for sensor characterization at test beams, a particle tracking telescope has been developed. It is optimized to handle high rates of low momentum particle of over 1 MHz.
This talk introduces the concept and setup of the telescope. Efficiency, timing and noise results from test beam campaigns at PSI and DESY are also shown.
