Description
The Mu3e experiment searches for the lepton flavor violating decay $μ^+→e^+e^−e^+$ with an ultimate aimed sensitivity of $1$ event in $10^{16}$ decays.
For this goal a very high momentum resolution is required.
This goal can only be achieved by reducing the material budget per tracking layer to $X/X_0\approx0.1\,\%$ and by using gaseous helium as coolant, a novelty for particle detectors.
The pixel detector is based on High-Voltage Monolithic Active Pixel Sensors (HV-MAPS) which are thinned down to a thickness of $50\,$μm.
This poster offers an overview of the Mu3e pixel detector, encompassing the vertex detector, the outer tracking layers, and the gaseous helium cooling system.
Additionally, it outlines the upcoming production of the pixel detector, including the quality control measures for the chips and modules.
