On the path to module integration with the HV-MAPS
prototype MuPix9 — •Heiko Augustin1, Alena Larissa Weber1,2, and Ivan Perić2 for the Mu3e collaboration — 1Physikalisches Institut Heidelberg — 2Karlsruher Institut für Technologie
The Mu3e experiment is dedicated to the search for the charged lepton flavour violating decay µ+ → e+e−e+ with an unprecedented sensitivity of one in 1016 decays. In the Standard Model this decay is suppressed to a branching ratio below 10−54. Thus, any observation of a signal is a clear sign for New Physics. To reach the sensitivity goal a pixel tracker with low material budget and high rate capability is required. The technology of choice are High Voltage Monolithic Active Pixel Sensors (HV-MAPS) produced in the AMS aH18 180 nm HV-CMOS process, which allows to build fast pixel detectors thinned to 50 µm .
In this talk the architecture and test structures of the MuPix9 prototype are presented. It houses a shunt regulator and a fully monolithic pixel sensor engineered for the use within a serial powering chain. Further it contains a synthesized slow control statemachine aiming to reduce the slow control complexity in the view of module integration.
First results on the MuPix9 performance are presented and the road map for the module integration is depicted.
