The MuPix10 - the current state of design — •Alena Weber for the Mu3e collaboration — Physikalisches Institut Heidelberg — Karlsruher Institut für Technologie
The Mu3e experiment is searching for the charged lepton flavor violating decay µ+ → e+e−e+ with a sensitivity of one in 1016 decays (in phase II). High Voltage Monolithic Active Pixel Sensors (HV-MAPS) will be used in four tracking layers.
In the last years, several prototypes of different size have been designed and tested. In 2017, a first large prototype (MuPix8) with a size of 1 x 2 cm2 was submitted and successfully tested. Another small prototype, the MuPix9, has been developed to test several small circuits. The next important design step is MuPix10, which has a full recticle size (about 2 x 2 cm2 ). The design should fulfill all Mu3e requirements and be close to the final version to be installed in the experiment. Several design blocks undergo a redesign for a better energy and time resolution and for a more uniform voltage supply inside the chip. Furthermore, the design has to be ported to a new fabrication process (TSI 180 nm HVCMOS).
In this talk, the current state of the MuPix10 design will be presented.
