A Very Large HV-MAPS Tracking Telescope — •David Maximilian Immig for the Mu3e collaboration — Physikalisches Institut Universität Heidelberg

The MuPix-telescope is an evolving tracking telescope with very high rate capabilities that makes use of the most recent high-voltage monolithic active pixel sensor (HV-MAPS).
In the nominal setup, a DUT is sandwiched between three tracking layers of 100 µm thin HV-MAPS chips, at present MuPix10, complemented by scintillating tiles for additional time information. MuPix10 is a completely monolithic sensor with an active area of about 20 mm×20 mm, manufactured in the 180 nm HV-CMOS process at TSI Semiconductors with a pixel size of 80 µm×80 µm. Its trigger-less readout uses a column-drain architecture with on-chip zero suppression. 8b/10b encoded hit data is sent off the chip by three serial links with up to 1.6 Gbit/s each.
In the context of pixel sensor R&D this telescope is used to investigate efficiency, time resolution, and noise behaviour of different MuPix-like sensors. In this talk, the telescope concept is introduced. Highlights of several test beam campaigns at DESY and PSI will be presented which have been performed using a MuPix10-telescope.
