Qualification of a pixel sensor prototype produced by TSI — •Christoph Blattgerste for the Mu3e collaboration — Physikalisches Institut, Universität Heidelberg

High Voltage Monolithic Active Pixel Sensors (HV-MAPS) are suitable for particle physics experiments because they allow for high rate capability at low material budget and costs. HV-MAPS are fully integrated, can therefore be thinned to 50 µ m and thus multiple Coulomb scattering is reduced. The strong electric field in the depletion zone allows for fast charge collection via drift and a good time resolution.

The MuPix7, the first fully integrated HV-MAPS prototype, has been produced in the commercial 180 nm HV-CMOS process by the foundries AMS and TSI.

The relevant parameters of the two sensors are compared.
