Test beam results of a Depleted Monolithic Active Pixel Sensor (DMAPS) prototype — •Theresa Obermann1, Tomasz Hemperek1, Fabian Hügging1, Hans Krüger1, Benjamin Schwenker2, and Norbert Wermes1 for the ATLAS Pixel collaboration — 1Nussallee 11, 53113 Bonn — 2Friedrich-Hund-Platz 1, 37077 Göttingen
New monolithic detector concepts are currently being explored for future particle physics experiments, in particular for the upgrade of the ATLAS detector. Common to monolithic pixel detectors is the integration of the front-end circuitry and the sensor on the same silicon substrate. The DMAPS concept makes use of high resistive silicon as substrate. It enables the application of a high bias voltage to create a drift field for the charge collection in the sensor part as well as the full usage of CMOS logic in the same piece of silicon. DMAPS prototypes from several foundries are available since three years and have been extensively characterized in the lab. In this talk, results of test beam campaigns, with neutron irradiated prototypes implemented in the ESPROS process, will be presented.
