First Observations from Mimosis-1 Single Event Upset Beam Tests.* — •Benedict Arnoldi-Meadows for the CBM-MVD collaboration — Goethe-Universität Frankfurt am Main

Mimosis-1 is the first full-sized prototype for the final cmos Monolithic Active Pixel Sensor to be used in the cbm Micro Vertex Detector (mvd). In the mvd, the sensors will be placed in close proximity to the beam and thus be exposed to ∼ 1 kHz/cm² heavy ions from the beam halo. Moreover, in the event of a failing dipole, the beam will be displaced and may hit sensors.

Two beam tests with mimosis-1 were conducted to determine single event effects induced by ∼ 1 A GeV heavy ions. First and preliminary results from the ongoing analysis of the tests will be presented.
