MicroMegas for measuring the direction of electromagnetic showers — •Stefan Kormannshaus — Johannes Gutenberg-Universitaet Mainz

The SHiP experiment, which is planned at the CERN SPS, aims to measure new, weakly interacting non-Standard Model particles. To reconstruct decays of neutral particles like axions into photons, not only the energy of the photons, but also their direction needs to be measured. The electromagnetic calorimeter is therefore planned to be equipped with layers of high-resolution MicroMegas detectors within the production, to measure the position of the electromagnetic showers inside the calorimeter. MicroMegas have general advantages for this purpose, like having a sufficiently precise spatial resolution (∼ 50 µ m) and a small longitudinal extent of only a few cm. In this talk we present simulation studies of different calorimeter designs with high-precision MicroMegas layers and of the achievable angular resolution of electromagnetic showers.
