The BEAST II Experiment at Belle II: Characterization of the commissioning detector system for SuperKEKB — Patrick Ahlburg, Andreas Eyring, Viacheslav Filimonov, Hans Krueger, •Laura Mari, Carlos Marinas, David-Leon Pohl, Norbert Wermes, and Jochen Dingfelder — University of Bonn

Before the upgraded vertex detector for the Belle II experiment at the SuperKEKB collider in Japan will be installed, a dedicated detector system for machine commissioning (BEAST II) will be employed. One of its main objectives is to measure and characterize the different background types in order to ensure a safe environment before the installation of the actual silicon detector systems close to the interaction point.

FANGS, a detector system at BEAST II, based on ATLAS-IBL front-end electronics and planar silicon sensors is currently being developed for this purpose. The unique feature of this detector system is the high energy resolution achieved by using an external FPGA clock to sample the time-over-threshold signal, while keeping the excellent timing properties. The complete detector system will be presented in this talk.
