The High Acceptance Di-Electron Spectrometer (HADES) experiment has designed and used a Low Gain Avalanche Detector (LGAD) based in-beam detector for its high rate 4.5 GeV pp production beam time in February 2022. As LGADs offer high-precision timing measurements with high spatial granularity and high radiation hardness, they were the sensors of choice for the in-beam detector.
The detector consisted of two FBK LGADs with a form factor of 2 x 2 cm² and 96 half-strips each. It was used for beam monitoring purposes during the beam time and will assist in particle identification by providing a precise reaction time (T0).
This contribution will present the calibration procedure of the detector as well as its performance with respect to the reached timing precision.
