CBM-TRD QA algorithm results for mCBM 2021 — •Axel Puntke — Institut für Kernphysik, Münster, Germany

The Compressed Baryonic Matter (CBM) experiment at the future Facility for Antiproton and Ion Research (FAIR) will explore the QCD phase diagram in the region of very high net baryon densities. The Transition Radiation Detector (TRD) is an important subdetector of the final CBM experiment and is used to identify electrons at high momenta, contributes to tracking of particles and supports the identification of light nuclei via their energy loss.

For commissioning and performance measurements, the TRD takes part in the mCBM high-rate beam campaigns at the SIS18 accelerator, which are part of the FAIR-Phase 0 program. For this purpose, a set of QA algorithms is developed which can automatically produce QA plots, based on the used configuration parameters of the current setup. This also includes correlations with other subsystems (e.g. TOF) which have recorded data simultaneously.

In this poster, the first results, based on the data recorded during the mCBM 2021 beamtime, will be shown . Besides TRD there were also the subsystems TOF, STS, RICH and PSD involved and can be used for temporal and spatial correlations.
