Analysis of CBM - TOF module response with cosmic rays — •Dennis Sauter for the CBM collaboration — Physikalisches Institut, Universität Heidelberg, Deutschland

The future Compressed Baryonic Matter (CBM) experiment is planned to utilize MRPC detectors for its 120 m2 large ToF wall. To reconstruct the majority of the produced particles at an interaction rate of up to 10 MHz, it is of utmost importance that detection efficiency reaches upper values close to 100of 50-60 ps. The MRPC prototypes 3a & 3b are planned to be used in the intermediate and low rate region of the wall with expected fluxes of a few kHz/cm2. Utilizing cosmic muon radiation, these prototypes were extensively tested before exposing them to their designed rate, which will happen in the mCBM experiment in 2019 at GSI. With a test setup of 6 stacked MRPCs and through analysis with the CBM Tracker class it was possible to verify the required level of performance on both types. In addition, signals of particles that seemed to come from below the setup were found. This property of the tracker allowed for distinguishing between muons and their decay products, electrons.
