Status of MRPC performance for the endcap-time-of-flight upgrade of STAR — •Philipp Weidenkaff for the CBM collaboration — Ruprecht-Karls-Universität Heidelberg

As part of the FAIR phase 0 program, CBM-ToF MRPC modules have been installed as endcap-time-of-flight detectors in STAR for the current beam-energy-scan II (BES II) program in 2019 and 2020. These detectors provide a major improvement to the particle identification capability of the experiment in the forward region (1.0 < η < 1.5), which is especially necessary for the fixed target program. An Analysis of the MRPC performace in terms of time resolution, efficiency and matching to STAR-TPC tracks will be presentent in this talk. The Results are based on the 2019 run as well as first data of the 2020 run.

The project is partially founded by BMBF 05P15VHFC1.
