A Look Inside mRICH: Exploring Timing and Performance of a RICH Prototype^* — •Abhishek Anil Deshmukh for the CBM collaboration — Bergische Universität Wuppertal, Wuppertal, Deutschland

The CBM (Compressed Baryonic Matter) experiment to be built at the future FAIR facilities in Darmstadt, Germany aims to investigate the QCD phase diagram at high-net baryon densities and moderate temperatures. The FAIR accelerator will provide high-intensity heavy-ion beams for this fixed target experiment. To ensure the best operability of CBM at day one, a prototype of CBM is set up already now, including scaled-down versions of almost all the detectors later to be employed in the final CBM setup. One main goal of this prototype, called mini-CBM (mCBM), is to establish the free-streaming readout scheme envisioned for CBM. To test this scheme a dedicated test beam time was carried out at the beginning of 2024.

This contribution will focus on the mRICH detector, being part of mCBM. The mRICH is a proximity-focusing RICH detector that utilizes the same readout electronics as the RICH detector planned for the final CBM experiment. Particular emphasis is placed on the RICH ring matching with tracks from other detector systems. The discussion also covers the detector’s overall performance, which primarily depends on the aerogel radiator that has been in operation for over four years.
