Description

ALICE3, the next-generation heavy-ion experiment, has been proposed for the LHC RUN 5 and 6 to investigate the Quark Gluon Plasma properties, exploiting precise measurements of heavy-flavour probes as well as electromagnetic radiation. These measurements require excellent particle identification (PID) capabilities in a wide transverse momentum range.
The development of a Ring Imaging Cherenkov detector using aerogel radiator and SiPM-based photo-detector is proposed for the charged PID in the ALICE 3 experiment.
A high PID performance is expected thanks to large photon detection efficiency and granularity of the sensor, even in high multiplicity Pb-Pb collisions.
The particle separation capability of e/$\pi$, and $\pi$/K/p can be achieved up to about 2 GeV/c and 10 GeV/c, respectively.
The detector specifications and performance, obtained by means of dedicated Monte Carlo simulation, will be presented. The design and R&D challenges will be also discussed.
