Description
The FoCal detector at the ALICE experiment at the CERN LHC is designed for studying a wide range of physics observables to probe non-linear QCD dynamics in an unexplored kinematic region. FoCal is a high-granularity calorimeter covering the pseudorapidity interval 3.4 < η < 5.8, and is scheduled to start operations in Run 4. The FoCal detector design has been optimized for studying prompt photons. The separation between isolated photons and pi0 relies on the high-granularity electromagnetic detector (FoCal-E) consisting of layers of Si-pads and Si-pixels interleaved with tungsten absorbers. A hadronic calorimeter (FoCal-H) completes the detector, providing photon isolation and jet measurements. In this talk, we will present the most recent results from R&D studies and test beams conducted at CERN in summer and fall 2022.
