Future upgrades of ALICE for Run 4
Original language description
The ALICE Collaboration is preparing two upgrades for installation during LHC Long Shutdown 3. The first project is the replacement of the inner barrel of the Inner Tracking System (ITS) detector with cylindrical layers based on large-scale, wafer-sized, bent, monolithic active pixel sensors. This technology will provide a detector with an unprecedentedly low material budget and will allow unparalleled vertexing performance. The second project will add the novel concept of a Forward Calorimeter (FoCal), consisting of a Si-W electromagnetic calorimeter, with pad and pixel readout, and a conventional metal-scintillator hadronic calorimeter. The design of the electromagnetic calorimeter aims for high spatial resolution for the separation of nearby photon showers. This article presents the R&D programs of both projects and discusses the prospects for physics.
