Description
The ALICE Collaboration completed the upgrade of the detector for the LHC Run 3 and is now commissioning for upcoming first collisions in LHC pilot runs for data taking. In parallel, R&D activities and simulation studies are being performed to define the future of the experiment beyond LHC Run 3.
Two detector upgrades are foreseen for the next long shutdown (LS3). The first is the replacement of the three beam-pipe closer layers of the Inner Tracking System with a novel vertex detector consisting of curved wafer-scale ultra-thin silicon sensors arranged in perfectly cylindrical layers to improve impact parameter resolution and significantly extend the physics capability for the study of heavy-flavour production and low-mass dielectrons. The second upgrade for the LS3 is the addition of a novel concept Forward Calorimeter (FoCal) detector at large rapidity consisting of a Si-W electromagnetic calorimeter with pad and pixel readout, that will equip the experiment with unique capabilities to measure small-x gluon distributions via prompt photon production.
A proposal of a next-generation heavy-ion experiment for LHC Run 5 is also in preparation and will be discussed. The aim is to perform novel measurements of electromagnetic and hadronic probes of the QGP, such as the production of multiply-charmed baryons, which have so far been inaccessible, both because of detector performance and luminosity. The concept of the new apparatus foresees an extensive usage of thin silicon sensors for tracking and a modern particle identification system, combining a silicon-based time of flight detector, a RICH and preshower detector.
