ALICE 3 - The next-generation heavy-ion experiment at the LHC — •Lars Döpper for the ALICE Germany collaboration — Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn — Forschungs- und Technologiezentrum Detektorphysik, Universität Bonn

ALICE 3 is a completely new heavy-ion setup at the LHC, proposed as the successor and next generation of the current ALICE detector. To utilize the LHC to its full potential as a heavy-ion collider during Run 5, a completely new detector is required and envisioned to start operation after the Long Shutdown 4 in 2036.

Building on the physics achievements of Runs 3 and 4, ALICE 3 is designed to address key open questions in heavy-ion physics, with a particular focus on the heavy-flavour sector at low transverse momentum. These measurements will provide unique sensitivity to the time evolution of the quark-gluon plasma and its approach to thermal equilibrium. To facilitate these precision measurements, ALICE 3 will consist of a full silicon-pixel tracking system, covering the pseudorapidity range of at least |η| < 2.5. This tracking system at the heart of ALICE 3 is further complemented by systems for particle identification. All of this will be encased within a new superconducting solenoid magnet with a field strength of 2 T.

In this talk I will give an overview about the motivation behind this new detector, the different detector subsystems and some of the challenges we have yet to overcome on our journey towards ALICE 3.
