sPHENIX: Experiment overview

sPHENIX is a newly built state-of-the-art detector at RHIC designed for precision studies of the Quark Gluon Plasma and Cold QCD. It has exceptional reconstruction performance for high-pT jets, photons and heavy flavor probes with a broad kinematic reach and high rate capability to take large statistics datasets of A+A, p+p and p+A collisions. sPHENIX construction was completed in April 2023. It was commissioned and took first data in the RHIC 2023 Au+Au Run. This paper presents details of the detector design and first physics data from the 2024 p+p and Au+Au runs.
