sPHENIX is a new collider experiment at Relativistic Heavy Ion Collider (RHIC). It seeks to address fundamental questions on the nature of the Quark-Gluon Plasma (QGP) and proton-spin puzzle by precisely measuring the hard probes such as photons, jets and electron pairs. In addition, sPHENIX will collect abundant statistic measurements extending the kinematic region overlapping the LHC’s. It allows us to have a complete picture of QGP’s properties. These goals rely on large acceptance, high data-taking rate, full barrel calorimeters, 1.4 Tesla solenoid magnet and advanced tracking system of the sPHENIX detector. The sPHENIX project was proposed by the former PHENIX collaboration in 2012. After more than 10 years of preparation, sPHENIX moved to the commissioning phase with beams and cosmic rays in May 2023. This talk will give you an overview of the sPHENIX experiment including the detector introduction, the physics goals of sPHENIX and the exciting results sPHENIX achieved during the commissioning.
