Dear all,

 I was asked by PSB to present recent results on sPHENIX project. Here is my draft abstract. Comments or suggestions are welcome. The submission deadline is June 30th.

Title: Readiness for physics data taking of sPHENIX experiment at RHIC

Abstract: 

　sPHENIX is a new versatile detector at the Relativistic Heavy Ion Collider (RHIC) in the Brookhaven National Laboratory, and in the middle of commissioning prior to physics data taking this Summer to Fall. The sPHENIX experiment will collect high statistics nucleus-nucleus, proton-nucleus and proton-proton data, enabling state-of-the-art studies of jet modification, upsilon suppression and open heavy flavor production to probe the microscopic nature of the strongly-coupled Quark Gluon Plasma complementaly to thoese measurements from the LHC experiments, and will allow a broad range of cold QCD studies. The sPHENIX detector will provide precision vertexing, tracking and electromagnetic and hadronic calorimetry in the central pseudorapidity region |η| < 1.1, with full azimuth coverage, at the full RHIC collision rate, delivering unprecedented data sets for hard probe tomography measurements at RHIC.
sPHENIX folllows the typical geometry of collider detectors, with a tracking system consisting of a MAPS microvertex detector (MVTX), a silicon strip intermediate tracker (INTT) and a time projection chamber (TPC). The calorimeter stack includes a tungsten/scintillating fiber electromagnetic calorimeter (EMCAL) and a steel/scintillator tile hadronic calorimeter (HCAL), divided into inner and outer parts. The inner HCAL sits inside a 1.5 T superconducting solenoid, which was obtained from the decommissioned BaBar detector. In this talk, I will introduce physics goal of the sPHENIX experiment and the latest status of the detector commissioning.

Best regards,
