Description
High energy heavy ion collisions at RHIC create strongly coupled, hot, dense matter (quark-gluon plasma), which performs like a perfect fluid. Fundamental questions such as how and why the quark-gluon plasma behaves as a perfect fluid in the vicinity of the critical temperature, can only be fully addressed with world-class
jet observables at RHIC energies. Jet probes in medium are crucial to understand the coupling of the quark gluon plasma, the origin of this coupling, and the mechanism of rapid equilibration. During past three years, the PHENIX collaboration has developed a detector development plan for the next decade, referred as sPHENIX, which will incorporate electromagnetic (EMCAL) and hadronic (HCAL) calorimeters with a large pseudo-rapidity range, and full azimuthal coverage. The HCAL will be first large coverage hadronic calorimeter ever to be used at RHIC, and will enable a systematic study of jets in quark-gluon plasma. A novelty accordion inspired HCAL prototype based on scintillator plates and steel absorber plates has been constructed and tested using test beam at Fermilab. It has two longitudinal sections, and a total depth of 5 interaction length. In this poster, we will present the test beam performance, and single particle GEANT 4 simulation studies for the HCAL prototype.
