The Relativistic Nuclear Physics Group (RNP) has a strong track record in developing large scale instrumentation for particle and nuclear physics experiments. The group is currently collaborating on the ALICE Experiment at the CERN LHC, where it has recently completed the construction of the readout system upgrade of the Time Projection Chamber and contributed to the construction of the ALICE Inner Tracking System based on monolithic active pixel sensors. In collaboration with the sPHENIX experiment at RHIC, a similar tracker is being developed for which ORNL is developing the streaming read-out electronics. Additionally, the RNP group is currently involved in the conceptual design of one of the experiments, ECCE, for the future Electron Ion Collider situated at Brookhaven National Laboratory. In synergy with the foreseen upgrades at the LHC, the main focus of our R&D efforts are novel calorimetry and silicon-tracking and PID detectors.
Research in Relativistic Nuclear Physics Group maps the quark - gluon structure and dynamics of strongly interacting matter including the proton and nuclei at the future Electron Ion Collider and the quark gluon plasma through heavy ion experiments at the Large Hadron Collider.
