Calibrations of the sPHENIX Calorimeter System for Jet Reconstruction

sPHENIX, which is scheduled to begin collecting data at the Relativistic Heavy Ion Collider in February 2023, is composed of tracking detectors and calorimeters. The calorimeters are designed to precisely measure the energy of jets which are sprays of particles resulting from an energetic quark or gluon produced early in the collision. Detailed studies of the modification to these jets in heavy ion collisions are excellent probes of the quark gluon plasma produced in such collisions. The sPHENIX calorimeters include an electromagnetic calorimeter, an inner and outer hadronic calorimeter located inside and outside the solenoid magnet respectively. In preparation for data collection, initial calibrations have been determined and strategies for the calibrating the individual systems have been developed. This talk will focus on the later stages of the calibration process that ensures the combined jet energy is properly calibrated. In addition, this talk will report on hardware work related to these calibrations.
