Description

Maps of the sPHENIX EMCal in absorber-block density, light-transmission yield, relative scintillation response, and cosmic MPV are presented. All maps were collected before the arrival of RHIC beams for sPHENIX and will serve as starting point for an advanced calibration of the EMCal with neutral pions produced in collisions of gold nuclei (Au-Au) or protons (p-p). Section 1 of this note summarizes the sPHENIX EMCal properties and construction. Section 2 summarizes the block and channel properties and how they were obtained. Sector maps are presented in section 3 and the documentation of the code to generate the maps is given in section 4. Lastly, the appendix lists some production details that may be useful for the management of a future calorimeter project.
