sPHENIX HCal discussion

[Anthony M Hodges <ahodges21 AT student.gsu.edu>]

All,

I am planning on submitting the following abstract for the Southeastern Section of the APS meeting in November. It's quite short notice, but any comments/suggestions would be greatly appreciated, as the submission period closes this afternoon at 5PM.

Title: Probing Nuclear Interactions and the Quark Gluon Plasma with sPHENIX

 

Abstract:

A hot, dense state of matter, known as the Quark Gluon Plasma (QGP), is believed to have existed at the infancy of the universe, and it is also created in heavy ion collisions at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. To analyze the QGP, a new particle detector, sPHENIX, is currently planned to begin taking data in 2022. The nuclear physics group at Georgia State University is involved in the development and construction of the Hadronic Calorimeter, designed to measure the energy of hadronic matter produced in the collisions. The sPHENIX hadronic calorimeter itself is composed of individual scintillator tiles embedded with wavelength shifting fibers readout to silicon photomultipliers (SiPM’s). Results from the 2016 prototype test beam of the hadronic calorimeter subsystem demonstrate the hadron energy resolution satisfies the performance requirement for sPHENIX. Additionally, we are working to characterize the performance of the hadronic calorimeter tiles by exposing them to cosmic rays under different conditions. These cosmic ray tests include trigger configuration studies and discriminator threshold characterization using a CAEN DT7502 FEB. Results from these tests will allow us to establish a baseline calibration procedure for data taking with sPHENIX. "

Thank you,
