In addition to the CMS experiment at CERN, the MIT Heavy Ion Group also involves in the planned sPHENIX experiment at RHIC. Currently, Professor Gunther Roland is serving as the spokesperson for the sPHENIX experiment. Graduate student Zhaozhong Shi has been working on the sPHENIX electromagnetic calorimeter. The 2018 sPHENIX Test Beam (T-1044), which tests the prototypes of the EMCAL, HCAL, MVTX, and INTT subdetectors, has been successfully carried out at Fermilab Test Beam Facilities from Feb 21 to Mar 28. This Test Beam project served as an important part of the validation and testing process of the sPHENIX experiment
Zhaozhong Shi participated in the test beam at Fermilab. He took the EMCAL position scan data and analyzed its energy uniformity. His results will help sPHENIX physicists to understand the current performance of EMCAL so that one could optimize the EMCAL detector design for future photon and jet measurements with sPHENIX. We look forward to the construction and data taking of the sPHENIX expeeriment in the future!
