sPHENIXThe physics motivations for the sPHENIX detector are to study the quark gluon plasma (QGP) produced in the collisions of large nuclei using the modification of jets from their vacuum fragmentation configurations as the propagate through the QGP. Together with the ATLAS program, the detectors at RHIC (sPHENIX) and the LHC (ATLAS) will allow us to constrain the temperature dependence of the properties of the QGP. The highest temperature of the QGP reached in any collision depends on the energy of the collision and those moving to RHIC with a 25x lower collision energy provides the largest lever arm available to study these properties. This lower temperature is closer to the minimum QGP temperature than at the LHC and thus measurements at RHIC are potentially very sensitive to why the QGP behaves as it does.

We have a leading role in the electromagnetic calorimeter subsystem for sPHENIX and have produced half of the electromagnetic calorimeter modules that will be tested in an sPHENIX testbeam at Fermilab in April 2016.
