Abstract

At the Large Hadron Collider collisions of heavy ions achieve an extremely high energy density such that a thermalized medium of quarks and gluons a Quark Gluon Plasma QGP is produced Over the last several years the heavy ion program at the ATLAS experiment has achieved great success studying heavy ion collisions and characterizing the QGP In addition to the study of the QGP in heavy ion collisions there has been a surprising observation of QGP like signatures even in smaller collisions systems pp and pA which were not previously expected to produce a QGP This result has forced the reconsideration of longstanding assumptions in the field and its full consequences are still under active exploration The program described above has focused primarily on hadronic collisions observed at mid rapidity with forward rapidity measurements playing only a supporting role Recently interest has grown in collisions in which the accelerated ion beams are considered as a beam of quasi real photons due to the EM fields of the ion beams For robust identification of such collisions both photon photon and photo nuclear as well as diffractive nuclear collisions require detector acceptance at forward rapidity and this in turn requires upgrading the detector capabilities The measurements of interest as well as plans for upgrading the detector in particular a radiation hard photon and neutron detector for forward rapidity will be presented These new facets of the heavy ion program at the LHC will be discussed
