Abstract

ATLAS is one of four large detectors at the Large Hadron Collider (LHC) at CERN. The Zero Degree Calorimeter (ZDC) is a hadronic calorimeter intended to detect the energy of neutrons that enter it. In heavy-ion collisions spectator neutrons, those which do not participate in the A+A collision, continue along the LHC tunnel to the ZDCs on either side of the collision point. The presence of these neutrons indicates the breakup of the heavy-ion, typically due to an inelastic collision, which can be triggered on using the ZDC. Further, the presence or absence of a signal in one or both ZDC in conjunction with mid-rapidity measurements can be used to select photon-photon and photo-nuclear interactions. The number of spectator neutrons from a given collision helps characterize the nature of A + A , p + A, γ + A and γ + γ collision.

The increase in luminosity at the LHC create challenges we need to account for in any future ZDC design. We present the challenges the ZDC detector is facing in future runs of the LHC and elaborate some of the more interesting R&D and on going endeavors, especially the participation of BGU team
