Ireland used to participate in bubble-chamber experiments, and subsequently focused on cosmic-ray physics. However, University College Dublin (UCD) has made two senior appointments in experimental high-energy physics, Trinity College Dublin has made a senior appointment in theoretical physics, and the Dublin Institute for Advanced Studies has appointed a former CERN TH staff member to a senior position.
UCD has been accepted into both CMS and LHCb, and Ireland has a strong interest in Grid technology, reflected in its memberships of CrossGrid and now EGEE.
