During a four week period in November and December ATLAS successfully took proton-lead collisions at 5 and 8 TeV collision energies. Extraordinary work was done by postdoc Martin Rybar who is the ATLAS Heavy Ion Trigger Co-coordinator and oversaw the allocations and monitoring of the 1500 triggers available for use in heavy ion collisions throughout the run. Graduate students Akshat Puri and Virginia Bailey were present during the run to validate the data and its reconstruction. This data will be analyzed for years to come. The next ATLAS heavy ion running will be in 2018 with lead-lead collisions.
