Schloss Ringberg, Tegernsee, Germany, 11–14 March 2018
The Atacama Pathfinder Experiment (APEX) 12-metre submillimetre telescope has been in operation for more than 12 years and has contributed to a wide variety of submillimetre astronomy science areas, from the discoveries of new molecules to deep imaging of the submillimetre sky. The telescope is currently undergoing a major upgrade to ensure reliable operations until at least 2022. In addition, a new suite of instruments is being commissioned, including new large cameras for wide-field continuum imaging and new heterodyne instruments highly complementary to ALMA. The conference venue at Ringberg Castle provides a unique setting for in depth discussions on new scientific results with APEX, synergies with other observatories, and the exploitation of the upcoming new APEX capabilities.
