Once the home of the HERA ep collider, Deutsches Elektronen-Synchrotron, DESY, is located to the west of the city, in Bahrenfeld. The lab hosts two of the largest ATLAS and CMS groups, a Belle 2 group, and many smaller on site Particle Physics experiments such as ALPS, There is also an increasingly large photon science presence on site: PETRA III/IV, XFEL, CFEL as well as plasma wakefield research FLASH(Forward). DESY hosts significant computing resources, including as a T2 for both ATLAS and CMS, and provides long established computing expertise in services such as dCache.
