The accelerator mass spectrometer was built by High Voltage Engineering Europe (HVEE) and set up at the Institute of Nuclear Physics at the University of Cologne.

After refurbishment at the Insitute of Nuclear Physics during 2010, the accelerator mass spectrometer was delivered in May 2010. After the successful passage of the acceptance tests, the inauguration of the CologneAMS center at the University of Cologne took place in 2011. By the end of 2011 14C measurements were running routinely. During 2012 the measurements of 10Be and 26Al were added to the routine. The routines for 244Pu and 36Cl measurements were successfully implemented. 

The accelerator facility is not only open to researchers of the University of Cologne, but can also be used by external scientists.Funding of the facility is provided by the DFG as well as the University of Cologne. Additional funds for develoopment and improvement were provided by the Deutschen Geoforschungszemtrum Potsdam (GFZ) within the framework of a cooperation contract.
