Danfysik is a Danish developer and manufacturer of particle accelerators for scientific research and medical usage, specialized magnets and particle accelerator power supplies.

History
The company was founded in 1964 by Ejnar Jespersen in Jyllinge. In 1974 it started selling synchrotron magnet systems.

In 2004 Siemens took over the medical particle therapy division of Danfysik. In 2009 Danfysik was bought by the Danish Technological Institute (DTI) and most of the company was moved to a building at DTI's campus. In 2011 the site in Jyllinge was closed.
