Wiggler (synchrotron)
A wiggler is an insertion device in a synchrotron. It is a series of magnets designed to repeatedly laterally deflect ('wiggle') a beam of charged particles inside a storage ring of a synchrotron. These deflections release synchrotron radiation. Although synchrotrons give off such radiation anyway as magnets work to bend the particles on a circle-like path, a wiggler release more intense radiation than the bending magnets.
