The Wiggler

A wiggler is an arrangement of magnets configured so that, when inserted into the path of a beam of particles, it affects the properties of the beam.

Suggested in 1956 by K. W. Robinson of the Harvard University Cambridge Electron Accelerator (CEA) as a way to produce synchrotron radiation, the first wiggler was built by CEA in 1966 -- but it was installed as a damping component in a beam storage system.

It wasn't until 1979, at the Stanford Synchrotron Radiation Project (SSRP -- later renamed SSRL) that a wiggler was first built and installed to be used as a synchrotron radiation source.
