“…It is enough to install this wiggler in non-zero dispersion straight section without any need to modify the existing infrastructure. First observations have been carried out with success at Cambridge Electron Accelerator [31], and in the PS at CERN [32] showing 50% horizontal emittance reduction. RW has been recently adopted by other light sources to reduce the horizontal emittance like Heifei Light Source [33], Shanghai Synchrotron Radiation Facility [34] and the Metrology Light Source that benefited from RW to improve Touschek lifetime by lengthening the bunch [35,36].…”

The performance of synchrotron light facilities are strongly influenced by the photon beam brightness, that can be further increased by reducing the beam emittance. A Robinson Wiggler can be installed in a non-zero dispersion straight section to reduce the horizontal beam emittance. It is composed of an array of magnets of alternated polarities, whose both magnetic field and gradient are of opposite signs. It provides a compact solution to reduce by 50% the horizontal emittance. However, it increases the energy spread by 40%. The concept of the Robinson Wiggler (RW) is described here, the first experimental observation of the Robinson effect in a synchrotron light source on the transverse and longitudinal beam properties by the means of four existing undulators is presented and the impact on the photon flux density is studied.
