Operation of a five‐pole superconducting wiggler in the DCI positron ring and design of the beamline (invited)

A five‐pole superconducting wiggler has been installed in the DCI positron ring and operated without disturbing the machine characteristics at full energy (1.85 GeV) and maximum current (300 mA). Three beamlines have been built which feed six beam ports. The first two‐crystal monochromator to be used for Compton scattering has been commissioned although the sagittal focusing has not yet been tested.
