Status of the Robinson Wiggler project at the metrology light source

The Metrology Light Source (MLS), situated in Berlin (Germany) is owned by Physikalisch-Technische Bundesanstalt and was built / is operated by Helmholtz-Zentrum Berlin. It is an electron storage ring operating from 105 MeV to 630 MeV and serves as the national primary source standard from the near infrared to the extreme ultraviolet spectral region. The lifetime at the MLS is dominated by the Touschek effect. By installing a Robinson Wiggler, the bunches can be lengthened, as damping is transferred from the longitudinal to the horizontal plane. A considerable increase in lifetime seems achievable, while preserving the source size. The current status of this project will be presented.
