We are pleased to announce the Topical Workshop on "Emittance Measurements for Light Sources and FELs", which will be organized by the ALBA Synchrotron between the 29^th – 31^st January 2018.

This is the first of a sub-series of workshops on "Advanced Diagnostics for Accelerators" (ADA) within the newly EU funded ARIES programme (Accelerator Research and Innovation for European Science and Society).

Experts from the scientific community working emittance measurements for electron machines (including light sources, damping rings, FELs and future e+/e- circular colliders), will gather together with to present the status of the different beam size measurements techniques; discuss the challenges that the community faces for the next generation of ultra-low emittance machines; and enhance synergies between the different communities.
