It is part of the Coordinated Accelerator Research in Europe (CARE) project, involves eight collaborators and is half-funded by the European Union. After briefly recalling the Activity organization, we report the main progress achieved over the last year, which includes: the manufacturing of a double-bath He II cryostat for heat transfer measurements through Nb$_{3}$Sn conductor insulation, detailed quench computations for various NED-like magnet configurations, the award of two industrial subcontracts for Nb$_{3}$Sn conductor development, the first results of a cross-calibration program of test facilities for Nb$_{3}$Sn wire characterization, detailed investigations of the mechanical properties of heavily cold-drawn Cu/Nb/Sn composite wires and the preliminary assessment of a new insulation system based on polyimide-sized fiber glass tapes. Last, we briefly review the efforts of an ongoing Working Group on magnet design and optimization.
