This proposal aims at implementing a new access route to the ESRF structural analysis capacities for the Heritage Science community. The upgrade to the ESRF-EBS was the triggering element to propose a single block allocation group (BAG). After discussion with multiple interested research teams, it was decided to target two complementary analytical configurations at the ESRF: High angular resolution XRD (ID22) and High lateral resolution XRD (ID13). The combination of these two beamlines generates precious clues on the origin, processing and degradation of historical materials. The new analytical capacities of the EBS, combined with an optimized access route is expected to increase the output of the Cultural Heritage community, to reinforce a scientific network of expert users structured around the ESRF, and to initiate new European collaborations in Heritage Science.
