This proposal is a continuation of the HG-213 and HG-172 BAG pexperiments, 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). Two complementary analytical configurations are used in the BAG: 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. By relying on the new analytical capacities of the EBS combined with optimized access route, sample preparation procedures and processing pipelines, the Heritage BAG has proven to be a very efficient way 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.
