An experience exchange workshop for staff of EUCALL facilties, during which the operators of each user facility exchange information about their standard practices. This was foreseen to be of particular interest for the under-construction RIs who can define their user access policies based on practices at currently operational facilities such as DESY or ESRF. The proposed content for this workshop was generated by ELI management, who will be responsible for building up the future User Offices; and developed by EUCALL WP3 members. Topics included “Calls for Proposals”, “User Portal”, “Safety Training of Users, and Safety Staff”, “Publication Database” and “Joint Access Policies”. Invited speakers were User Office experts, data handling experts, safety officers and librarians from EUCALL RIs, as well as from some external facilities at the recommendation of the ELI management (CERIC-ERIC (IT), STFC (UK), LCLS (USA)).
