The Endurance upgrade programme covers the period 2016 – 2023 with a budget of 60 M€. About 30 projects have been delivered or are nearing completion. They include neutron guide systems, new and upgraded instruments, sample environment and data and software services. The upgrade programme as a whole ensures that research capability at the ILL will continue to be world leading for the next decade, offering new opportunities and perspectives for excellent science, both for academia and industry. The Endurance programme will be presented, including specific examples and initial results, and set in the context of future reactor operation, given the recent agreement by the ILL Associates to fund the Institute for the period 2024 – 2033.
