BLIP: Aluminium Capsule

Explore the impact of radiation damage on aluminium specimens irradiated at the European Spallation Source. Detailed study includes tensile specimens and disc specimens with 2D FLUKA simulations. Learn about the beam parameters, aluminum module capsule, temperature effects, and post-irradiation examination with luminescent coating.
