Within the scope of WP8[1] in the EU project SINE2020[2], our collaboration has worked on multiple tasks to pave the way for future European neutron sources:

1. New methods (e.g. MCPL[3]) have been developed for realistic source-to-end simulations of instruments, based on both neutronics (e.g. MCNP[4]) and Monte Carlo ray-tracing (e.g. McStas[5], SIMRES[6] and Vitess[7]).
2. New equipment has been developed to assess background generated by high-energy particles from modern spallation sources and new types of shielding[8] [9] have been developed to suppress these backgrounds and improve signal to noise. Short and longer term effects of irradiation have further been assessed.
3. Effective parameters to enable compact, modular Larmor-based devices for the ESS have been derived[10].

On behalf of the international collaboration, the presentation will highlight the main results

achieved in SINE2020 WP8.
