Welcome Update on ESS Construction Project Spectroscopy STAP

Welcome Update on ESS Construction Project Spectroscopy STAP Meeting 13 th of April 2018 Ken Andersen, Neutron Instruments Division, European Spallation Source ERIC

Welcome! • This is a test! – we are trying a video-conferencing format for some STAP meetings – two STAP meetings per year, synchronised with SAC meetings 2

Purpose and Remit of Instrument STAPs • Scientific and Technical Advisory Panels – one per instrument class • STAP: instrument advisory body – science case and functional requirements – all aspects which impact on scientific output of instrument (not just instrument project) – technical and project decisions – early science • Advice to both NSS management and instrument teams – collaborative & non-adversarial setting – NSS management & instrument teams take advice constructively – allows NSS management & instrument teams to make good, informed decisions • Each STAP meeting results in written recommendations – followed up in subsequent meeting(s) – presented at following SAC meeting 3

Re-baselining in Progress • Delays to Conventional Facilities (CF) – changes imposed by Swedish Radiation Protection Authority (SSM) on dealing with earthquake requirements – redesign of target and instrument buildings delaying CF construction by 1 -2 years • Timeline – – – – Preliminary dates communicated to instrument teams in December additional information on instrument installation provided integrated installation plan presented at IKON 14 13 -15/2 updated CF dates received early March instrument schedule integration workshop 8 th May SAC meeting 3 -4/5 external review 22 -24/5 Council meeting in June: new baseline approved 6

Science Directorate re-baseline proposal (based on CF building access dates of 5 th March) A. Three user instruments be ready to start operation by end of 2023. Preferred First instruments to be: DREAM, ODIN & LOKI (+ Test Beam Line), B. First eight instruments ready to start operation by end of 2024. Add BEER, CSPEC, ESTIA, MAGIC & BIFROST to User Program C. All fifteen instruments ready to start operation by end of 2026. Add 7 more instruments to User Program over next two years Major schedule delays: Beam on Target Beam on 1 st Instrument Eight Instrument into User Program NSS project completion Preserved milestones: Start of user program (SOUP) in 2023 NSS project completion in 2025 = 21 months = 17 months = 16 months < 12 months (with zero float) (also with zero float). 7
