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

2. 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

3. 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

4. Construction and Operations Budgets
Initial Operations
Steady-State Operations

5. Current Baseline Instrument Ramp-up

6. 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 /2
updated CF dates received early March
instrument schedule integration workshop 8th May
SAC meeting 3-4/5
external review 22-24/5
Council meeting in June: new baseline approved

7. Science Directorate re-baseline proposal (based on CF building access dates of 5th March)
Three user instruments be ready to start operation by end of 2023.
Preferred First instruments to be: DREAM, ODIN & LOKI (+ Test Beam Line),
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 = 21 months
Beam on 1st Instrument = 17 months
Eight Instrument into User Program = 16 months
NSS project completion < 12 months
Preserved milestones:
Start of user program (SOUP) in (with zero float)
NSS project completion in (also with zero float).
