1. Welcome & Charge for the Meeting
Spectroscopy STAP Meeting
ESS, 25th of September 2018
Ken Andersen, Neutron Instruments Division, European Spallation Source ERIC

2. Welcome! We are now on a regular schedule
2 STAP meetings per year, synchronised with SAC meetings
Reporting to SAC meeting
Spring: short video meeting
Autumn: longer physical meeting

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. What has happened since last time
Schedule rebaselining
Project funding
Partner countries committed to finding missing funding
Common shielding project
Bunker project
CDR in October
13 instruments passed TG2 so far
TAs are progressing slowly
ESS-ILL user meeting
10-12/10/2018

5. Rebaseline schedule for NBI. Installation (TG4 –> TG5) (V4
Rebaseline schedule for NBI* Installation (TG4 –> TG5) (V4.0, 11th May 2018) from Installation workshop with teams building first 8 Instruments (8th May)
NSS access to E01
Start User Program (3NBI*)
Beam on Target
NSS access to D01
NSS access to D03
8 NBI* in User Program
Cave installation & fitout
OOB Guides & shielding
In bunker installation
Cold commissioning
NSS access to E02/2
Float for R-BOT:
TBL ~ 21 weeks
BEER ~ 7 weeks
CSPEC & BIFROST ~ 4 weeks
MAGIC & ESTIA ~ 1 week
NSS has no float for R-SOUP, but does have possible candidates
Manufacturing on critical path for BEER, C-SPEC, BIFROST & MAGIC, not E01 access.
West sector
Parallel installation in and out of bunker is assumed for LOKI, ODIN, DREAM & ESTIA. Extra labour & resources are needed
North sector
East and South sectors
* NBI = Neutron Beam Instrument

6. Rebaseline schedule for Neutron Beam Instruments (V4
Rebaseline schedule for Neutron Beam Instruments (V4.0, 11th May 2018) from Installation workshop with teams building first 8 Instruments (8th May)
Preliminary Design
Detailed Design
Manufacturing & Procurement
Installation & Integration
Hot Commissioning/Early science
Operation
West sector
North sector
East and South sectors
Current date
First access to NSS bldgs (E01)
Start User Program (3NBI*)
BOT & start HC of NBI*
8NBI* in User Program
Safest instrument choices to be Ready for SOUP in West sector (BEER, CSPEC, BIFROST & MAGIC) & East (ESTIA)
Most desirable instrument choices for early science highlights are in the South and North (ODIN, DREAM & LOKI). LOKI seems unlikely to make the deadline
Selection of first NBI for SOUP in March 2023
Knock-on delays to NBI: – 15 of ~ 1 yr and – 22 of ~ 1 ½ yr
* NBI = Neutron Beam Instrument

7. Common Shielding Project
Phase 1: concept development (mechanical & neutronics), costing and delivery plan – until December 2018
Phase 2: manufacturing and installation at ESS
8 Instruments participating in phase 1:
BIFROST, CSPEC, T-REX, VESPA, DREAM, HEIMDAL, MAGIC, ODIN
D01/D03
E02

8. Highlight actions resulting from May SAC meeting
Continue organising STAP meetings synchronised with SAC meetings
Draft capability gap analysis
To guide choice of instruments 16-22
Demonstrate that instrument project plans are aligned with DMSC and SAD project plans
Particular focus on delivery during commissioning and early-science phase

9. Charge for the STAP
To what extent is instrument progress consistent with the schedule?
To what extent are the instruments on track for delivering early science?
To what extent are the plans for technical and scientific hot commissioning suited for delivering early science?
To what extent are the instrument project plans aligned with the plans of DMSC and SAD?
Comment on and suggest improvements to the capability gap analysis

10. Thank you!
