1. SKADI Current Status STAP-Meeting 30.04.2019
----- Meeting Notes ( :13) -----
Welcome
First Presentation of TG2 for SKADI
Science Case, Top Level Requirements, Cursory Overview
Construction Schedule and Risk Analysis
April 2019| Sebastian Jaksch, Romuald Hanslik, Teddy Kozielewski, Sylvain Désert, et al.

2. 13.6.7.2 Sample Exposure System Sample Area
We have prepared CTV-documents for Bunker neutron guide system (BNGS) (neutron guides and their housing).
The CTV has took at mid. of December 2018
After the first iteration we wait for the approval from ESS for the order.

3. Sample Table
In construction
Material is arriving
More from Andreas

4. Detector SONDE
Developing of housing and cooling

5. Electronics, Construction & Testing
Electronics arriving in Jülich now
Tests ongoing, so far no rejects
Production design for the housing ready beginning of May
Production foreseen until September (large components, assembly may take a little longer)
Workshop at fall IKON  Presentation of working detector from SoNDe project
Testing housing is ready
Testing in Saclay imminent (computer installation issues for full replication of ESS environment)
After that: Rollout to other facilities planned (you were contacted)
Photo of setup ready for installation

6. VSANS Long wavelengths lead to additional scattering
Effect occurs above 6 Å
Might be tolerable until 10 Å
Looking for high intensity peaks this might not be an issue

7. GISANS Feasible up to 0.4° incoming angle
Easily feasible up to 0.3° specularly reflected angle
Needs some kind of beamstop/more consideration for higher exit angles
Easy for Si substrates
Both horizontal and vertical orientation possible
Polarization not affected
Slightly restricted collimation settings, depending on incoming angle

8. Photos of first tests Multi-Angle DLS setup
Sintered vapour champer without sharp edges for GISANS

9. Thank you for your attention

11. Schedule Change: Rationals & Consequences
Adjustment to ESS/NSS Master Schedule V4.1
Earlier procurement not permitted in ESS timeline
Consequences
Neccessary installation in bunker after BOT
No early science
Project broken down into subprojects and restarted after dormant periods according to ESS request to avoid budget increase
Loki the only LSS instrument for early science
No polarized SANS until 2025
Plan 1
Plan 2

12. Aber … Die gute Nachricht ist:
JCNS Direktorium unterstützt das Projekt voll weiter
Implementierung läuft für KWS Instrumente
Dafür haben wir dann auch ab „sofort“ Neutronen
