2. – Last STAP meeting

3. Last STAP report actions
Plan for experiments at
HIPPO – texture evaluation
iMATERIA – combination of SANS and diffraction
Engin-X – strain scanning (good to try)
Experiments at V20 (ESS tof testbeamline)
Detector testing
First trials to mimic multiplexing (also gain experience in Mantid for data reduction)

4. Diffraction on Fe-powder (@90° @V20, WFM-mode)
measured:
simulated
(McStass):
Reduced data:
WFM-mode:
after WFM-stiching:

Sample transport to the cave
Transportation platform will be available (2x1 m)
Main door 2.2x2 m (HxW) (Takumi 1.2x2 m)
Rear cave ceiling opening 4.8x2.5 m
New 2.5x2.5 m opening above sample stage
Takumi 4x3 m above sample but not used often – from experience is much faster using doors
Inner-crane capacity of 4 tons (Takumi 450 kg)
Floor load increased overall in the cave to 4 tons/m2
Comparing with Takumi because it has also closed cave design.

6. Cave Current Activities: design of sample tower
transportation platform design
collimators
shielding and shutter calculations
PSS
Infrastructures (cables, cooling, …)
moving and positioning of Detectors
support structure (dimensions,
weight capacity, openings …)

7. Overview
NMX
BEER
CSPEC

8. In bunker Current Activities: cable management
support structure of choppers and guides
remote handling (RH)
Possible position of beam monitor:
- connected to chopper or in RH gap

9. Access Dates for NSS IK partners

10. Access Dates for NSS IK partners

11. Timeline Installation schedule is downstream – from cave to bunker!
Cave & hutch
Currently detail design in progress
Ready in the end of June
Potential delays due to the electrical design – lot of interfaces
Guide shielding and safety shutter
Currently calculations and detail design in progress
Potential delays due to the complex PSS integration and workflow
High risk connected to the budget constrains – storage capacity needed

12. Timeline

13. Timeline Guides Preparing tender for detail design in progress
Scheduled to be ready by the end of October
Manufacturing should start as early as possible (beginning of 2019)
High risk connected to the budget constrains – storage capacity needed

14. Timeline Detectors Concept tested 3He free MWPC demonstrator in design
Support structure in design
Choppers
Tender in preparation
Neutron Optics in bunker
Tender in preparation
Delays possible due to pending contracts with ESS

15. Timeline Cold commissioning: Proposed: Mid/End 2021 – Begin/Mid 2022
Beam on Target:
Expected: Mid 2022
Hot commissioning
Start of User Program:
Proposed: End 2024
