WORK PACKAGE 4: Innovation of key neutronic technologies: Detectors and Moderators
TASK 4.5: Moderator testing and development beamline

2. Overview of WP4 Task 4.5
Aims of Moderator testing and development beamline (TBL)
provide design information for energy sensitive imaging of the ESS moderator
perform test experiments at BRR on TBL component prototypes
ensure design flexibility for further use of TBL beyond moderator commissioning
assess operation safety and minimum interference with neighboring beamlines

3. Deliverables
D4.4. Report on the engineering design of the BRR low dimensional moderator
Due month: 12
Status: completed
D4.7. Report on the conception design of the ESS and the BRR test beam-line
Due month: 19
ESS TBL design (subcontracted) ready for CDR
D4.15. Final verification of BRR moderator
Due month: 36
Status: prepared, no delay foreseen
The new BRR compact cold neutron moderator is unlikely to be ready for tests by the end of the BrightnESS project. Instead, thorough characterization of the existing moderator is proposed, and full operation tests of the ESS TBL prototype components.
Test environment design completed, preliminary tests performed at BNC.

5. D4.7. ESS moderator Test Beamline geometry

6. D4.7. ESS moderator Test Beamline layout, prepared for CDR

7. D4.7. ESS moderator Test Beamline layout, prepared for CDR

8. MS21. Verification of ESPI (energy sensitive pinhole imaging) setup

9. Next steps
Prepare test methodology and environment for TBL component prototype characterization, perform the experiments, process the obtained results and deliver the reports (D4.15, MS26 and MS28).
Test and characterize the very high flux tolerant detector (solid boron converter, two layer, orthogonal construction) prototype as fallback solution for TBL.
Risk factors in achieving these deliverables: unforeseen delays in production of TBL component prototypes. Unforeseen and unlikely non-availability of BNC beamlines. Mitigation: thorough mechanical and automation FAT, pre-manufacturing neutron tests of critical materials, final neutron tests at ESS.
