1 Neutron Optics Assembly NOA (Neutrons) for BEER / ESS - in 3 Lots

Kurze Beschreibung

1 Neutron Optics Assembly (NOA) for BEER / ESS, Lot 1 - 3
The European Spallation Source (ESS) ERIC (European Research Infrastructure Consortium) as joint European project is a large scale, multinational research facility being built in Lund, Sweden, with a data management and software centre in Copenhagen, Denmark.
The European Commission has, by decision (EU) 2015/1478 of 19 August 2015, established ESS as responsible for constructing, operating, developing and decommissioning the Facility.
The Swedish and Danish Governments have agreed to host ESS with Sweden as the host member state in accordance with Regulation (EC) No 723/2009.
The facility will be a world-leading centre for materials research and life sciences using neutrons and will host the world"s most powerful neutron source.
BEER is a time-of-flight engineering diffractometer being built at the ESS.
BEER is intended to enable studies of condensed matter by observing the scattering of thermal or cold neutrons by a specimen.
The unique feature of BEER will be that a large number of short pulses are extracted from the long pulse of the ESS, which is unique after its completion, resulting in significantly higher neutron flux at the sample and thus higher intensity and broader resolution range while providing comprehensive detector coverage.
The Neutron Optical Assemblies (NOA) make part of the beam transport and conditioning system:
The NOA in the common ESS bunker are responsible for the efficient extraction of the neutrons from the cold and thermal ESS moderators as well as their efficient transport through the common ESS bunker.
The neutron optical assemblies shall be installed inside the bunker and the bunker wall, respectively.
In this context Hereon is issuing a tender for the neutron optics assemblies (NOA) in the common ESS bunker. It consist of the four parts divided into three lots:
1. The Bridge Beam Guide Optical assembly
(BBGOA) and the in-bunker neutron optic
assembly (IBNOA)
2. The bi-spectral switch assembly (GSW)
3. The bunker wall insert (BWI)
The Scope of Work includes all necessary tasks and deliverables for the operation of the NOA as defined in the requirement specification:
Lot 1 - 3:
I. Preliminary Design
II. Design
III. Production and assembly
IV. Factory acceptance tests (FAT)
V. Delivery to ESS storage facility
just IBNOA (part of Lot 1) and Lot 2:
VI. Installation and alignment within the common ESS bunker
just Lot 3:
VI. Assembly and alignment of the BWI optics +
vacuum units
Lot 1 - 3
VII. Site acceptance test (SAT) of the complete
systems at ESS
VIII. Documentation in electronic and paper
copy, including quality assurance
