Hexapod and Rotary Stage for BEER / ESS

Kurze Beschreibung

1 Hexapod and Rotary Stage for BEER / ESS
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 Hexapod and the Rotary Stage are part of the Sample Stage Assembly for BEER / ESS.
The Sample Stage Assembly is responsible for the precise positioning and movement of samples and sample environment equipment into the neutron beam.
It is located in a pit within the experimental Cave of BEER and consists of an adapter plate, the Rotary Stage and the Hexapod.
The adapter plate will be provided by Hereon while the Rotary Stage and Hexapod are subject to the Contractor.
In this context Hereon is issuing a tender for the Hexapod and Rotary Stage
The scope of work includes all necessary tasks and deliverables for the operation of the Rotary Stage and the Hexapod as defined in the requirement specification:
I. Preliminary Design
II. Design
III. Production and assembly
IV. Factory Acceptance Tests (FAT)
V. Delivery to ESS storage facility
VI. Installation and alignment within the
experimental Cave
VII. Site Acceptance Test (SAT) of the complete
systems at ESS
