Two pairs of Radial Collimator for Neutrons with 2 different parameter sets (2 + 2pcs.)
for BEER / ESS (ERIC)
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 Radial Collimators are located inside the experimental Cave of BEER between the sample position and the neutron detectors.
They define together with a slit system in front of the sample (not part of the scope of supply) the gauge volume of the samples.
In this context Hereon is issuing a tender for two pairs of Radial Collimators, i.e. 4 collimators in total with two different sets of parameters.
The scope of work includes all necessary tasks and deliverables for the operation of the Radial Collimators, defined in a requirement specification:
I. Preliminary Design
II. Design
III. Production and assembly
IV. Factory acceptance tests (FAT)
V. Delivery to ESS storage facility
VI. Site acceptance test (SAT) of the complete
systems at ESS
VII.Documentation in electronic and paper
copy, including quality assurance
documentation.

The Radial Collimators are located inside the experimental Cave of BEER between the sample position and the neutron detectors. They define together with a slit system in front of the sample (not part of the scope of supply) the gauge volume of the samples.
In this context, Hereon is issuing a tender for two pairs of Radial Collimators, i.e. 4 collimators in total with the following sets of parameters.
1. Sample to Collimator length R1=276 mm, Collimator length R2=350mm, Gauge width Wg=1.00mm, Detector size in 2m distance to sample 1m x 1m.
2. Sample to Collimator length R1=482 mm, Collimator length R2=350mm, Gauge width Wg=4.00mm, Detector size in 2m distance to sample 1m x 1m.
