The European Spallation Source (ESS) represents one of the most ambitious scientific infrastructure projects in Europe, bringing together a wide community of institutes, funding bodies, and experts to deliver the next generation of neutron science. Among the key subsystems enabling world-class performance are the neutron chopper systems — over 100 precision-engineered devices designed to...
The H15 neutron guide at the ILL is a complex system delivering neutrons to 5 new or fully renovated instruments.
Due to its dimensions, in particular before the first split,the reduced places for the instruments and their demands in terms of beam conditioning (polarization, monochromators, chopper systems, etc.), the installation process has been full of surprises. Reactivity and quick...
Neutron Instruments on spallation sources have very particular environmental conditions in their instrument zone. Typically vacuum and radiation requirements are not as demanding as on applications at other radiation facilities like synchrotrons or inside reactors. Even with high flux sources some well selected standard industrial motion components like motors, switches, cables and connectors...
- The Argentinean Atomic Energy Commission (CNEA) is building a multi-purpose research reactor in Centro Atómico Ezeiza, 30 km from Buenos Aires Argentina, with commissioning planned for mid 2020. The RA-10 will be an open-pool facility for radioisotope production, materials and fuel irradiation, silicon doping and neutron techniques applications. Associated to this last goal there is a...
After more than two decades of operation, the POLDI instrument (Pulse Overlap Time-of-Flight Diffractometer) at PSI is undergoing a comprehensive upgrade. This transformation encompasses the entire system — from the instrument and neutron guide to the surrounding infrastructure, motion systems, and detector control — effectively amounting to a complete rebuild.
While the project has made...
Neutron Guide Systems serve a central purpose in the functioning of an instrument. While the guides are high-tech assemblies purpose built for each beamline, their supporting systems are less cutting edge and more structural engineering.
This presentation aims to demonstrate the importance of supposedly overbuilding the guide support assemblies to facilitate smoother installation and...
The design and engineering of neutron scattering instruments are essential to advancing research in materials science, chemistry, biology, and condensed matter physics. In Europe, a distributed network of large-scale neutron facilities—such as the Institut Laue-Langevin (ILL), the European Spallation Source (ESS), and various national research centres—has fostered decades of innovation and...
