A proton beam window is an important component in a spallation target. It guarantees the safe operation of the target, since its failure may cause severe contamination of the proton beamline and lead prolonged shutdown of the neutron source. A proton beam window is the component exposed to the highest proton beam current or intensity in the target. The high proton beam current density in a...
The solid spallation neutron source target is used in the condition of high temperature, high radiation and continuous cooling water erosion. In order to obtain a high neutron yield, the target material is generally selected from the metal material with a relatively high atomic number. Tungsten is one of the suitable choices as the spallation neutron sources solid target material due to its...
Slow neutrons, such as cold neutrons, are really important non-destructive probes not only for basic physics but also for the structural genomics advancements. Neutron-based science is also known as high-neutron-intensity-dependent science. A new unique method focusing on nanosized particle aggregation has been proposed to increase neutron intensity below cold neutron energy region. The method...
ESS Bilbao is a public consortium of the Spanish and Basque Governments. It brings knowledge and added value in particle accelerators, nuclear and neutron and scattering science and technologies by leveraging its in-kind contribution to the European Spallation Neutron Source (ESS), in Lund (Sweden). ESS is currently under construction and when operating will represent the most powerful neutron...
Recent studies [1, 2] have revealed the remarkable potential of optimized low-dimensional liquid para-H2 moderators in enhancing cold neutron brightness compared to voluminous moderators. In this research, we introduce a novel analytic approach to calculate the brightness of such moderators. Our findings demonstrate that as the brightness gain is the near-the-surface effect, the high-aspect...
The European Spallation Source (ESS) is an ambitious European project with a budget higher
to 1800 Me. The aim of the project is to design, build and operate the brightest spallation
neutron source in the world. The ESS will use a proton beam with final power deposited on the
target of 5 MW, which will impact on a tungsten Target cooled by helium gas.
The spallation reactions produced...
The ISIS Neutron and Muon Source is based at the Rutherford Appleton Laboratory in the UK and is owned and operated by the Science and Technology Facilities Council, one of the councils that forms UK Research and Innovation (UKRI). Since production of first neutrons in 1984, ISIS has continued to develop its capabilities while growing and supporting the neutron scattering and muon science...
Conceived back in 2012, the TS1 project [1] is a long-running sustainability project that set out to reinvigorate the internals of target station 1, including but not limited to the neutron target, reflector and moderators (TRaM), as well as the supporting services required to keep the TRaM components operating.
In over a decade that the project has been running, a great many things have...

On 4th November 2022, neutrons were produced on ISIS’ target station 1 (TS1) for the first time since a long shutdown began on 21st June 2021 to enable the planned work for the TS1 project [1]. Since that date in November scientists, engineers and technicians been working hard to return TS1 to a fully operational state and enable the delivery of science again.
Relatively quickly after...
