Spallation neutron/muon source component, systems & materials related technology and innovation.

Oxide dispersed strengthened (ODS) ferritic/martensitic steels have been extensively studied in various fusion and fission materials R&D programs. Due to their high strength at high temperatures, ODS steels are tentative structural materials in ADS. The objective of this study is to determine irradiation-induced evolution of nano-sized clusters in ODS steels. The selected ODS steels are...

Spallation neutron/muon source component, systems & materials related technology and innovation.

As part of the CSNS-II Project, a new design of moderator and reflector plug will be installed at CSNS-II target station.
As the proton beam power will be upgraded from 100KW to 500KW, the structure and the manufacturing technology of the reflector will be optimized to accommodate the higher thermal deposition. The material 6061-T6, which has stronger resistance to stress corrosion, will be...

Spallation neutron/muon source component, systems & materials related technology and innovation.

Due to its high density, high melting point, and high thermal conductivity, W is used as a solid target material for scattering neutron sources. However, because of the poor corrosion resistance of W, it is necessary to coating a good corrosion-resistant layer to ensure the long-term use of the target material, Ta metal is a good choice and both have good applications in ISIS and CSNS.

Spallation neutron/muon source component, systems & materials related technology and innovation.

The ISIS Facility uses a Tantalum clad Tungsten target in order to produce neutrons which facilitates unique and innovative research. The properties required for a material to qualify as a potential target material are strict, resulting in scarce options. Often these materials are very expensive due to their rarity and are also very difficult to work with from a machining and manufacture...

Spallation neutron/muon source component, systems & materials related technology and innovation.

The target assembly for the Second Target Station (STS) at Oak Ridge National Laboratory is working towards final design approval in late 2025, and R&D continues to focus on the manufacturing of the target segment. The novel design of the target segment and unique combination of materials (tungsten, tantalum, copper, and Inconel) has driven the process development towards solid state bonding...

10. Alternative designs for the Beam Dump Facility (BDF) production target and in-beam test plans at CERN

Spallation neutron/muon source component, systems & materials related technology and innovation.

CERN’s upcoming Beam Dump Facility (BDF) will host a new high-Z production target. The device will act as a beam dump to safely absorb 356kW of the 400 GeV/c proton beam delivered by the Super Proton Synchrotron (SPS). At the same time, it will generate a large number of high energy particle collisions in an attempt to produce hidden sector particles for the Search for Hidden Particles (SHiP)...

45. Applying a Pressure System Safety Code to Spallation Target Design

Application of new materials data and/or safety codes, computational modelling/analysis.

The Second Target Station (STS) project at Oak Ridge National Laboratory (ORNL) has entered preliminary design review activities with an innovative edge-cooled spallation target. The tungsten/tantalum laminate spallation block is clad in copper and contained inside a thick Inconel shroud. The shroud provides structural support. It also provides thermal management by flowing water through...
