Designing a reliable target is already challenge for MW-class facilities today and has led several major accelerator to operate at lower than design power due concerns. With present plans increase beam next generation in the decade, timely R D support of robust high targets critical secure full physics benefits ambitious upgrades. A comprehensive program must be implemented address many complex challenges faced by multi MW intercepting devices. This roadmap envisioned helpful DOE-OHEP office...
The lithium collection lens is a high current (greater than 0.5 MA), pulsed device used to focus antiprotons just downstream of the production target. Pre-mature failure these lenses has led extensive efforts, understand cause failures. One main unknowns structural behavior under such extreme loading conditions. Lithium can be categorized as soft or "plastic" solid with relatively low modulus elasticity and yield strength. Very little available on its nonlinear viscoplastic (rate dependent)...
A foil of a metastable β Titanium alloy Ti-15V-3Cr-3Sn-3Al was irradiated at the J-PARC neutrino experimental facility with 1.4 × 1020 30 GeV protons low temperature (100–130°C most), and microstructural characterization hardness testing were conducted as an initial study on radiation damage effects by high energy proton beam exposure. Expected center is about 0.06–0.12 displacement per atom. density (> 1023 m−3) nanometer-sized precipitate observed TEM studies, which would be identified...
In search of a low-Z pion production target for the Long Baseline Neutrino Facility (LBNF) Deep Underground Experiment (DUNE) four graphite grades were irradiated with protons in energy range 140--180 MeV, to peak fluence $\ensuremath{\sim}6.1\ifmmode\times\else\texttimes\fi{}{10}^{20}\text{ }\text{ }\mathrm{p}/{\mathrm{cm}}^{2}$ and irradiation temperatures between $120--200\text{ }\ifmmode^\circ\else\textdegree\fi{}\mathrm{C}$.

A high-strength dual alpha+beta phase titanium alloy Ti-6Al-4V is utilized as a material for beam windows in several accelerator target facilities. However, relatively little known about how properties of this are affected by high-intensity proton irradiation. With plans to upgrade neutrino facilities at J-PARC and Fermilab over 1 MW power, the radiation damage window will reach few displacements per atom (dpa) year, significantly above ~0.3 dpa level existing data. The RaDIATE collaboration...
As beam power continues to increase in next-generation accelerator facilities, high-power target systems face crucial challenges. Components like windows and particle-production targets must endure significantly higher levels of particle fluence. The primary beam's energy deposition causes rapid heating (thermal shock) induces microstructural changes (radiation damage) within the material. These effects ultimately deteriorate components' properties lifespan. With conventional materials...
Beryllium is a material extensively used in various particle accelerator beam lines and target facilities, as windows and, to lesser extent, secondary production targets. With increasing intensities of future multimegawatt these components will have withstand even greater thermal mechanical loads during operation. As result, it critical understand the beam-induced shock limit beryllium help reliably operate without having compromise efficiency by limiting parameters. part RaDIATE (radiation...
Novel beam-intercepting materials and targetry concepts are essential to improve the performance, reliability operation lifetimes of next generation multi-megawatt (multi-MW) accelerator target facilities. The components must sustain an order-of-magnitude increase in particle beam intensities beyond current state-of-the-art. With conventional already limiting scope experiments, it is crucial investigate novel materials, technologies that will satisfy requirements maximize physics benefits...
A comprehensive study on the effects of energetic protons carbon-fiber composites and compounds under consideration for use as low-Z pion production targets in future high-power accelerators low-impedance collimating elements intercepting TeV-level at Large Hadron Collider has been undertaken addressing two key areas, namely, thermal shock absorption resistance to irradiation damage.
