A high-power target system is a key beam element to complete future High Energy Physics (HEP) experiments.
In the recent past, major accelerator facilities have been limited in beam power not by their accelerators, but by the beam intercepting device survivability. The target must then endure high power pulsed beam, leading to high cycle thermal stresses/pressures and thermal shocks. The...

High-Entropy Alloys and Electrospun Nanofiber materials are two novel classes of materials that can offer improved resistance to beam-induced radiation damage and thermal shock. Research to develop these new materials specifically for multi-megawatt accelerator target applications, such as beam windows and particle-production targets, are ongoing at Fermilab, within the scope of a DOE Early...

47. Computational Exploration of High Entropy Alloys as Promising Materials for Future Beam Windows

Contributed Oral

Beam power and runtime in high energy particle accelerators face limitations due to targets and beam windows, experiencing thermal shock, fatigue, and irradiation damage from the beam. To achieve higher beam power and extended runtime, the development of new materials is crucial, with High Entropy Alloys (HEAs) emerging as a promising solution due to their exceptional properties, including...

100. Evaluation of β-phase based titanium alloys

Contributed Oral

Titanium materials have been applied to beam window materials and beam dumps in large accelerator systems because of their low specific gravity, high corrosion resistance, strength, and other advantages. As beams become more powerful, there is a growing demand for higher irradiation resistance and other properties. We have been further characterizing titanium alloys based on the β-phase, and...
