HEP High Power Targetry Roadmap -- Workshop Report

Frédérique Pellemoine, Dohyun Kim, David J. Senor, Vladimir Shiltsev et autres

Designing a reliable target is already a challenge for MW-class facilities today and has led several major accelerator facilities to operate at lower than design power due to target concerns. With present plans to increase beam power for next generation accelerator facilities …

RaDIATE Collaboration for Material Studies

Frédérique Pellemoine

In the recent past, major accelerator facilities have been limited in beam power not by their accelerators, but by the beam intercepting device survivability. As next-generation accelerator target facilities (High Energy Physics, Spallation Sources, …) become increasingly more powerful and intense, high …

Measurements of displacement cross sections of metals for 120-GeV proton beam irradiation

Yosuke Iwamoto, Hiroki Matsuda, Shin-ichiro Meigo, K. Yonehara et autres

The number of displacements per atom (dpa) is widely used as an indicator of irradiation damage of materials in proton accelerator facilities. Experiments have been carried out to validate the dpa of metallic materials for protons with energies below 3 GeV. However, …

Novel Materials for Next-Generation Accelerator Target Facilities

Kavin Ammigan, Gaurav Arora, Sujit Bidhar, Frédérique Pellemoine et autres

As beam power continues to increase in next-generation accelerator facilities, high-power target systems face crucial challenges. Components like beam windows and particle-production targets must endure significantly higher levels of particle fluence. The primary beam’s energy deposition causes rapid heating (thermal shock) and …
