Why Does Titanium Alloy Beam Window Become Brittle After Proton Beam Exposure ? -Research and Development on the Accelerator Target and Beam Window Materials by RaDIATE International Collaboration-
●A high-strength titanium alloy Ti-6Al-4V is widely employed as the “beam window” at high-intensity proton accelerator facilities, such as FNAL and J-PARC. However, this alloy suffers from radiation- induced hardening…
