Three intense medium-energy proton accelerators are operating and available at present in the Unites States, Switzerland, and Canada. Analogous construction work at the research complex at the Moscow Meson Facility (MMF) of the Institute for Nuclear Research at the Russian Academy of Sciences (INR RAS) has been finished also. At this time, the first part of the MMF works at an energy of 400 MeV and a proton current up to 0.07 mA. The experimental investigations carried out at the meson physics facilities at Los Alamos National Laboratory and Villigen (Switzerland) have demonstrated the effectiveness of using of these accelerators for research on radiation effects in alloys. At high-energy, high-power accelerators such as TRIUMF, SIN, ISIS, and LAMPF, the environment for materials is similar to that at fusion reactors, especially in the case of internal targets and beam stops. Here, materials are subjected to a substantial fluence of high-energy particles, primarily protons and neutrons generated through spallation reactions. The high-energy particles produce higher energy primary atom recoils and damage states than do neutrons from a fission reactor environment. Transmutation atom impurity production is also substantially increased relative to a fission reactor environment. The authors now have the complementary possibility for radiation damage study at the MMF.
