Beam-Induced Damage Mechanisms and their Calculation

A. Bertarelli


The rapid interaction of highly energetic particle beams with matter induces dynamic responses in the impacted component. If the beam pulse is sufficiently intense, extreme conditions can be reached, such as very high pressures, changes of material density, phase transitions, intense stress waves,
material fragmentation and explosions. Even at lower intensities and longer time-scales, significant effects may be induced, such as vibrations, large
oscillations, and permanent deformation of the impacted components. These lectures provide an introduction to the mechanisms that govern the
thermomechanical phenomena induced by the interaction between particle beams and solids and to the analytical and numerical methods that are available for assessing the response of impacted components. An overview of the design principles of such devices is also provided, along with descriptions
of material selection guidelines and the experimental tests that are required to validate materials and components exposed to interactions with energetic
particle beams.
