Characterizing and Mitigating Radiation Effects in Inertial Fusion Energy Devices

Inertial Fusion Energy (IFE) systems operate in a demanding environment with intense, pulsed radiation fields. A comprehensive understanding and characterization of the effects is necessary to ensure the survivability of components. This presentation will explore key radiation interaction phenomena that are especially pertinent to IFE. We will cover methods for evaluating transient threats, including the use of laser impulse measurements to gain insight into the potential magnitude of X-ray-induced shock effects and ways to test materials, the physics and impacts of Electromagnetic Pulse (EMP) on the system, as well as the long-term degradation caused by Total Ionizing Dose (TID) and the widespread effects of the neutron environment on the reliability of electronic components. This overview seeks to lay a strong foundation, illustrating why an in-depth investigation of these radiation effects is essential for predicting system responses and creating effective mitigation strategies for operational IFE systems.
