Vulnerability analysis of DT fusion diagnostics for laser megajoule facility a new tool: Diacad

The development of huge laser facilities for inertial confinement fusion pushes the design of new nuclear diagnostic links to study the DT fusion. The electronic and optoelectronic equipments of these links are facing high radiative constraints due to the very short neutron and gamma pulses. We have developed a new computer-based tool to address the sensitivity to this type of environment of nuclear diagnostic links. This tool takes into account the vulnerability of individual parts and the global structure of the link. It allows to identify the weakest elements of the link, and then to feedback with hardening and/or shielding actions.
