Penetrating radiation impact on NIF final optic components

Goal of the National Ignition Facility (NIF) is to achieve thermonuclear ignition in a laboratory environment in inertial confinement fusion (ICF). This will enable NIF to service the DOE stockpile stewardship management program, inertial fusion energy goals, and advance scientific frontiers. All of these applications will make use of the extreme conditions that the facility will create in the target chamber. In the case of a prospected 20 MJ yield scenario, NIF will produce 10{sup 19} neutrons with DT fusion 14 MeV energy per neutron. There will also be high-energy x rays as well as solid, liquid, and gaseous target debris produced either directly or indirectly by the inertial confinement fusion process. A critical design issue is the protection of the final optical components as well as sophisticated target diagnostics in such a harsh environment

Neutron and gamma irradiated optical property changes for the final optics of the National Ignition Facility

Based on studies the authors have performed with several radiation sources such as pulsed nuclear reactors, they have been able to construct a physical picture and measure quantitative parameters necessary to model the radiation-induced losses expected for fused silica and fused quartz National Ignition Facility (NIF) target area. It is important to note that these surrogate radiation sources do not have identical temporal and spectral characteristics to NIF, therefore caution is in order since the results obtained to date must be extrapolated somewhat to predict NIF performance

Adaptive coordination in distributed and dynamic agent organizations

We elaborate the rationale and design of OJAzzIC (OrganizationsJoining Adaptively with Improvised Coordination), a model foragents in (Jazzy) Organizations that need to engage in dynamic adaptationto respond to a dynamic situation. OJAzzIC provides an adaptivedata structure and framework for creation of multiple instances of organizationswithin a distributed system, with knowledge sharing acrossorganizational boundaries achieved through overlapping instances. © Springer-Verlag Berlin Heidelberg 2012

Design of forces driving adaptation of agent organizations

The final publication is available at Springer via http://dx.doi.org/ 10.1007/978-3-319-07551-8_10Adaptation is an important feature of human organizations. Being able to change allows them not only to survive, but to evolve to get new advantages from new situations happening in their environment or from inside the organization. The same way human organizations do, agent organizations should be able to adapt. Even if adaptation is addressed in the literature, it lacks the ability to clearly manage the reasons for change. These reasons are known in the social science bibliography as forces that drive the organizational change. These forces were introduced in a previous work in the computational domain, but only for the analysis phase of the engineering of agents organizations. In this work, a set of templates is presented to define these forces at design time. These templates have been applied in the design of components for detecting the ‘obtaining resources’ force, which have been implemented using Jason agents and CArtAgO artifacts within an agent organization.This work is supported by the MINECO/FEDER grant TIN2012-36586-C03-01, the TIN2009-13839-C03-01 project of the Spanish government, and CONSOLIDER-INGENIO 2010 under grant CSD2007-00022.Esparcia García, S.; Boissier, O.; Argente Villaplana, E.
