Flexible Residential Test Facility: Impact of Infiltration and Ventilation on Measured Cooling Season Energy and Moisture Levels

Air infiltration and ventilation in residential buildings is a very large part of the heating loads, but empirical data regarding the impact on space cooling has been lacking. Moreover, there has been little data on how building tightness might relate to building interior moisture levels in homes in a hot and humid climate. To address this need, BA-PIRC has conducted research to assess the moisture and cooling load impacts of airtightness and mechanical ventilation in two identical laboratory homes in the hot-humid climate over the cooling season.

An Electron Beam Test Facility (EBTF) for TA-53

A dedicated facility for electron-beam R&D would significantly increase the viability of the Accelerator and Electrodynamics capability at LANL. Such a facility would provide access to a high-quality source of nearly-relativistic electrons, sufficient experimental and data acquisition capabilities, and flexibility to enable a broad range of fundamental and applied accelerator and beam physics experiments. Such a facility would cost-effectively meet the needs of a broad set of projects and sponsors ranging from LANL LDRD, DOE Office of Science, NNSA Global Security, Threat Reduction, and others. Implementation of such a facility at TA-53 would allow technical resources for Accelerator and Electrodynamics capability development to remain within LANL while meeting many important mission needs that can only be met through such a facility, allowing technical capability and technical expertise to co-reside.

Multidisciplinary Research and Development at the Dual-Axis Radiograph Hydrodynamic Test Facility (DARHT) [Slides]

DARHT is the nation’s premiere flash radiography facility. Flash radiography allows interior views of complex structures that are rapidly moving. DARHT is used to image the implosion of mock weapon assemblies containing surrogate materials. DARHT is the only dual-axis facility in the nation enabling 3D reconstructions, with multi-pulse capability for multiple time points. DARHT is an essential facility for Science-based Stockpile Stewardship at LANL and within the NNSA complex.
