The Radiation, Electrical and High Energy Density Science Research Foundation seeks to advance science and engineering in the areas of radiation effects sciences, electromagnetics, high energy density science, and pulsed-power science and technology to address critical national security issues
Why our work matters
We address several issues key to nuclear security and maintaining a safe, secure, and effective nuclear stockpile. For example, radiation effects science ensures that engineered systems are able to operate as intended in the radiation environments they encounter. In addition, high energy density science validates models that are used to certify the performance of the stockpile, while pulsed-power science enables terawatt to petawatt pulsed-power systems. Such systems efficiently deliver electrical energy — in pulses that are flexible in shape and duration — to a variety of loads.
Our unique value
Advanced pulsed-power and radiation-effects facilities allow for cutting-edge research and vital national security applications:
- The Z machine uses the high magnetic fields associated with high electrical currents to produce high temperatures, high pressures, and powerful soft X-rays for research in high density physics. The Saturn X-ray source simulates the radiation effects of nuclear countermeasures on electronic and material components.
- The High-Energy Radiation Megavolt Electron Source (HERMES) III accelerator is the world's most powerful gamma simulator, primarily used to demonstrate the effect of gamma-ray radiation.
- The Annular Core Research Reactor (ACRR) is used for reactor-driven laser experiments, space reactor fuels development, pulse reactor kinetics, reactor heat transfer and fluid flow, electronic component hardening, and explosive component testing. The ACRR is also routinely used for education and training programs.
