Book Description
Spacecraft depend on electronic components that must perform reliably over missions measured in years and decades. Space radiation is a primary source of degradation, reliability issues, and potentially failure for these electronic components. Although simulation and modeling are valuable for understanding the radiation risk to microelectronics, there is no substitute for testing, and an increased use of commercial-off-the- shelf parts in spacecraft may actually increase requirements for testing, as opposed to simulation and modeling. Testing at the Speed of Light evaluates the nation's current capabilities and future needs for testing the effects of space radiation on microelectronics to ensure mission success and makes recommendations on how to provide effective stewardship of the necessary radiation test infrastructure for the foreseeable future.

Book Description
The Space Radiation Effects Laboratory located in Newport News, Virginia, was operated by the College of William and Mary for the National Aeronautics and Space Administration (NASA). A synchrocyclotron was formerly in operation in this laboratory and a primary beam of 600 MeV protons and secondary beams of 400 MeV pions and muons were produced for the purpose of studying the effects of radiation on materials planned for use in space. The synchrocyclotron was removed in 1980. At several locations, the scattered radiation caused an induced radioactivity within the walls of the cyclotron room. A radiological survey has been performed to determine the amount of residual radioactivity on the walls. Calculations were performed to determine the thickness of the concrete walls and floor for shielding the residual radiation in the cyclotron room. Recommendations were made to minimize exposure to a potential occupant working in the building from the residual radioactivity on the walls and floor of the cyclotron room.

Book Description
A model of the radiation effects laboratory has been built to help visualize operational problems and equipment placement. A photograph of the model provides a perspective of the external features of the building. A tower houses one of the major accelerators, a Dynamitron. The second major radiation source is an electron linear ac celerator (Linac). This machine is placed in the opposite end of the building from the Dynamitron. A view is given of the model with the roof and overhead shielding removed, showing certain major features of the laboratory. Because of possible settling of the building foundation over a period of years the accelerator and test areas are separated by a specially designed corridor from the control room and support laboratory area The laboratory building has an area of approxi mately 17,000 sq. ft. and will cost approximately $800,000. The accelerator selection and the building design were made on the basis of exist ing requirements for nuclear weapon and space radiation effects testing. However, the machine and building specifications were written so that many other applications could be served. This document discusses the major features of the laboratory and presents examples of some of the work to be accomplished. (Author).

Book Description
Fulfilling the President's Vision for Space Exploration (VSE) will require overcoming many challenges. Among these are the hazards of space radiation to crews traveling to the Moon and Mars. To explore these challenges in some depth and to examine ways to marshal research efforts to address them, NASA, NSF, and the NRC sponsored a workshop bringing together members of the space and planetary science, radiation physics, operations, and exploration engineering communities. The goals of the workshop were to increase understanding of the solar and space physics in the environment of Earth, the Moon, and Mars; to identify compelling relevant research goals; and discuss directions this research should take over the coming decade. This workshop report presents a discussion of radiation risks for the VSE, an assessment of specifying and predicting the space radiation environment, an analysis of operational strategies for space weather support, and a summary and conclusions of the workshop.
