This report of the Committee on Space Radiation Effects Testing Infrastructure for the U.S. Space Program 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.

CURRENT RADIATION TESTING INFRASTRUCTURE The current infrastructure for radiation testing has the following five elements: facilities for testing, standards and guidelines that detail conditions of testing, modeling and simulation tools that predict the response of parts and systems to radiation, databases that can help minimize the duplication of test efforts, and workforce and training to ensure the ability to conduct the needed tests. Today, 15 U.S.-based facilities provide the radiation testing infrastructure required.

Databases of existing data can also help to validate the models. Radiation data are available from vendors, from NASA's Jet Propulsion Laboratory and Goddard Space Flight Center, the European Space Agency, and in various data workshops and compendia associated with conferences on radiation effects, such as the Institute of Electrical and Electronics Engineers (IEEE)

Experts conducting the tests must be familiar with radiation transport in materials, semiconductor physics, semiconductor device design, space radiation environments, and a variety of other fields. Given the rapid pace of change in electronics, continuing education through conferences, short courses, and workshops is critical to ensuring radiation analysts are familiar with the latest developments.

. The combination of this fragility and overloading of current beam-line facilities for space radiation testing, together with the growing complexity of commercially available microelectronic and optoelectronic systems that will further strain the system, and increasing requirements for accelerator testing by the private sector, all together project a growing shortage of available testing facilities to support future space missions among space agencies and industry.

Such technologies could shrink ion accelerators to table-top size, allowing greater access to high-energy ion beams and reducing beam costs.2 Recommendation: The joint coordination body should assess and support university capabilities for improving space electronics testing and development infrastructure, including the following: the devel opment of advanced accelerator concepts, improved testing strategies, improved radiation hardening solutions designs, and radiation mitigation techniques. The rapid development of semiconductor devices means that the body of knowledge for the field advances more rapidly than it can be accommodated in test standards.
