Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), [1] especially for environments in outer space (especially beyond low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear ...
The RAD750 is a radiation-hardened single-board computer manufactured by BAE Systems Electronics, Intelligence & Support. [1] The successor of the RAD6000, the RAD750 is for use in high-radiation environments experienced on board satellites and spacecraft. [2] The RAD750 was released in 2001, with the first units launched into space in 2005. [1 ...
Radiation hardening is the strengthening of the material in question by the introduction of defect clusters, impurity-defect cluster complexes, dislocation loops, dislocation lines, voids, bubbles and precipitates. For pressure vessels, the loss in ductility that occurs as a result of the increase in hardness is a particular concern.
When optical fibers are exposed to ionizing radiation such as energetic electrons, protons, neutrons, X-rays, Ƴ-radiation, etc., they undergo 'damage'. [1] [2] The term 'damage' primarily refers to added optical absorption, resulting in loss of the propagating optical signal leading to decreased power at the output end, which could lead to premature failure of the component and or system.
Austin, Oct. 22, 2024 (GLOBE NEWSWIRE) -- Austin, Texas - VORAGO Technologies, a leading provider of radiation-hardened and radiation-tolerant microcontrollers and microprocessors for aerospace and defense, is pleased to announce the expansion of its global partner ecosystem in support of two key industry needs – advancing edge computing for space and enhancing radiation resilience for non ...
Radiation hardening in general is an important part of spacecraft design when it is required, and the main processor of Juno, the RAD750, has been used on other spacecraft where there are elevated radiation levels, and it is a radiation-hardened microprocessor. [12]
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 electron volts (eV), which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms.
The RAD5500 is a radiation-hardened 64-bit processor core design created by BAE Systems Electronics, Intelligence & Support based on the PowerPC e5500 designed by IBM and Freescale Semiconductor. [1] [2] [6] Successor of the RAD750, the RAD5500 processor platform is for use in high radiation environments experienced on board satellites and ...
