The radiation hardening is accomplished by producing electronic components incorporating several possible techniques and materials, including: using rad-hard cells in an ASIC design, using insulating substrates, such as silicon-on- insulator (SOI) or silicon-on-sapphire (SOS); or wide band gap semiconductors such as …07-Jun-2018
What are radiation hardened materials?
Radiation-hardened electronics, also called rad-hard electronics, are electronic components (circuits, transistors, resistors, diodes, capacitors, etc.), single-board computer CPUs, and sensors that are designed and produced to be less susceptible to damage from exposure to radiation and extreme temperatures (-55°C to …
What is radiation hardened design?
Radiation hardening (Johansson, 1977) is a technique to design and test electronic components and systems to make them resistant to damage or malfunctions caused by ionizing radiation such as particle radiation and high-energy electromagnetic radiation, which would be encountered in the outer space, high-altitude …
How are electronics hardened?
Radiation hardening involves designing radiation-tolerant electronics and components that are tolerant of the massive levels of ionizing radiation, such as cosmic outer space radiation, X-ray radiation in medical or security environments, and high energy radiation within nuclear power plants.
How do you shield electronics from radiation?
Covering devices with lead or aluminum can shield them from some forms of radiation. Another radiation-defense strategy involves putting several copies of a critical component onto a satellite so that if one fails, the others can pick up the slack.
How much does radiation hardening cost?
The Rad-Hard SBC offers a space-hardened, affordable single-board computer – a market segment not currently represented. The technology is smaller in size and weight, measuring less than 7 inches x 6 inches, cost, coming in around $130K, and lower power, consuming just 6.6 Watts.
Does radiation destroy electronics?
Nuclear radiation can damage electronics similar to EMP damage, if the electronics are energized. Nuclear radiation can damage electronics when not energized. Very high dose rates and very energetic radiation are needed in either case.
What is soft radiation?
Quantum radiation (particles or photons) of limited penetrating power, typically of lower frequency or longer wavelength. A 10-cm thickness of lead is usually used as the criterion upon which the relative penetrating power of various types of radiation is based.
How does radiation fry electronics?
The total ionizing dose is an accumulating effect, of the dose rate and the total time a circuit is exposed to radiation. Ionising radiation creates electron-hole pairs in the electronics, changing the transistor parameters and eventually destroying them. It can also cause leakage currents between circuits.
Can radiation destroy electronics?
Nuclear radiation can damage electronics similar to EMP damage, if the electronics are energized. Nuclear radiation can damage electronics when not energized. Very high dose rates and very energetic radiation are needed in either case.
