Radiation Hardening, Reliability and Redundancy
2018There are at least three factors that affect spacecraft orbit life. These are (1) the amount of radiation protection provided for the orbit altitude of the spacecraft, (2) the reliability of the components and of the spacecraft system and (3) the redundancy built into the spacecraft.

Radiation hardening of silicon detectors
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1999Abstract The radiation hardness of high grade silicon detectors is summarized in terms of an increase of the diode reverse current, evolution of the full depletion voltage and charge collection efficiency. With the aim of improving their radiation tolerance, detectors have been produced from non-standard, float-zone silicon containing various atomic ...

Radiation-Hardening Static NMOS Rams
IEEE Transactions on Nuclear Science, 1979The results of an effort to total-dose radiation harden N-channel static random-access-memories are described. Both an aluminum-gate and a silicon-gate process were hardened to a level greater than 104 rads(Si) on a semiconductor memory vendor's production line.

A Radiation-Hardened Structured ASIC
EDFA Technical Articles, 2006Abstract Government and military ICs, like their commercial counterparts, are subject to ever-tightening cost, performance, and time-to-market demands. They must also comply with strict lifetime, reliability, and radiation hardness standards.

Radiation Hardening of Diagnostic Components
1996The peculiarity of the diagnostic system in fusion reactor in particular consist in rather hard radiation environment for some diagnostic components located near the plasma. Intense fluxes of neutron and gamma radiation can result in electric property degradation of conductors and insulating materials, in the change of optical properties of lenses ...
