Radiation Hardened Silica-Based Optical Fibers

1986
Abstract : Since it is generally recognized that radiation-induced loss is due to pre-existing defects in optical fiber, the technical approaches were designed to reduce the number of these defects in as-drawn fiber and to passivate the ones that remain.

Radiation-Hardened Wafer Scale Integration

1989
Abstract : This report describes the logical and physical design of a prototype focal plane processor to be built as a wafer-scale circuit in a radiation-hard CMOS process. Design details and test results are presented for the five circuits which were fabricated in bulk CMOS through the MOSIS fabrication service.

Radiation Hardened High Speed Digitizer

2019 IEEE Aerospace Conference, 2019
Los Alamos National Laboratory has designed and demonstrated a space-flight quality digitizer board with a CompactPCI interface in the popular 6U form factor. The digitizer board is designed to meet the requirements of missions requiring true space-grade radiation tolerance in geosynchronous orbits.

Radiation-hardening of semiconductor parts

2002
Abstract ‘Radiation-hardening’ derives from military terminology (see Section 4.1). The term has acquired a wide variety of meanings, depending on the user group and radiation environment concerned. That environment may present a variety of levels of total ionizing dose, transient dose rate, neutrons, or single-event upsets.

Two Radiation-Hardened Analog Multiplexers

IEEE Transactions on Nuclear Science, 1983
A total dose radiation-resistant, high voltage CMOS process has been used to build both eight-and sixteen-channel analog multiplexers. The circuits are hardened versions of the Harris 508A and 1840 dielectrically isolated multiplexers, and meet all specifications of their non-hardened equivalents after total dose exposures of 100k and 200k rad(Si ...

Radiation Hardening, Reliability and Redundancy

2018
There 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, 1999
Abstract 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 ...

VLSI Processing, Radiation, and Hardening

IEEE Transactions on Nuclear Science, 1978
Process-induced radiation damage to silicon dioxide films is expected to be commonplace for VLSI circuit fabrication. This might be expected to be most serious for the production of radiation-hardened VLSI. In this paper, the oxide damage due to ion processing is reviewed and the radiation levels associated with advanced lithographic techniques are ...
