Book excerpt: Samples representative of most of the optical fibers presently available in lengths of 10 m or more were tested for their responses to energetic radiation. Glass fibers doped with three different levels of cesium were also prepared and tested. Permanent and transient x-radiation effects tests were performed. Neutron effects tests were performed. All of the fibers tested showed decreases in transmission when exposed to radiation. All of the fibers emitted fluorescent light pulses when exposed to intense x-ray pulses.

Available in PDF, EPUB and Kindle. Book excerpt: The chapter continues previous reviews on radiation effects in optical fibers and on the use of optical fibers/optical fiber sensors in radiation monitoring, published by InTech in 2010 and 2012, by referring to radiation effects in optical materials, with an emphasis on those operating from visible to mid-IR, and on some photonic devices such as optical fibers for amplifiers, fiber Bragg gratings and long period gratings. The focus is on optical materials and fiber-based devices designed for both terrestrial and spaceborne applications. For the presented subjects, an overview of available data on X-rays or gamma rays, electron beams, alpha particles, neutrons, and protons effects is provided. In addition, comments on dose rate, dose, and/or temperature effects on materials and devices degradation under irradiation are mentioned, where appropriate. The optical materials and photonic devices reliability under ionizing radiation exposure is discussed as well, as the opportunities to use them in developing radiation sensors or dosimeters. The chapter includes an extensive bibliography and references to last published results in the field. Novel proposed applications of photonic devices in charged particle beam diagnostics, quasi-distributed radiation field mapping and the evaluation of radiation effects in materials for mid-IR spectroscopy are briefly introduced to the reader.

Available in PDF, EPUB and Kindle. Book excerpt: The results of an extensive investigation of the optical response of thirteen common optical materials to 2.5-MeV electron irradiation is reported. Radiation-induced absorption and absolute radioluminescence yields were measured in the wavelength range 0.14 to 0.9 micrometers for dose rates between 0.05 to 0.00005 rad/sec at doses from 0.0023 to 0.00000045 rads. Sapphire, fused and crystalline quartz and ten Schott optical glasses were investigated. Determinations were made of (a) the absolute radioluminescence yield, (b) the dose rate dependence yield (c) the spectral and temporal distribution of the radioluminescence and induced absorption, (d) the growth curve of the induced absorption versus total dose, (e) the dose-rate dependence of the absorption, and (f) the bleaching of the absorption after irradiation. In addition, where available, samples from different melts were investigated to determine the variation in the above effects with manufacturing variation.
Download or read book Radiation Effects in Materials written by Waldemar Alfredo Monteiro and published by BoD – Books on Demand. This book was released on 2016-07-20 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of radiation effects has developed as a major field of materials science from the beginning, approximately 70 years ago. Its rapid development has been driven by two strong influences. The properties of the crystal defects and the materials containing them may then be studied. The types of radiation that can alter structural materials consist of neutrons, ions, electrons, gamma rays or other electromagnetic waves with different wavelengths. All of these forms of radiation have the capability to displace atoms/molecules from their lattice sites, which is the fundamental process that drives the changes in all materials. The effect of irradiation on materials is fixed in the initial event in which an energetic projectile strikes a target. The book is distributed in four sections: Ionic Materials; Biomaterials; Polymeric Materials and Metallic Materials.

Download or read book Effect of Simulated Space Radiation on Selected Optical Materials written by C. A. Nicoletta and published by . This book was released on 1972 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of simulated Nimbus spacecraft orbital (1100 km, circular, and polar) radiation on wide bandpass glass filters, narrow bandpass thin film interference filters, and several fused silicas was determined by transmittance measurements over the 200 to 3400 nanom wavelength region. No changes were observed in the filters, which were shielded with fused silica during irradiation, after exposure to a 1-year equivalent orbital dose of electrons, nor in the fused silicas after the same electron exposure plus a 1-year equivalent dose of protons. Exposure to a 1/2-year equivalent dose of solar ultraviolet radiation caused a significant degradation in the transmittance of two ultraviolet-transmitting interference filters but had no effect on two colored glass filters that transmitted in the visible and near infrared regions. As a result of the ultraviolet exposure the fused silicas exhibited losses of several percent over the 200- to 300 nanom wavelength region.

Available in PDF, EPUB and Kindle. Book excerpt: Department of Energy and Defense Programs systems are becoming increasingly reliant on the use of optical technologies that must perform under a range of ionizing radiation environments. In particular, the radiation response of materials under consideration for applications in direct optical initiation (D.O.I.) schemes must be well characterized. In this report, transient radiation effects observed in a KD*P crystal are characterized. Under gamma exposure with 2 MeV photons in a 20--30 nsec pulse, the authors observe induced absorption at 1.06[micro]m that causes a peak decrease in overall sample transmittance of only 10%. This induced loss is seen to recover fully within the first 30[micro]sec.

This book was released on 1973 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: An aspect of radiation effects that is rapidly becoming one of the most critical areas of concern, particularly with regard to military satellites, is the problem of radiation-induced noise in electrooptical systems. An important aspect of such noise is the radiation-induced luminescence in optical materials. This memorandum describes an empirical model used to interpret the phenomena of radiation-induced luminescence and coloration and reports on some of the significant experimental observations in support of the model. Experimental work directly related to that providing the basis for this study has been performed by the author in the Grumman Research Department as part of the Air Force funded SAS-II study. The kinetic analysis presented as based on the model emphasizes the limiting behavior of induced luminescence in the low radiation intensity region. (Author).

Book excerpt: Department of Energy and Defense Programs systems are becoming increasingly reliant on the use of optical technologies that must perform under a range of ionizing radiation environments. In particular, the radiation response of materials under consideration for applications in direct optical initiation (D.O.I.) schemes must be well characterized. In this report, transient radiation effects observed in Schott filter glass S-7010 are characterized. Under gamma exposure with 2 MeV photons in a 20--30 nsec pulse, the authors observe strong initial induced fluorescence in the red region of the spectrum followed by significant induced absorption over the same spectral region. Peak induced absorption coefficients of 0.113 cm−1 and 0.088 cm−1 were calculated at 800 nm and 660 nm respectively.
