Radiation monitor based on wavelength-dependent optical absorption in fused silica optical fibers

Title: Radiation monitor based on wavelength-dependent optical absorption in fused silica optical fibers

Abstract

A radiation monitor apparatus and method based on wavelength-dependent optical absorption in fused silica optical fibers. The radiation monitor uses the radiation induced optical changes in fused silica optical fibers as a way to quantify and differentiate the large doses of radiation from high energy photons and neutrons as well as providing a method to extend the sensitivity over a large dynamic range of doses from 103 to beyond 106 rads. The radiation monitor enables dynamic monitoring of highly ionizing radiation environments. The radiation monitor reduces sensitivity saturation at high dose levels, provides increased sensitivity over a large dynamic range of doses, and enables differentiation between high energy photon and neutron contributions or poor signal to noise.

System and method for laser-based, non-evaporative repair of damage sites in the surfaces of fused silica optics

Patent Adams, John J.; Bolourchi, Masoud; Bude, Jeffrey D.; ...

The present disclosure relates to a system for repairing a damage site on a surface of an optical material. The system may have an Infrared (IR) laser which generates a laser beam having a predetermined wavelength, with a predetermined beam power, and such that the laser beam is focused to a predetermined full width ("F/W") 1/e.sup.2 diameter spot on the damage site. The IR laser may be controlled to maintain the focused IR laser beam on the damage site for a predetermined exposure period corresponding to a predetermined acceptable level of downstream intensification. The laser beam may heat the damagemore »« less

Radiation detector based on a matrix of crossed wavelength-shifting fibers

Patent Kross, Brian J.; Weisenberger, Andrew; Zorn, Carl; ...

A radiation detection system comprising a detection grid of wavelength shifting fibers with a volume of scintillating material at the intersecting points of the fibers. Light detectors, preferably Silicon Photomultipliers, are positioned at the ends of the fibers. The position of radiation is determined from data obtained from the detection grid. The system is easily scalable, customizable, and also suitable for use in soil and underground applications. An alternate embodiment employs a fiber grid sheet or layer which is comprised of multiple fibers secured to one another within the same plane. This embodiment further includes shielding in order to preventmore »« less

Reduction of damage initiation density in fused silica optics via UV laser conditioning

Patent Peterson, John E.; Maricle, Stephen M.; Brusasco, Raymond M.; ...

The present invention provides a method for reducing the density of sites on the surface of fused silica optics that are prone to the initiation of laser-induced damage, resulting in optics which have far fewer catastrophic defects and are better capable of resisting optical deterioration upon exposure for a long period of time to a high-power laser beam having a wavelength of about 360 nm or less. The initiation of laser-induced damage is reduced by conditioning the optic at low fluences below levels that normally lead to catastrophic growth of damage. When the optic is then irradiated at its highmore »« less
