Remote Measurement of Uranium Hexafluoride VIA Fiber Optics

Open Access Open Access

Abstract

An extrinsic-type fiber sensor is discussed where a high-peak-power laser beam is conveyed into a gas centrifuge, and a fluorescence signal thus produced is returned by a fiber bundle. This is an example of a fiber sensor application which requires the maximum possible laser peak power to be delivered to the remote location. The purpose of the present application is to measure the pressure and temperature inside an operating gas centrifuge which is used to enrich uranium hexafluoride. A longer-term goal of this work is to measure velocity profiles in this environment by a laser-induced breakdown/ion time-of-flight method.
