"High Spatial Resolution Radiation Detection Using Distributed Fiber Sensing Technique" by Mohamed A. S. Zaghloul, Aidong Yan, Rongzhang Chen, Ming-Jun Li, Robert Flammang, Michael Heibel, and Kevin P. Chen This paper studies perspectives on using optical fibers and distributed fiber sensing schemes to perform realtime-distributed gamma-ray radiation sensing with high spatial resolution. The radiation-induced optical property changes of aluminum-doped fibers were studied using cobalt-60 sources. The distributed optical loss of the aluminum-doped fiber was characterized using the Rayleigh backscattering optical frequency domain reflectometry (Rayleigh OFDR). The optical loss of unprotected fiber under various gamma dose rates remains linear up to 100 grays (Gy). Using the gamma radiation-sensitive fiber, the localized optical loss measured by the Rayleigh OFDR was used to map the accumulated gamma radiation dosage on the entire surface of the cylinder with a 1-cm spatial resolution. Using electrical cables as a ubiquitous sensor platforms for fiber sensor deployment, this paper explores the potential for multifunctional distributed fiber sensor by integrating distributed fiber temperature and gamma ionizing radiation sensors in electrical cables for multifunctional measurements to improve the safety of nuclear power systems at both the component and system levels. As sensors that can readily be embedded in a wide variety of materials and structures, radiation-sensitive fibers can be low-cost and highly flexible tool to gauge the performance degradation and longevity of materials and components used in the nuclear power systems. more...

"Development of Low β Single-Spoke Resonators for the Front End of the Proton Improvement Plan II at Fermilab" by Mohamed H. Awida, Donato Passarelli, Paolo Berrutti, Ivan Gonin, Sergei Kazakov, Timergali Khabiboulline, Jeremiah Holzabauer, Thomas Nicol, Joseph Ozelis, Mattia Parise, Yuriy Pischalnikov, Oleg Pronitchev, Leonardo Ristori, Gennady Romanov, Allan Rowe, Warren Schappert, Dmitri Sergatskov, Nikolay Solyak, Alexander Sukanov, and Vyacheslav P. Yakovlev A total of ten jacketed single-spoke resonators type 1 (SSR1) have been fabricated for Fermilab' injection experiment (PIP2IT). PIP2IT is a test bed for Fermilab's future accelerator named proton improvement plan II that is currently under development. SSR1 cavities operate at 325 MHz to accelerate a proton beam at a relative (to speed of light) velocity (β = 0.22). In this paper, we present Fermilab's experience in developing those spoke resonators starting from the design and analysis phase, to fabrication and extensive testing to qualify cavities for cryomodule assembly. more...
