Raman measurements were carried out to probe the spectroscopic signatures of the ion beam irradiation-induced damage and their in-depth profiles on a Uranium dioxide sample previously cut and polished prior to performing a 25 MeV He2+ cyclotron beam irradiation. Raman spectra clearly show the creation of three defects bands (U1 ≈ 530, U2 ≈ 575, and U3 ≈ 635 cm−1) resulting from the ion irradiation and also some changes in the T2g peak of UO2. Their in-depth distribution inside the sample exhibits a clear increase of the damage from the surface up to the position of the implanted He.

The in situ Raman probing of a UO2 ceramic in [Ar/H2, 95/5] gas atmosphere followed by exposure to He2+ ionic irradiation coming from a cyclotron accelerator was implemented. It was observed that the growth of Raman defect bands exhibits a unique kinetic nicely modelized by a simple direct impact model, and with an annealing rate constant of 5.6 × 10−4 ± 4 × 10−5 s−1 for an ionic flow of 50 nA and an ions-beam induced sample heating of 170 ± 10 °C. Also, it was observed that the Ar plasma induced by the ions-beam is a sensitive probe of the presence of the ions-beam.
About Me
Aurélien Canizarès is an engineer specializing in the development of optical spectroscopy instruments at CNRS in Orléans, France, since December 2003. His work includes the development of a portable Raman spectrometer for in situ diagnostics tailored for studying materials for nuclear applications, as well as the development and maintenance of a range of Raman, Infrared, and Brillouin spectrometers. He conducted research on the in situ study of structural relaxations in silica using vibrational spectroscopy. Aurélien Canizares obtained his PhD in Physics from the University of Orléans in 2011 and holds a degree in Physical Optics Engineering that he earned from Polytech' Orléans in 2002.
