Study on effects of swift heavy ion irradiation in CeO2 using XRD method
نویسندگان
چکیده
In our previous study, we have used CeO2 as a simulation material of a fission fuel, UO2, because CeO2 has many properties that are similar to UO2. We reported the effects of swift heavy ion irradiation (mainly 200 MeV Xe ions) in CeO2 to simulate radiation effects of high energy fission products in UO2 [1,2]. To study radiation effects at higher energies and with heavier ions additional irradiation experiments were performed with 1.7 GeV Au ions. Beam-induced structural modifications were analysed by means of X-ray diffraction (XRD).

Optical waveguides having some unique characteritics can be fabricated in Lithium niobate using high energy heavy ions. High optical confinement or very thick optical waveguides can be obtained using moderate (10 cm) or even ultralow (10 cm) fluences. The method has also been applied to other crystals of photonic interest. We present a review of the recent achievements obtained. Lithium niobate...
