Congratulations to Aysha Al Neyadi, Associate Researcher at DERC, for winning the Young Scientists Competition at the 14th International Conference Interaction of Radiation with Solids that ran from 21 to 24 September at Minsk, Belarus.
Aysha co-authored the paper, titled 'The Structure and Phase Composition Stability of Amorphous Zirconium Irradiated with Helium Ions,' with her supervisors from Belarus State University, Dr. V. V. Uglov and Dr. S. V. Zlotski, as well as Dr. A. Bouchalkha and Dr. N. Mora, from Technology Innovation Institute. The paper was part of the framework of her master's program in high current electronics at Belarusian State University in Minsk.
The paper discussed amorphous alloy samples based on irconium with different metals that were irradiated using Helium ions at operating energy of 40 keV under room temperature conditions with dosage from 5'1017 to 7'1017 cm-2. The phase analysis of the samples was conducted using an X-ray diffractometer (Rigaku). XRD analysis revealed amorphous and crystalline formation with the structure of zirconium base foils.
The experiment aimed to find the elemental composition and amorphous structure of the alloy's influence on its radiation stability after ion irradiation. The paper collated data of samples based on Zirconium, methods of preparation, experimental setup, and the results of an experiment.
- Irradiation with helium ions does not lead to a change in the structure of the foils.
- The irradiation led to a shift in the diffraction peaks of crystalline phases to the region of smaller angles for all crystalline and crystalline amorphous foils.
- Lastly, it led to a decrease in the angular position of the amorphous halo.
Commenting on the award, Aysha said: “I am proud of my contributions and the international recognition that TII has received as a result of my hard work and dedication. I aim to continue my contributions to the research and development community in an effort to shape an advanced technology ecosystem through important scientific collaborations with our academic partners.”
