Identification number: LZP-2023/1-0453
Type: Latvian Council of Science Fundamental and Applied Research project
Project duration: 01.01.2024.-31.12.2026.
Project Leader: Dr.phys. Anatoli Popov, Institute of Solid State Physics, University of Latvia
Total funding: 300 000 EUR
Project aim:
The main goal of this project is detailed characterization and estimation/prediction of radiation tolerance of some advanced optical and scintillator materials, functioning under prolonged radiation environment.
Project description:
The task of this project is to establish the relationship between radiation-induced structural defects, and the doses of incident radiation of different types (ions, neutrons, gamma rays, protons) in optical and scintillating materials currently used/in priority list for Space, HEP, neutron research and medical imaging application. The effect of radiation defects on the optical properties of selected functional materials will be simulated.
Expected scientific results:
- The changes of diffusion defect parameters (activation energy) will be evaluated for heavily irradiated materials.
- New relations of the defect migration-recombination properties and radiation fluence will be established.
- The effects of radiation on EPR spectra and luminescence spectra will be studied.
- The effects of radiation on Raman modes in heavily-irradiated materials, where optical methods fail, will be studied to find defect-induced vibrational modes.
- The effect of dopants will be studied and their energy level positions within band gap evaluated.
