Dynamic SIMS for Characterisation of Nuclear Materials (32 mins)
To guarantee the longevity of structural nuclear materials and learn about the mechanisms occuring during reactor accidents, it’s important to understand the diffusion and migration mechanisms of fission products in nuclear materials and fuel.
Various materials can be analysed with SIMS after ion implantation with natural isotopes of high fission yield species (eg molybdenum, helium, xenon, iodine). The webinar also covers dynamic SIMS characterisation of nuclear particles from nuclear facilities for safeguarding purposes.
The data presented in this webinar is a collaborations between CAMECA and several users from the nuclear science field worldwide.
Optimising Detection Limits for Light Elements (H, C, O) (25 mins)
This webinar focuses on optimising detection limits for light elements (hydrogen, carbon and oxygen atmospheric species) in silicon-based materials using dynamic SIMS.
Data about H, C and O low-level impurities introduced during processing and/or ageing is important for understanding semiconductor device lifetime and failure. Dynamic SIMS is useful for evaluating the concentration of impurities in solids, because of its high sensitivity and depth profiling capabilities.
The webinar explains how detection limits can be improved using a pre-sputtering method. Results include data acquired using multiple sample holders and an automated storage chamber.
