Measuring and Managing Electron Dose


Figure 5: STEM images of Au nanoparticles produced in a liquid cell due to electron interactions with HAuCl3


Conclusion The AXON Dose platform provides a state-of-the-art


solution for calibrating, monitoring, and tracking both the electron fluence and the total dose delivered to specific areas of the sample on a pixel-by-pixel basis. This ability unlocks a new paradigm for imaging dose-sensitive samples and understanding the electron beam interactions that can affect the rigor and reproducibility of in situ and operando TEM experiments.
