Silicon nitride membrane application in synchrotron radiation light source

In synchrotron radiation light sources, silicon nitride membrane are used as optical components for high-energy X-ray and ultraviolet rays. With a series of excellent characteristics, they play an important role in synchrotron radiation experiments.

Firstly, silicon nitride is a very hard material with high heat resistance and corrosion resistance. This means that it can withstand high-temperature and high pressure environments while also resisting the corrosion of chemical substances. Therefore, silicon nitride membrane are one of the most commonly used components in synchrotron radiation experiments.

Secondly, silicon nitride has excellent thermal conductivity, which can effectively transmit and scatter high-energy rays, making the beam in the experiment process more stable and reliable. In addition, silicon nitride has a low friction coefficient, making it smoother during movement or adjustment.

In synchrotron radiation light sources, silicon nitride membrane are usually used as beam collimators or filters. The role of the collimator is to ensure the straight propagation of the beam, while the filter can filter out unwanted wavelengths or energy levels of light. These silicon nitride membrane can effectively protect the synchrotron radiation light source from external environmental interference while also improving the optical performance of the experiment.

In addition, silicon nitride thin film windows have also been widely used in synchrotron radiation light sources for scanning transmission soft X-ray microscopy imaging technology (STXM) experiments. In these experiments, silicon nitride thin films serve as support membranes for biological samples, protecting them from external environmental interference while also providing a stable support substrate to enable better observation and analysis of the biological samples.

In summary, the silicon nitride membrane used in synchrotron radiation light sources have the advantages of high hardness, high thermal conductivity, and a low friction coefficient. They can effectively protect synchrotron radiation light sources and experimental samples, improving the optical performance and analysis accuracy of experiments.
