🤔 Have you ever wondered why scientists use X-rays in their research? Just as X-rays employed in hospitals enable the visualization of bones within our bodies, scientists employ X-rays to gain insights into the inner workings of materials, uncovering their molecular structures and properties in great detail. To accomplish this, they use a specialized instrument known as an X-ray free electron laser, or XFEL for short. XFELs generate extremely powerful and focused X-ray beams with such brightnes
