Editing X-ray microscope (section)

==Scanning transmission==
Sources of soft X-rays suitable for microscopy, such as [[synchrotron]] radiation sources, have fairly low brightness of the required wavelengths, so an alternative method of image formation is scanning transmission soft X-ray microscopy. Here the X-rays are focused to a point, and the sample is mechanically scanned through the produced focal spot. At each point the transmitted X-rays are recorded using a detector such as a [[proportional counter]] or an [[avalanche photodiode]]. This type of ''scanning transmission X-ray microscope'' (STXM) was first developed by researchers at Stony Brook University and was employed at the [[National Synchrotron Light Source]] at [[Brookhaven National Laboratory]].
