A compact high-resolution X-ray powder diffractometer
A new powder diffractometer operating in transmission mode is described. It can work as a rapid very compact instrument or as a high-resolution instrument, and the sample preparation is simplified. The incident beam optics create pure Cu Kα1 radiation, giving rise to peak widths of ∼0.1° in 2θ in compact form with a sample-to-detector minimum radius of 55 mm, reducing to peak widths of <0.05° i...
متن کاملA `beam-selection' high-resolution X-ray diffractometer
A new diffractometer that can be described as a high-intensity low-background high-resolution diffractometer for analysing perfect, nearly perfect and highly imperfect materials on a routine basis is presented. The instrumentation is very simple and uncomplicated, yet the way in which it works is less obvious. The sample requires minimal sample alignment, the resolution can be adjusted to optim...
متن کاملHigh-resolution compact X-ray microscopy.
We demonstrate compact full-field soft X-ray transmission microscopy with sub 60-nm resolution operating at lambda= 2.48 nm. The microscope is based on a 100-Hz regenerative liquid-nitrogen-jet laser-plasma source in combination with a condenser zone plate and a micro-zone plate objective for high-resolution imaging onto a 2048 x 2048 pixel CCD detector. The sample holder is mounted in a helium...
متن کاملCompact high-resolution differential interference contrast soft x-ray microscopy
We demonstrate high-resolution x-ray differential interference contrast DIC in a compact soft x-ray microscope. Phase contrast imaging is enabled by the use of a diffractive optical element objective which is matched to the coherence conditions in the microscope setup. The performance of the diffractive optical element objective is evaluated in comparison with a normal zone plate by imaging of ...
متن کاملTemperature gradient analyzers for compact high-resolution X-ray spectrometers
Compact high-resolution X-ray spectrometers with a one-dimensional temperature gradient at the analyzer crystal are considered. This gradient, combined with the use of a position-sensitive detector, makes it possible to relax the usual Rowland-circle condition, allowing increased space at the sample position for a given energy resolution or arm radius. Thus, for example, it is estimated that ap...
