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 کاملEchidna—the new high-resolution powder diffractometer being built at OPAL
A new powder diffractometer aiming for high angular, and thus high reciprocal space, resolution is being constructed within the Neutron Beam Instrumentation Project at the upcoming Australian Neutron Source OPAL, near Sydney. The neutron flux at the sample can be expected to be up to 10 n/cm/s. With an array of 128 position sensitive detectors, each equipped with a 30 cm high Söller collimator ...
متن کاملBuilding a high resolution total scattering powder diffractometer – upgrade of NPD at MLNSC
The neutron powder diffractometer NPD at the Manuel Lujan Neutron Scattering Center (MLNSC) at Los Alamos National Laboratory is the neutron powder diffractometer with the highest resolution in the United States. We are currently upgrading NPD by adding a large number of position-sensitive detectors in the backscattering position. The upgraded instrument will make it possible to collect data fr...
متن کاملMeasuring Single Crystal Diffuse Neutron Scattering on the Wombat High Intensity Powder Diffractometer
Single crystal diffuse scattering was collected on the Wombat high-intensity powder diffractometer at the OPAL reactor at the Bragg Institute. The difficulty in measuring diffuse scattering comes from its relatively low intensity compared to the Bragg peaks, a factor of 10−10 smaller. Wombat allows collection of diffuse scattering due to its high intensity and large two-dimensional detector. Di...
متن کاملTuning the instrument resolution using chopper and time of flight at the small-angle neutron scattering diffractometer KWS-2
Following demand from the user community regarding the possibility of improving the experimental resolution, the dedicated high-intensity/extended Q-range SANS diffractometer KWS-2 of the Jülich Centre for Neutron Science at the Heinz Maier-Leibnitz Center in Garching was equipped with a double-disc chopper with a variable opening slit window and time-of-flight (TOF) data acquisition option. Th...
