Insulin derivative measurements on a laboratory powder diffractometer

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...

Diffractometer-Control Software For Bragg-Rod Measurements

We present Generalized Diffractometer Control (GDC), a diffractometer-control software package developed specifically for high-precision measurements of Bragg rods; we discuss its features and analyze its performance in data collection. GDC, implemented at several APS beamlines, controls a six-circle diffractometer in either Eulerian or kappa geometry, yet does not assume a mechanically ideal d...

Measuring 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...
