Abstract

A new Huber Guinier Camera 670 was installed on an Ultrax 18- Rigaku X-ray rotating Cu anode source. A monochromator (B=360 mm) attached to the source providing Kα1 radiation. The camera is used for powder diffraction utilizing transmission geometry. An image plate makes the position sensitive detection measurement. This configuration enables fast scanning with high resolution.

In order to evaluate the camera quality we collected data of some classical reference materials like silicon, quartz and some standards supplied by NIST USA and organic complexes. Each sample was measured at 4kW for 1 to 2 minutes at 2θ between 0 to 100 degrees. The results were compared with previous references. It was found that the relatively high instrumental background can be easily dealt-with and do not pose difficulty in the analysis of the data.
