PHOENIX TORQUE

X-Ray Diffractometer

A new driving force in X-Ray Diffraction

The specificity of the direct drive motors makes the new Phoenix goniometer unique in its gender, providing an extreme accuracy in positioning it and avoiding any use of additional mechanical device as well.

The axial motion of the new Phoenix goniometer is ensured by the direct-drive motors which are being controlled by encoders, allowing to achieve an angular resolution of about 0.00001[deg] and a direct coupling between motors and load, without any use of transmission device like straps or gears mostly affected by inertial concerns, elasticity and frequent mechanical failures.

Direct Drive Torque Motors

• High efficiency
• Low noise
• Longer lifetime
• High torque at low rpm
• Faster and accurate positioning
• Drive Stiffness

Highly reduced vibrations improve the precision of the goniometer motions; through the encoders the position of each motor can to be simultaneously controlled by means of a steady comparison between the command and the returned signals in order to immediately carry out any eventual readjustment.

Powder analysis

X-Ray Diffraction (XRD) provides any additional information beyond basic identification. If the sample is a mixture, XRD data are to be analyzed to define the proportion of the different phases contained. Further information should include the degree of crystallinity of the phase(s) contained and the deviations of the sample from their ideal composition.

• Qualitative Phase identification
• Peak position and structure determination
• Phase quanti?cation
• Phase transition
• Crystallinity
