Rotating Anode for X-ray Diffraction.

This article features the high-power rotating anode x-ray source of dual-port design from Nicolet Analytical Instruments. This product provides 18 kilowatt of continuous power for high-flux diffraction experiments. Standard operation gives the user dual-port capability with either two-vertical-line or two-spot focusing diffractometers. The system can also be configured for high-brilliance operation with a cathode assembly 0.1 X 1 millimeter in size. The rotating anode has a microprocessor controller to monitor system status and regulate operation of the generator. The system is compatible with Nicolet horizontal 2-, 3- and 4-circle goniometers, and it accomodates Nicolet's tuneable x-ray mirrors for use in microdiffraction experiments, For experiments on rapidly decaying crystals, the rotating anode can be used with a Nicolet area detector, providing what Nicolet describes as the fastest commercially available factory-integrated system for collecting x-ray diffraction data. Horizontal goniometers equipped with position-sensitive detectors can also be employed for high speed polycrystalline data collection.
