Ellipsoidal Monochromatic X-Ray Source
The ellipsoidal monochromator FOCUS 500/600 operates according to Bragg´s Law of X-ray diffraction. A single wavelength of X-rays is reflected from a quartz single crystal mirror at a specific angle of reflection. The FOCUS 500/600 utilizes an ellipsoidal X-ray mirror. The mirror is composed of a monolithic backing support with precisely oriented atomic bonded crystal plates. High X-ray energy dispersion is achieved utilizing the mirror with a 500 mm Rowland circle diameter for FOCUS 500, and 600 mm diameter for FOCUS 600 model, used in larger chambers. The large surface area of the quartz crystals leads to an intense X-ray flux from the monochromator for high efficiency. A manipulator with precision temperature compensated drives provides three degreesof motion (two directions of tilt and one of translation, completely decoupled from each other) for accurate mirror positioning. A moveable aluminized polymer window(shutter) is provided on the Monochromator housing for differential pumping or to shield the crystal assembly during sputtering. The monochromator can be used to perform Bremsstrahlung Isochromat Spectroscopy (BIS) with a retrofittable attachment to the standard equipment.
