T H E NEW General Electric XRD-3 is the first complete diffraction unit. Here's what you can do with the basic XRD-3 and its components: (1) Measure diffracted intensities directly. (2) Measure fluorescent x-ray spectra directly. (3) Make use of all film technics. ALL XRD cameras and many others fit the standard diffraction instrument support. Other cameras adapt simply to the clear, flat console top. The XRD-3 is economical. There's no waste when you invest in the XRD-3. You get it as you want it. Start with the XRD-3F for film technics. And the SPG X-Ray Detector and SPG Spectrogoniometer as you need direct measurement technics. The XRD-3 is accurate. X-ray intensity is constant to plus or minus 1/à%. An electronic voltage regulator keeps primary voltage at 0.2% of output voltage. An x-ray tube current

stabilizer checks tube current drift to 0.02% variation. The exposure timer is correct to within 60 seconds in a 20-hour range. Latched ma and high voltage positions reproduce settings accurately for long series of experiments. The XRD-3 is efficient. X-ray intensity is high; the full-wave rectified transformer is rated at 50 kvp, 50 ma, with plenty of safety factor. The CA-7 tube and Geiger Counter tube are equipped with beryllium windows. A built-in water cooler saves cost of plumbing, assures long, efficient tube life. You work efficiently, too, at the desk-type console with meters, controls and indicators within easy reach. FREE—The full facts are available on the first complete diffraction analysis unit—the XRD-3. Write General Electric X-Ray Corporation, Dept. 1-6, 4855 Electric Avenue, Milwaukee 14, Wise.
