minus % per cent. Resolution of diffraction data is optimum— for powder data, 0.02 degree maximum. Kou o r e c o m p i e t e l y e q u i p p e d . There are available for use with the basic XRD-3 components which make possible (1) the direct measurement of diffracted intensities, (2) the direct measurement of fluorescent x-ray spectra, (3) all film technics. All XRD cameras and many others fit the standard diffraction instrument support. T h e clear flat top around and under t h e tube makes the adaption of other cameras simple. Kou are seated. You work at a desk-type console. All meters and controls are within easy reach. You read spectrogoniometer angles from stationary indicators without your leaving your chair. Controls, transformer and water cooler are within the console.

Kou a r e s u r e . You get C-E accuracy in the XRD-3. Latched ma and high-voltage positions reproduce settings accurately for long series of experiments. Exposure timer is correct to within 60 seconds in a twenty-hour range. X-ray intensity is constant; plus or
