ERE'S important news for present and prospective users of x-ray diffraction. This fast, accurate method for t h e non destructive analysis of a wide range of ma terials has been advanced in effectiveness by t w o n e w accessories for t h e General Electric X R D - 3 . They a r e : (1)
Available with a wide range of accessories, t h e General Electric XRD-3 is a highly versatile tool for x-ray diffraction.

T I O N A L C O U N T E R T U B E has m u c h h i g h e r
absorption efficiency than t h e argon-filled tube. W h a t ' s more, it has n o noticeable thermal sensitivity. A n d tube failure d u e
to very high intensities a n d unnecessarily h i g h voltages is practically eliminated. Both accessories, acting together, per form linearly over five times t h e range of argon-filled multi-chamber Geiger tubes, and about 20 times t h e range of linearity of typical single-chamber G e i g e r t u b e s . T h e n e w counter assembly has less than one micro-second resolution time. T h e g r e a t r e d u c t i o n of error in t h e h i g h e r frequencies is t h e biggest, but only one, of t h e benefits of this n e w General Electric development. Y o u r G-E x-ray rep resentative will be glad to p o i n t out others. Call h i m today, or write X-Ray D e p a r t ment, General Electric Company, Milwau kee 1, Wisconsin, for P u b . U U 8 4 .
