The improved efficiency of the new G-E krypton-filled proportional counter tube and amplifier is quickly apparent, even when recorded on semi-log paper.

Two new accessories extend accuracy of General Electric XRD-3 diffraction units Τ TERE'S important news for present and -*- -*• prospective users of x-ray diffraction. This fast, accurate method for the non­ destructive analysis of a wide range of ma­ terials has been advanced in effectiveness by two new accessories for the General Electric XRD-3. They are: (1) N E W P R O P O R T I O N A L

Available with a wide range of accessories, the General Electric XRD-3 is a highly versatile tool for x-ray diffraction.

COUNTER

A M P L I F I E R that converts present G-E Geiger tube to proportional counter opera­ tion. Connection to your present XRD-3 is extremely simple. (2) N E W KRYPTON-FILLED PROPOR­ TIONAL COUNTER T U B E has much higher

absorption efficiency than the argon-filled tube. What's more, it has no noticeable thermal sensitivity. And tube failure due

to very high intensities and unnecessarily high voltages is practically eliminated. Both accessories, acting together, per­ form linearly over five times the range of argon-filled multi-chamber Geiger tubes, and about 20 times the range of linearity of typical single-chamber Geiger tubes. The new counter assembly has less than one micro-second resolution time. The great reduction of error in the higher frequencies is the biggest, but only one, of the benefits of this new General Electric development. Your G-E x-ray rep­ resentative will be glad to point out others. Call him today, or write X-Ray Depart­ ment, General Electric Company, Milwau­ kee 1, Wisconsin, for Pub. UU124.
