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.
