Y New HRA electron tube "freezes"movements that occur, and are ended, in millionths of a second I Now scientists at RCA Labora tories work with slivers of time too infinitesimal for most of us to imagine. Their new electron tube, the Graphechon, makes it possible. For instance, in atomic re search, a burst of nuclear energy may flare up and vanish in a hundred-millionth of a second. The Graphechon tube oscillo graph takes the pattern from an electronic circuit, and recreates it in an image which can last for a minute and a half. Scientists may then observe the pattern of the burst . . . measure its energy and duration. With Graphechon we can now watch fleeting phenomena which occur at ran dom, outside our control. It is not only applied to nuclear research, but also to studies of electrical current .. . or in new uses of radar and television. Like so many products of RCA research, Graphechon widens man's horizons. See the latest wonders of radio, tele vision, and electronics in action at RCA Exhibition Hall, 36 West 49th St., N. Y.

Progressive research, like that which gave us the Graphechon tube, accounts for the superiority of RCA Victor's new 1950 home television receivers.
