A Powerful Röntgen Ray Tube with a Pure Electron Discharge. - [""THE SINGLE MOST IMPORTANT EVENT IN THE PROGRESS OF RADIOLOGY""]
Lancaster, PA and Ithaca, NY, The American Physical Society, 1913. 8vo. In the original printed wrappers. In: ""The Physical Review, Vol II, Second Series, No. 6"". With new paper back-strip and white paper label (""Alle Zeit Wach 1842"") pasted on to upper outer corner of front wrappers. Light wear to extremities, internally fine and clean. Pp. 409-430. [Entire volume: Pp. 409-536].
First appearance of Coolidge seminal paper in which he laid the foundation for all modern the basis for all modern X-ray tubes. The Coolidge tube, which also utilized a tungsten filament, was a major development in the then-nascent medical specialty of radiology and is widely regarded as being the single most important event in the progress of radiology. “While many clever designs were implemented to compensate for the technical limitations of early X-ray tubes, the true milestone--what some experts call ‘the single most important event in the progress of radiology’--did not occur until nearly 20 years later [after Röntgen’s discovery of the X-ray]. In 1913, William Coolidge, working in the General Electric Research Laboratory, developed the first so-called ‘hot’ X-ray tube, subsequently called the Coolidge tube. Based on his earlier research, Coolidge had figured out how to make the cathode out of the metal tungsten, which has the highest melting point of all metals. With a cathode made primarily of tungsten, cathode rays could be generated by running an electric current through the cathode and heating it" the more the cathode was heated, the more cathode rays it emitted. Thus, with cathode rays generated by heat rather than gas molecule collisions, the Coolidge tube could operate in a perfect vacuum. “By the mid-1920s, the Coolidge tube had essentially replaced the old gas-filled tubes. In addition, Coolidge later designed other innovations so that higher voltages could be used to produce higher frequency X-rays. This led to the development of so-called ‘deep therapy,’ in which X-rays are used to treat deeper tissues without excessively damaging outer layers of skin. Thanks to Coolidge’s milestone redesign of the X-ray tube, the use of X-rays in medicine--for both diagnostic and therapeutic applications--expanded widely throughout the world from the 1920s ad onward. Today, Coolidge’s ‘hot’ tube design is still the basis for all modern X-ray tubes” (Jon Queijo, Breakthrough! How the 10 Greatest Discoveries in Medicine Saved Millions and Changed Our View of the World).

First publication of Pierce's seminal and exceedingly influential paper on traveling-wave tube amplifiers. A Traveling-wave tube is an electronic device used to amplify radio frequency signals to high power. Even though the invention is widely contributed to Rudolf Kompfner in 1942-43, and Nils Lindenblad patented a device in 1940 similar to the traveling wave tube, is it Pierce that invented a fully functional and useable device.""It was Pierce who exploited its [the Traveling-Wave Tube] great potential as a broadband ultrahigh frequency and microwave amplifier. Pierce's initial successes with the new amplifier and his theoretical analysis of the operation of the traveling wave principle provided stimulus for colleagues at Bell Labs and workers elsewhere to enter this field of research."" (Millman, S. A History of Engineering & Science in the Bell System, 1984, p. 177).The first communication satellite the Telstar had not been able to send signals back to earth without Pierce' Traveling-Wave Tube. The issue also contains:1. Rice, S. O. Communication in the Presence of Noice - Probability of Error for Two Encoding Schemes. Pp. 60-93.2. Darlington, Sidney. Realization of a Constant Phase Difference. Pp. 94-104.3. Eggleston, Richard C.. Conversion of Concentrated Loads on Wood Crossarms to Loads Distributed at Each Pin Position. Pp. 105-116.4.
