Vacuum-tubes
Found in 8 Collections and/or Records:
Albert Rose papers, 1926-1974
The Albert Rose papers include figures and lab notes, correspondence, and technical papers related to Rose’s work on picture tubes and photoconductivity at the David Sarnoff Research Center.
The Albert Rose photographs focus on the development and testing for television picture quality including the orthicon, super xx film, electron images, optical images, low velocity scanning electron microscope images, and direct light spot scanning. As well as electron beam paths in cylindrical negative fields and around horseshoe magnets.
Fifty-eight of Rose's lab notebooks (1935-1958) can be found in Record group 26.
Humboldt W. Leverenz papers, 1931-1953
The Humboldt Leverenz papers include reports on experiments related to cathode ray tubes, afterglow powders, phosphors, and dark trace tube screens from 1941 to 1953. Experiment reports from 1941-1945 include a stamp and security information from the Office of Scientific Research and Development. Included within the reports are graphs, diagrams, calculations, and some images from the experiments. The papers also include notes and calculations by Dr. Leverenz as well as records, manuals, and progress reports from the Chemico-Physics section of RCA Laboratories from 1943 to 1949.
Forty-three of Leverenz's lab notebooks (1931-1954) can be found in Record group 26.
James R. Matey papers, 1974-2003
James R. Matey preserved documents which help to explain his work in developing instruments used to control and manipulate data and materials, tools to measure the impact of materials introduced in his experiments, and microscopes which became useful to describe and improve various products. His work is reflected clearly by the number of patents he received, and by the many records which document his work with microscopy, picture tubes, and VideoDiscs.
The Matey papers includes photographs, overhead transparencies, 35mm slides, videocassettes, and one video disc. These depict work done with scanning capacitance microscopy (SCaM) including micrographs of silicone on sapphire, video discs, and graphs and diagrams used in a presentation on scanning capacitance microscopy.
Twenty-nine of Matey's lab notebooks (1977-1991) can be found in Record group 26.
Philip M. Heyman papers, 1980-2002
The documents in the Philip M. Heyman papers describe the development with Thomson Consumer Electronics of a picture tube named Eagle, which was intended to prevent noise from vibrations in tubes used for generating audio/visual sound and display. Scientists named the noise microphonics. In addition, the papers explain the work of Heyman and his team to develop flat screen televisions, as well as describe the complexity of flat screen TV.
Seventeen of Heyman's lab notebooks (1963-1982) can be found in Record group 26.
Products, 1912-1965
Randy E. McCoy papers, 1985-1988
The Randy E. McCoy papers consist primarily of reports, meeting minutes, and test results from the David Sarnoff Research Center's support of display tube manufacturing at RCA (later GE and Thomson) facilities in Lancaster, Marion, and Scranton.
Two of McCoy's lab notebooks (1979-1989) can be found in Record group 26.
Tubes, 1933-1976
The Tubes series is organized into two subseries: Harrison and Tubes. The Harrison materials document the facilities, equipment, and machinery of manufacturing tubes. There are some images of tubes. These images date from 1934 to 1946. The Tubes subseries is images of tubes, most tubes are identified by number type. These materials date from 1933 to 1976.
Vladimir K. Zworykin papers, 1908-1981
The collection includes Dr. Vladimir K. Zworykin's records he created shortly after joining the research division of Radio Corporation of America (RCA) in 1929 through his formal retirement in 1954 as a vice president of RCA Laboratories, and from there through his active post-retirement career. While Zworykin is best known for his work on television during the 1920s and 1930s, the larger part of the collection consists of material documenting Zworykin’s work in medical electronics research and chairmanship of the International Institute for Medical Electronics and Biological Engineering.
Zworykin’s papers are composed of his publications, lectures, and other writings; patents and awards conferred; correspondence with domestic and international colleagues related to the span of his research from television to medical technologies; and research materials.
Photographs document Zworykin's career at RCA including work on kinescopes, the electron microscope, television, and other equipment. Audio and video materials contain a documentary of Zworykin's life and interviews about Zworykin with other RCA employees.
Ten of Zworykin's patent disclosure books (1930-1943) can be found in Record group 26.
