Description: In the early 1980s Bracewell and Kent M. Price developed a method for forming parabolic reflectors up to a few meters in diameter from flat sheets without use of a mold or template. The process involved clamping two pieces of sheet metal between two…

Description: Bracewell was on sabbatical at CSIRO for the fall 1982 semester. Material in this unit is dated 1982-1983 and includes memos, correspondence, AT Memoranda written by Bracewell, a lab notebook, and a copy of Richard X. McGee's 15-page document, "Some…

Description: Associates for Research in Astronomy included University of California, Berkeley, California Institute of Technology, and Stanford University, and was formed to collaborate on joint construction of a large antenna. The antenna was never built. This…

Description: The Stanford Radio Astronomy Observatory, historically known as "Heliopolis," was located at Stanford Field Site 515, and included the 32-antenna solar cross and the 5-element array. In 2004 Stanford University decided to demolish the antennas, which…

Description: The second major instrument developed at Heliopolis was a five-element array for galactic and extragalactic astronomy. It consisted of five 60 foot diameter antennas made to Bracewell’s design at the Heliopolis site. The antennas were configured as…

Description: The NRAO Archives has kept a representative sample of data formats from the Spectroheliograph, including punched paper tapes, punched cards, chart recordings, a 9-track tape, plots, and several forms of computer-generated maps. Stanford Daily Maps of…

Description: The first instrument developed at Heliopolis was a crossed grating array for solar observations, known also as the solar cross. The solar cross consisted of 32 parabolic antennas 10 feet in diameter arranged in two linear arrays and operated at 9.1…
