Description:In May 1982, in the Green Bank Warehouse where the work was done, John Payne (left) and John Findlay contemplate engineering issues during the fabrication process for the new surface and back-up structure that would convert Tucson's 36 foot telescope into a 12 meter telescope. The 36 foot closed for resurfacing and upgrade on 15 July 1982, and first observations with the 12 meter were made on 17 January 1984. [show more]

Description:In June 1974, John Payne (back to camera), Mike Balister, and Ken Kellermann consider the four frequency Cassegrain receiver and feed assembly, with optics designed by Peter Napier, that was the prototype system for the VLA and was also used for the VLBA. It was a new and innovative concept, first developed by the Jet Propulsion Laboratory for use on their Deep Space Network antennas, where the four feeds were offset from the electrical axis and could be illuminated by rotating the asymmetric subreflector. Here it is being installed for testing on the 140ft antenna in Green Bank. [show more]

Description:The surface accuracy of NRAO's 36 foot telescope in Tucson, which began operation in January 1968, fell significantly short of design specifications. In summer 1975, after measuring and mapping the surface to produce a contour map of surface errors, removing the surface paint, projecting the map onto the surface, and marking the contours on the aluminum surface, staff attempted to correct imperfections in the surface by "foiling the telescope." They filled surface "holes" with layers of 0.005 inch thick adhesive aluminum foil. Corrections were less effective than expected. Later the basic problem turned out not to be imperfections in the surface of the reflector but, rather, that the shape distorted with temperature (aluminum structure attached to a steel support structure - bimetallic strip effect) and also with gravity as the reflector tilted. Uncorrectable defects were part of the impetus for replacing the 36 foot reflector with a new 12 meter reflector. In this photo, John Payne (on the left in plaid cap), Paul Rhodes (right), and Victor Gasho (back to camera behind Paul) are hard at work attaching the adhesive foil. [show more]

Ken says he was the project scientist "assigned to hassle the Electronics Division." He adds, "Note I was comfortably sitting down and seem to be the only one that didn’t look puzzled, as appropriate for an advisor." After installation of the Cassegrain cabin on the 140 ft telescope the system was integrated and evaluated by Chuck Brockaway and Tom Dunbrack. [show more]

Description:In October 1969 during the depths of the Cold War, after more than a year of scientific, diplomatic, and bureaucratic planning (and reams of paperwork), and followed by innumerable technical and logistical problems, the first US-USSR VLBI observations were made between the NRAO's 140 Foot Telescope in Green Bank and the Lebedev Physical Institute's 22 meter radio telescope in Crimea. Teams of NRAO and Soviet observers were on site for the hands-on observations. As described by Ken Kellermann in his series of articles in The Observer, a party was planned to follow the end of observing, "but as the last hour approached the observing room began to fill with spectators. When the last tape started the Russians produced, in their usual efficient manner, a round of glasses and several bottles of Cognac, and with toasts of Soviet-American friendship and cooperation, the first Green Bank-Crimea VLBI experiment was declared a success on the basis of having analyzed less than one half of one percent of the data." Celebrating in this photo are, standing left to right, Ivan Moiseyev (Director of the Crimean radio telescope), John Payne (NRAO), Victor Efanov (telescope staff). Seated is an unnamed member of the Crimean telescope staff. [show more]
