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:Bob Brown watches as John Payne and Betty Stobie work on one of the 12 meter receiver packages. There were 4 receiver "bays" that accommodated receiver packages like the one shown. Usually one receiver "band" per package, i.e. the 1mm receiver band would have been housed in one of these packages. [show more]

Description: In the Central Development Laboratory in Charlottesville in 1993, NRAO engineer Nancyjane Bailey, works with the dewar used to test the superconducting SIS receivers (the so-called "rockets") for NRAO's 12 meter telescope at Kitt Peak, AZ. Nancyjane oversaw the construction of all the rockets for the 1.3, 2, and 3-mm bands on the 12 meter telescope -- 17 rockets in all including spares, a major accomplishment. One receiver used 8 of the 230 GHz (1.3-mm) rockets, and another receiver held 2 rockets for each of the three bands. At one point, there was an implosion of one of the dewar vacuum windows, which caused substantial damage to the internal copper heat shield and one of the rockets. The vacuum window was subsequently redesigned. All the SIS mixers for the 12-m telescope (and later for ALMA Bands 3 and 6) were designed in the CDL by Tony Kerr and Shing-Kuo Pan and fabricated in Arthur Lichtenberger's lab at University of Virginia.
