Description:Shing Kuo Pan and Neil Horner in Charlottesville's Central Development Laboratory in August 1983, testing a Superconductor-Insulator-Superconductor (SIS) millimeter-wave mixer for the Tucson 12-m telescope. They are in front of the mixer test setup checking the I-V (current-voltage) curve of the SIS mixer on the oscilloscope. At the low-left corner is the square aluminum mixer test dewar. The mixer dewar is cooled by a 4K closed-cycle, JT/1020 refrigerator. On one side of the dewar, above the green tray at the low-left corner, is the dewar vacuum window (white, circular). On the other side (facing toward Pan and Horner) are three bias/monitor ports. [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.
