Caltech SIS Receivers
Abstract
This paper describes the superconductor-insulator-superconductor (SIS) receivers which are being used in the Owens Valley Radio Observatory Millimeter Interferometer. These receivers operate over the frequency range from 85 to 115 GHz using a simple circular waveguide mixer block design and have achieved double sideband noise temperatures as low as 70 K. They have been in use since 1981 and have proven to be reliable and easy to operate.
Additional Information
The successful operation of the SIS receivers used in the millimeter interferometer has required the efforts of many people. I would particularly like to acknowledge the work of R. E. Miller of AT and T Bell Labs in providing the SIS tunnel Junctions, M. J. Wengler for his theoretical calculations and performance measurements. and C. L. Spencer for his effort in constructing and maintaining the receivers and their cryogenic systems.Attached Files
