Study of Solid-State and Traveling-Wave Maser Techniques
Abstract
This program called for the development of an ultra low noise broadband traveling wave Maser. This MASER had four separate electronic devices incorporated into the overall package; the TWM superconducting solid state limiters, superconducting solenoid and a superconducting RF pump source. A TWM was designed which had an inherent bandwidth of 300 MHz and a noise temperature of less than 9 degrees K. A low level power limiter using the mechanism of impact ionization in bulk germanium was demonstrated. The magnetic field for the TWM was provided by a superconducting solenoid that can be switched into a persistent mode of operation. Theoretical studies were conducted to determine the feasibility of the use of superconducting tunnel junctions as an RF pump source for the MASER. Present state-of-the-art techniques were not considered adequate for accomplishment of the desired design parameters. Conventional klystrons were therefore provided for the pumping circuitry.
