STUDY OF SOLID-STATE AND TRAVELING-WAVE MASER TECHNIQUES.
Abstract
The purpose of this program is to develop improved maser techniques and apply them to a broad-band maser system. Magnetic shimming techniques capable of providing the proper field gradients in a superconducting solenoid have been successfully tested. The analysis of broad-banding was extended to include the effects of nonideal magnetic field gradients and RF field distributions in the TWM structure. Correlation between theory and experiment is now much improved, facilitating the evaluation and application of these techniques to a deliverable breadboard. Limiting characteristics in a broad-band stripline semi-conductor limiter at 4.2K have been obtained. Techniques to decrease the limiting by using a more resonant, ridged waveguide structure are being developed. An analysis of a fine-wire super-conducting limiter indicates that the operating bandwidth of such a device would be too narrow for the intended application. An analysis of the feasibility of superconducting thinfilm tunneling techniques as a pump source for masers has been completed and is presented. The obtainable power levels appear to be insufficient for maser pumping. Other solid-state techniques are being evaluated. (Author)
