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 an overall maser system. The specific areas of interest of this program are: (1) braod instantaneous maser bandwidth (500 Mc); (2) incorporation of solid-state power limiters to protect the maser from saturating; (3) use of superconducting solenoids to provide the magnetic field for the maser; and (4) investigation of the possibility of using the superconducting tunneling effect to provide the RF pump power to the maser. A theoretical analysis of the broad-band travelingwave masers was made, and several successful experiments were performed. General expressions that show the important parameters affecting the broadbanding are given, and practical requirements for the structure and magnetic field are established. An analysis of the ferrite approach to the low-level limiter problem was made and indicates some ibherent limitatons. A second approach of using superconducting techniques for limiting is suggested and is being investigated. Preliminary work on superconducting thin-film tunneling and closed-cycle refrigerators is presented. (Author)
