SUPERCONDUCTING MAGNETS FOR TRAVELING-WAVE MASER APPLICATION.
Abstract
The report presents the results of an investigation to determine the feasibility of incorporating superconducting magnet techniques in the design of traveling-wave maser systems. Several different types of magnet configurations were investigated: isemagnets, Helmholtz coils, modified Helmholtz coils, air-core solenoids, and magnetic end-loaded air-core solenoids. The magnetic end-loaded air-core solenoid was found to be the best configuration for the S-band maser under consideration. This technique yielded relatively large regions of field homogeneity with relatively small aspect ratios (length of solenoid/diameter of solenoid). Several small-scale models of full-length superconducting magnets and foreshortened end-loaded superconducting magnets were constructed using un-annealed niobium wire. Measurements have shown that these magnets were adequate for traveling-wave maser applications that require magnetic fields up to 2,200 gauss and marginal for magnetic fields up to 2,500 gauss.
