Preliminary design parameters were established for a traveling-wave configuration of the 70 gc maser. The feasibility of using a traveling wave structure depends critically upon the avail ability of a suitable isolation material and upon the development of microwave matching techniques. Several ferrite isolator materials have been tested as a function of resonant frequency versus magnetic field at room temperatures and at liquid helium temperatures. Rutile maser materials, having a very high dielectric constant, are difficult to insert into the microwave circuitry without causing very large mismatches. There fore, the design of proper matching devices and configurations has been of primary concern during this period. A computer program was established during this period to solve the steady state rate equations for the iron ion in rutile. Since the relaxation rates are not known with sufficient accuracy, the results of the program are somewhat inconclusive.
