Abstract : A new method of casting abrasive rings for the tunnel air races has been devised, resulting in greater productivity and reduced down time. The new sphere encap sulation and alignment process has been fully developed and tested. This process yields greater speed and accuracy, resulting in an increased production capability. The second delivery of limiter engineering samples was shipped during this reporting period. Design goal characteristics were not accomplished in all units. Machined and purchased parts are being prepared for the fabrication of the preproduction units. Test specifications and procedures are being drawn up for use in testing these units. YIG material has been fired to demonstrate reproducibility and to study the distribution of magnetization values in gallium substituted material. Satisfactory results were indicated in both cases.
