Abstract : Progress was continued on the tube and filter development. In the tube area, the following took place: 99 percent transmission of the beam through the helix; stable emission of 4 amps/cm2 from the cathode face; synchronous helix voltage within 5 percent of design; 30 db electronic gain at 78 kmc. In the filter area: 3 to 3.3 db resonant and insertion loss from 70 to 85 kmc at a 3 db bandwidth of 80 to 84 Mc. Three .016 inch diameter YIG spheres of line width less than 0.5 orsted were used.
