Abstract : The new X-band Orthotron was designed in detail. The anode has twelve uniform cavities and has an active length of 5.6 inches or four wavelengths. Identical input and output couplers are used at opposite ends of the anode. The input signal excites the pi mode on the anode structure. The wave is amplified as it travels along the tube and is then coupled to the output waveguide. The dimensions of the couplers and the design of the selective mode absorbers have been determined by cold testing. The tube consists of eight main subassemblies which will be welded together. All parts were fabricated, and the subassemblies are being brazed. The long anode vane structure was electrical-discharge machined from a solid copper cylinder. The axial magnetic field required for operation will be provided by a three-section solenoid. This magnetic circuit and the waveguide circuitry necessary for testing were obtained and calibrated.
