Abstract : A 35 gigacycle linear bunching accelerator which has a non-uniform, disk-loaded waveguide as an accelerating structure is described. An accelerator which theoretically requires 75 kilowatts of pulsed 35 Gc microwave power to accelerate a 20 milliampere beam to a velocity of 0.776c has been designed and constructed. The attenuation of and the power flow in the non-uniform structure are analyzed. Fabrication techniques for construction of the disk-loaded waveguide are described. The measured output velocity of the electrons is within one per cent of the theoretical value. A design for an accelerator which requires 125 kilowatts of pulsed 35 Gc microwave power to produce a 20 milliampere beam with a velocity of 0.9c is presented and is shown to be quite feasible.
