- A quarter wavelength resonant parallel plate transmission line to be used to supply energy for acceleration heavy ions is described. The operating frequency of this low beta structure will be 2 megahertz. This resonator will be chiefly in air and provide means of transforming radio frequency power from a 20 kilowatt transmitter up to 100 kilovolt peak gap voltage. In the intended 20 gap structure this will result in a total peak voltage of 2 million volts. The transmission line configuration chosen lends to in-house fabrication resulting in time and cost savings. The line is driven in push--pull and can be split into two transmission lines near the high voltage vacuum window region which enters the accelerating structure. This reduces the voltage hold off requirement to 50 kilovolts in the window area. Parameters of the line are calculated, including characteristic impedance and theoretical Q. Electrical and magnetic field configurations in the line are given. Impedance matching relationships between the transmitter and line for optimum power transfer are developed. The expected voltage and power relationships are then derived.
