500 MHz Coaxial Transition between the Elettra Input Coupler and the Transmission Waveguide

The investigations have shown that the 500 MHz ELETTRA Input Power Coupler (IPC) can safely sustain more than 150 kW. The critical component limiting the increase of the transmitted RF power is the connection element between the input power coupler and the transmission line. An optimized design has been studied to overcome this limit. During the optimization process, the entire RF chain (input power coupler, connection element and transition to the standard waveguide WR1800) has been verified. The analysis has been carried out to check the performances of the whole lay out in terms of efficiency of transmitted power and sensitivity to any signal coming from the cavity.
