This new cavity has been designed to withstand a 700 kV peak voltage and a 140 kW dissipated average power. Although very similar in its geometry to the original flat top cavity currently in operation, in the new design, special attention has been paid to the shaping of the four electrodes for maximizing the shunt impedance. Furthermore, the topology of the cooling water channels has been optimized to increase the power handling capabilities of the cavity. Finally, in order to mitigate multipacting observed in the current design, variations on the new cavity baseline geometry have started to be explored.
