Summary
Travelling wave accelerators can be built either with constant impedance or constant gradient structures. Whereas for the constant impedance case the geometry of the cells does not change, the iris size in a constant gradient structure is decreased from cell to cell in order to slow down the power flow of the incoming rf pulse by reducing the group velocity in order to achieve P'(z) = const. Changing the phase advance per cell for the accelerating wave from the beginning towards the end of the structure provides as well a constant power loss per unit length and has the additional advantage of equal iris diameters over the entire length of the travelling wave tube. Concerning short and long range wakefields, dark currents and mechanical demands, this type of constant gradient structure is discussed in comparison to the conventional one. 9 refs., 4 figs., 2 tabs.
