We will review recent advances for ultra‐high gradient‐linac. We will show how the research on the basic phenomena of microwave breakdown in ultra‐high vacuum structure, led to novel geometrical designs that allow electron linac to achieve gradients in excess of 140 MV/m. Also, with the usage of copper alloys, one would hope to push this gradient to 180 MV/m. these advances can be applied to proton linacs. We will present suggested designs for future proton linacs, which would push the gradient to more than 70 MV/m. These will operate at high frequency in the X/Ku band. With this technology one hopes to design compact proton therapy machines at energies of ∼ 250 MeV, with fine control of energy. The compactness of the linac might allow the whole system to be installed on a single gantry.
