To provide a manufacturing method of a superconducting radio-frequency acceleration cavity used in a charged particle accelerator enabling the manufacturing with few waste amounts of the niobium material at low cost in a short time, the manufacturing method has each of the steps of (a) obtaining an ingot made from a disk-shaped niobium material, (b) slicing and cutting the niobium ingot into a plurality of niobium plates each with a predetermined thickness, by vibrating multiple wires back and forth while spraying fine floating abrasive grains with the niobium ingot supported, (c) removing the floating abrasive grains adhered to the sliced niobium plates, and (d) performing deep draw forming on the niobium plates and thereby obtaining a niobium cell of a desired shape.

A method for providing a superconducting surface on a laser-driven niobium cathode in order to increase the effective quantum efficiency. The enhanced surface increases the effective quantum efficiency by improving the laser absorption of the surface and enhancing the local electric field. The surface preparation method makes feasible the construction of superconducting radio frequency injectors with niobium as the photocathode. An array of nano-structures are provided on a flat surface of niobium. The nano-structures are dimensionally tailored to interact with a laser of specific wavelength to thereby increase the electron yield of the surface.
