Description
In order to reduce the cost of superconducting cavities, we propose a new method of manufacturing cavities using 0.2 mm thick niobium foil tubes. We came up with the idea of applying a plastic processing technology called elctromagnetic forming (EMF). As a result of a feasibility study, we found that niobium is a difficult material to form by EMF, and experimental results showed that it was almost impossible to form. Therefore, we tried a method of forming niobium by layering copper or aluminum materials called drivers on niobium, and felt that it was possible to form it. We report the experimental results so far.
