Description

This talk presents an overview of the efforts to resolve niobium quality issues, specifically surface pits and delamination, encountered during cavity manufacturing for the PIP-II project. Initial surface quality problems led to a temporary suspension of production. Additionally, delamination was later discovered in both formed and unformed sheets, raising concerns about the material's integrity across multiple projects. This poster will detail the challenges faced, the investigative process, and the solutions implemented to restore and enhance the quality of niobium used in cavity manufacturing.
