This is a coupon sample holder for the 650Mhz cavities research and development. Made completely from niobium (except the bronze mounting ring) in the Village Machine Shop, the holder allows for easier swapping of samples and sensor placement. The design, featuring a compound curved shape, milled into niobium surface, was created by Tim Ring. Photo: Eddie Pieszchala
