Superconducting Radiofrequency Cavities and the Emdrive Project
Operating at temperatures just above absolute zero, superconducting cavities accelerate bunches of electrons and positrons toward the detectors in a proposed international linear collider. Nine smooth cells, polished in all possible ways. Made of the purest niobium. Not a speck of dust or the slightest difference in shape.
