  • Abstract
    Comparative measurements of sheet metal and sputter coated Nb cavities were performed at 500 MHz. The sputter coated ones had a higher low field Q, a stronger decrease of Q with the accelerating field, and showed no static magnetic field dependence of the Q value. Throughout the layer, larger amounts of impurities were found, which may explain the experimental results.
