Quality of Inward Curved MgB2 Films Prepared by HPCVD PROJECT TITLE :Quality of Inward Curved MgB2 Films Prepared by HPCVDABSTRACT:Arising from the superconductivity at ∼thirty-nine K, magnesium diboride (MgB2) films have great prospect in the field of superconducting radio-frequency (SRF) cavities. To match the geometrical shape of the inner surface of the SRF cavities, the deposition techniques for inward curved MgB2 superconducting films are explored. By using pre-bent metallic substrates, curved MgB2 films were deposited in situ. These curved films show properties comparable with those of the films deposited on a plane surface. Even when the curvature radius of the films is as tiny as ∼a pair of mm, the superconducting transition temperature of the films reaches ∼thirty six K. The in situ-grown films were conjointly compared with the films prepared by postdeposition bending. Within the bending of , of the films falls off to 25 K, much not up to that of the in situ-grown films with the identical . The scanning results of electron microscope indicate that the wrinkles and cracks showing within the bending are the main reason for the degradation of transition temperature.
