Superconducting Thin Films on Metals by Pulse Laser deposition at KEK S.Mitsunobu, S.Inagaki, M.Yoshida, K.Saito, H.Nakanishi and M.Wake KEK At KEK, the test of MgB2 thin films on Cu, Ti and Nb by Pulse Laser Deposition(PLD) method based on a fabrication method developed by NIMS have been studied and RF surface resistances have been measured. The direct deposition of MgB2 film on Nb showed two step decrease of the surface resistance. For a TM010 cavity, formed MgB2 films showed no superconductivity at this time due to different heat treatment conditions from disk samples, so we cutting cavity quadruple and one of them used as target. And heat treated as usual. This quadruple shows superconducting transition.
