| Abstract: | Deposition of diamond like carbon (DLC) films on YBCO superconducting detectors is reported. The method is to make a DLC film by C+ implantation and XeCl excimer laser irradiation. The implantation energy is 20–35 keV and C+ implantation dosages D=1×1014–5×1018 ions/cm2. The parameters of XeCl excimer laser ablation are: wavelength, 308 nm; energy density, 20–50 mJ/cm2; and width of pulse, 45 ns. The superconductivity of C+-implanted YBCO is also investigated, while the damage behavior of C+ implantation and the mechanism of coating DLC are analyzed. |
