Popis: The highly energetic high fluence argon ions that are generated in dense plasma focus (DPF) device are used for the first time for the enhancement in Tc of superconducting BPSCCO thick films. These films are in mixed phase 2212 (Tc=85 K) and 2223 (Tc=110 K) prepared by screen printing technique. They are exposed to the ions of DPF axially above the anode at various distances. Tc of the films irradiated at a particular distance have been found to increase with maximum of 15 K. XRD peaks also confirm the presence of high Tc (2223) phase of BPSCCO only, for the films for which increase in Tc is 15 K.
