In this paper the feasibility of Fe(Se,Te) Coated Conductors (CC) on simple Rolling-Assisted Biaxilly Textured Substrate (RABiTS) template is studied. Starting from commercially available NiW5% tapes from Evico which have an out-of-plane orientation of about 6° and an in-plane orientation of 5.3°, a RABiTS template for Fe(Se,Te) coated conductors was realized depositing CeO2 thin films on the metallic tape. The oxide buffer layers, deposited via Pulsed Laser Ablation, have an out-of-plane and an in-plane orientation suitable for Fe(Se,Te) deposition and act as a chemical barrier against Ni diffusion. The Fe(Se,Te) deposited on such a simple template show a superconducting transition Tc of 18 K, very high upper critical field values with a Tc,0 of only 3 K in 18 T and self-field transport isotropic critical current values of 10 5 A/cm 2 at 4.2 K, which is reduced of less than one order of magnitude up to 16 T.
