Manufacture of EAST VS In-Vessel Coil

•ITER like Stainless Steel Mineral Insulation Conductor (SSMIC) used for EAST Tokamak VS In-Vessel Coil manufacture first time.•Research on SSMIC fabrication was introduced in detail.•Two sets totally four single-turn VS coils were manufactured and installed in place symmetrically above and below the mid-plane in the vacuum vessel of EAST.•The manufacture and inspection of the EAST VS coil especially the joint for the SSMIC connection was described in detail.•The insulation resistances of all the VS coils have no significant reduction after endurance test.
