Summary

Silver sheathed thallium-1223 tapes were prepared by a powder-in-tube process. The critical current density of short samples was 18 kiloA/cm2 at 77 K. Longer tapes up to 1.2 m, prepared by sequential pressing, had a critical current density of 12 kiloA/cm2. From these tapes the authors have wound two coils. A solenoid coil with 5 windings was made of 8 tapes with a total length of 4.5 m. At 77 K the critical current of the coil was 23 A in the self generated magnetic field (18 Gauss at the centre of the coil). A pancake coil with 15 windings, made of 5 tapes with a total length of 5 m, generated a magnetic field of 149 Gauss at the critical current of 12 A.
