A 12.5-m long Self Magnetically Insulated Transmission LinE (SMILE) that sums the voltages of 8, 2-MV pulse forming lines was installed in the RADLAC-II linear induction accelerator. The magnetic insulation criteria was calculated using parapotential flow theory and found to agree with MAGIC simulations. High quality annular beams with β ⟂ ≤ 0.1 and a radius rb < 2 cm were measured for currents of 50-100-kA extracted from a magnetic immersed foilless diode. These parameters were achieved with 11 to 15-MV accelerating voltages and 6 to 16-kG diode magnetic field. The experimental results exceeded our design expectations and are in good agreement with code simulations.
