To improve the accuracy of the magnetic field of Ring Trap-1 (RT-1), we have constructed a system of correction coils to cancel the geomagnetic field and control the attitude of the floating magnet. Without the geomagnetic field canccellation, the floating magnet tilts about 1.4 degrees. The previous prototype correction coils have been replaced by new coils that are much larger and farther from the chamber, so the error field due to the multipole components of the correction field is reduced by a factor of 30 (from 2.6% to 0.1% of the confinement field near the edge region). A significant improvement in plasma confinement has been observed (the stored energy of the plasma has been increased by a factor of 1.5).
