Ten modules of the integrator system of the initial magnetic diagnostics for the first plasma operation have been simultaneously tested in the Korea superconducting tokamak advanced research device by measuring the magnetic flux density from various magnetic diagnostics sensors when a small current was applied to the superconducting poloidal field coils. The measured drifts from the integrators show between 1×10-6 and 1×10-5 Wb/s. The results from the field tests before the first plasma generation are described.

    It has been seen that a plasma produced by a Marshall gun can be injected into and trapped by a tokamak plasma. This trapping of a gun-injected plasma is explained in terms of a depolarization current mechanism. A model is developed that describes the slowing of a plasma beam crossing into the...
