Diamagnetism measurements in the Hanbit magnetic mirror device

Abstract

The diamagnetic effect is measured by using the diamagnetic loop with a compensation loop in the central cell of the Hanbit magnetic mirror device. To ensure reliable measurement, the influence of nearby conductors on the diamagnetic loop signal is investigated, and the output voltages during a pulsed vacuum field are measured to calibrate the loops installed inside the central cell. The diamagnetic measurement is carried out during rf discharges with a frequency of 3.75 MHz and heating power of up to 150 kW. In the measurement, the vacuum field of 0.126 T is applied in the central cell. The results from the experimental measurements are presented.
