First results from tests of high temperature superconductor magnets on tokamak.

Popis výsledku v původním jazyce

The two copper poloidal field coils of the small tokamak GOLEM were replaced by two coils with 6 turns of the 2nd generation HTS (Re)BCO tape, Fig.1. Two liquid nitrogen (LN) cryostats were assembled to cool the HTS tape to below the critical temperatureat which it becomes superconducting. Although it is known that the critical current in HTS strongly depends on magnetic field, for the GOLEM conditions, where magnetic fields at the coil position do not exceed 0.5T, little effect has been observed for perpendicular field up to 0.5T and superconductivity has been achieved at ~90.50K. Plasma pulses were then fired in a normal way and the tokamak operated exactly as expected.
