Abstract

Abstract:

Magnetic field distribution of the ECRH superconducting magnet on HL-2A tokamak has been measured, and the results show that the normalized axial magnetic induction is not less than 0.992 in the area of 20mm around the center, the fluctuation of magnetic field is not more than 1.48% on the whole center plane, the stray field near the magnet surface is not more than 50mT; and these satisfy the experiments.

Key words: ECRH, Superconducting magnet, Magnetic field distribution
