摘要

A seven-channel NaI(T1) detector array installed on an HT-7 superconducting tokamak has been used to detect the hard X-ray (Ehv＞20 keV) emitted from the plasma. The physical mechanism of the lower hybrid waves propagating and absorbed in the plasma is investigated by the measurement of the hard X-ray radial profile at different discharge parameters.
