摘　　要：Two soft X-ray pulse height analysis （PHA） systems, based on silicon drift detec- tor （SDD）, were established on the experimental advanced superconducting tokamak （EAST） to measure spectrum of soft X-ray emission. In this paper, the soft X-ray PHA systems on EAST are introduced and some experimental results of electron temperature in EAST obtained from the soft X-ray PHA diagnostic are presented.Two soft X-ray pulse height analysis （PHA） systems, based on silicon drift detec- tor （SDD）, were established on the experimental advanced superconducting tokamak （EAST） to measure spectrum of soft X-ray emission.
