In this paper, we introduce the first ultrahigh electron experiment in the experiment of large-energy light-frequency black-cavity cavity in ShenGuang II, and use a 10-channel fluorescence spectrometer (FFS) to measure the hard target emission from 1 5-25 keV hard x- Radiation spectral flux deduces that the fraction of superheated electrons accounts for 13% -16% of the incident laser energy, and the extrapolated electron temperature Th is 35-45 keV from the slope of the spectrum and is determined by the superheat electron energy and stimulated Raman scattering light ( SRS) energy, infer the mechanism of superheated electron generation, and give the characteristics of superheated electrons generated by different cavity targets under different laser energy EL
