After briefly analyzing the technical difficulties of diagnosing high fluence electron beam,three new methods for diagnosing parameters, including filtered Farady cup for measurement of the electron transient effective incident angle,Farady multi-cup for measurement of the time-resolved current density and graphite calorimeter for measuring the total beam energy with correction, are presented. In the condition of space voltage 1.08MV and current 484kA on the diode of flash-2 accelerator,in the distance 20.5cm from cathode measured is total beam energy of 19.1kJ, and of 22kJ after correction. By means of measurement is presented also radial and azimuthal current density on the beam cross-section in different time, and energy fluence on beam spot center with 13% more than its average valu
