Abstract: The principle and method of emittance measurements for pulsed intense electron beams using a multipinhole pin mask is described in the article.The effects of space charge and axial magnitic field on the measurements were considered.The experimental parameters were cathode type,anode mask texture.diode spacing and voltage,and beam current.A Em_rms value of the emittance) of 79 cm.mrad was obtained with a planar velvet cathode an etched tungsten mask anode at the beam energy (E) of 1.32 MeV and the beam current (I) of 2kA on the LIA,corresponding normalized brightness (B) was 4.8 ×10³ A (cm.rad).
