  • Abstract
    The development of high current density sheet beam electron gun for Terahertz devices is carried-out. It operates at beam voltage of 12 kV and perveance 0.0136 mup to meet ours requirement of high beam current density 100 A/cm2 and low emittance 0.068 pi-mm-mrad at the beam-waist position. Currently, mentioned gun is being fabricated. Work has been initiated to test the performance of Scandate cathode using anode-aperture mapping. Current density of 50 A/cm2 has been ensured across the beam cross-section of 100 times 600 mum2.
