Description
A pulsed electron gun with a field emission (FE) cathode using the carbon nanotubes (CNTs) has tested. Anode current of 3.0A/cm2 CNT-FE gun was achieved with 8kV acceleration voltage by applying short grid pulses between cathode-grid electrodes in the last year. The heater-fewer guns are desired for various user because of which emits the low emittance, high brightness electron beams. In order to develop such reasonable FE-guns, 100-kV test stand was structured and the anode currents were obtained the value of 100mA. This is equivalent to about 400mA/cm2 of electron beam was emitted from the CNT cathode. With some improvements anode currents of Ampere order is expected. (author)
