A ferroelectric electron gun was designed and fabricated. The simulation and preliminary experimental results of the gun are reported. The gun uses a planar Ba0.67Sr0.33TiO3 (BST67/33)cathode in a Pierce geometry. The gun voltage can reach 80 kV with the pulse width of 80 ns. The designed perveance of the gun is 0.15×10-6 A·V-3/2. In the experiment, the gun voltage gradually increases from 30 kV to 56 kV, and the emission current increases from 0.7 A to 2.5 A. The perveance of the gun is measured as 0.2×10-6 A·V-3/2, mearly the same as the designed value.
