摘要：
We describe the design and operation of a long-pulse (200-300 μs), high-duty-cycle (5%-6%), 8-mm-diam dispenser cathode, electrically isolated, modulating Wehnelt electron gun for applications in a high-average-power electron linear accelerator. The electron optics design was optimized with computer modeling of the electron trajectories and equipotentials. The gun performance was established in a series of experimental measurements in a test stand. Excellent pulse-to-pulse emission current reproducibility and electron-beam pulse profile stability were obtained.
