Abstract :
The design principles for a high-convergence, dual-mode gun, operable over a wide range of perveances without beam degradation, are given. The gun described employs a grooved cathode, a shadow grid at cathode potential, and two control grids. Test results show excellent beam transmission through a drift tube of 10 inches length and 0.1 inches inner diameter.
