ACCELERATOR GRID TESTS ON AN ELECTRON-BOMBARDMENT ION ROCKET

Technical Report ·
OSTI ID:4803652
A systematic investigation of screen-accelerator grids was made with an ion rocket having a 10-cm-dia. electronbombardment ion source. Mercury ion beams of 0.03 to 0.44 ampere were operated at net accelerating voltages of 900 to 6100. The experimental work was conducted in a bell jar connected to a vacuum tank of 5- ft-dia. and 16-ft length. Various multihole grid plate spacings, hole sizes, plate thicknesses, and grid materials were studied. Data are presented for 15 different sets of screen-accelerator multihole plate grids and, for comparison, wire grids. (auth)
