WebWith a focused ion optics design, the ions converge to a focal point downstream of the grid exit plane. With a collimated ion optics design, the ions exit the grid with a trajectory nearly parallel to the ion source axis. These unique beam shapes are then matched to the appropriate ion beam process. Decoupled Ion Energy and Current http://www.platar.ru/P2E.html WebThree-grid ion optics consists of three perforated grids. These systems provide a smaller divergence of ion beams with energy up to about 500 eV than two-grid systems. Besides, three-grid optics allows decreasing a beam contamination connected with sputtering of an accelerating grid by charge-exchange ions. Defocused ion optics includes convex ... grandma\\u0027s attic thrift store
