Beam sources
Jan 1, 1989 · General description. Most broad-beam ion sources used in thin-film applications are gridded, that is, the ions are accelerated by the electric field established between ion-optics grids. The schematic diagram of a gridded ion source and its controller is shown in Figure 1. A cutaway sketch of a gridded, broad-beam ion source is shown in Figure 2. Oct 13, 2023 · A connector usually consists of a source and a sink. All Beam sources and sinks are composite transforms; however, the implementation of your custom I/O depends on your use case.

This translates into well over 1000 hours of beam production time. The lifetime of a cathode is highly dependent on the sputter rates. However, the source is designed to allow the change of a cathode without turning the source off. In Pelletron® systems, it is common to change a cathode within 10 minutes from beam on target to beam on target.Timing. The best way for students to become acclimated to the BEAM/BEAT framework is through repetition.
