Definitions
- Previous ion sources also require proper positioning and placement of electrodes. This becomes more complex as a greater number of precisely positioned electrodes becomes necessary. If any of the electrodes are improperly focussed or positioned, the ion stream created by the ion source may lose focus. The problem of placement is exacerbated by the use of thin sheets of bendable metal for electrodes. Improper handling and installation of these electrodes can result in loss of precision.
