MP00 Ion Optics
The MP00 ion optics (Figure 13) include the MP00 RF lens and the L0 lens.
The MP00 RF lens is an array of eight metal elements. The MS applies an RF voltage to the
elements to generate an electric field that guides the ions along the axis of the lens.
The lens L0 is a metal disk with a small hole in the center through which the ion beam passes.
The MS applies an electrical potential (positive for positive ions and negative for negative
ions) to lens L0 to transmit ions of the selected charge. Lens L0 acts as a baffle between MP00
and MP0 to isolate the lower vacuum region.
