Buncher Lens Example

_images/buncher.png

Buncher lens example (“buncher”). The problem is to slow a packet of ions so that they converge in time. The trick is to have them decelerate in a linear field and then (when they are in the middle of it) chop the field to zero. Thus the leading ions will be going slower than the trailing ions and they will bunch together at some point down stream.

Ions in flight, along with a trace of times of ion splats against the electrode. Notice that ion splat times are near identical, as desired in an ion buncher.

Lens Tuning Example

_images/tune_view3d.png

SIMION “tune” example, showing a user program to tune a lens. A simple three element fast adjust lens is provided for tuning. The middle electrode is adjusted via user program. This should serve as a simple example of how tuning problems might be approached.
