Beam position monitor challenges


Wide range of currents
Tight requirements for position accuracy for intense
beams – Δx < 0.1mm, x = ±100mm
Beam position monitor features
 A special attention to pick-up construction
 Careful design of front-end electronics

Secondary emission monitor
Construction drawing (overview from the front side) of a typical profile grid. To reduce the
number of required signal processing channels, a larger spacing outside the center has been
chosen.
Roughly estimated number of secondary electrons per incident ion with the energy of
incident ion as a parameter. The data have been scaled ~z1.5 from various data found in the
literature
