PS Continuous Transfer Beam Slicing Scheme

The proton beam to be ejected is kicked partly onto a very thin electrostatic septum. A fifth of its intensity is sliced off at each passage. The beam remaining in the PS returns with a 90° anti-clockwise rotation for a further slice. Thus, after 5 turns, a long continuous beam of quasi constant intensity is obtained. The method has been likened to an apple-peeling scheme.
