Multi-Turn Extraction

 Simulation Movies

 Some simulation results are shown here. They refer to the proposed adiabatic capture of charged particles in stable islands of transverse phase space.

 In the movie the evolution of the beam distribution (special Courant-Snyder co-ordinates) is shown together with the tune-variation used to capture the particle in the stable islands.

• Third-order resonance
• Fourth-order resonance

 Attempts to analyse a model describing the combined effect of non-linearities and radiation damping have been made. Some notes are repoted later:

• Hénon map with damping
