Nonlinear Beam Physics

Author

  • Benjamin Folsom

Summary, in English

A condensed treatment of conventional beam physics (both linear and nonlinear) is given for the non-expert; this constitutes a minimum knowhow for constructing simulations of rudimentary beamlines. The criteria for an ideal nonlinear charged-particle simulation algorithm are then presented, leading to the derivation of a symplectic, explicit, Lorentz-covariant integrator.
Space charge (inter-particle interaction) is addressed next, with a first-principles approach based on the Liénard–Wiechert potentials. A cumulative chapter follows, applying the developed simulation methods to multipole magnets (sextupoles, octupoles, and higher-order) which have inherently nonlinear potentials.
A concluding chapter proposes applications for nonlinear simulation of neutron particle dynamics in terms of magnetic dipole moment steering.
