• Purpose of the code :

  Simulate beam-electron cloud interactions and instabilities in circular accelerators; goal is to provide high-fidelity via parallelized particle-in-cell model with arbitrary initial cloud distribution specified all along the ring.

• Special model features :

  1) a moving simulation window that follows the beam
  2) the code separates 3-D from 2-D time scales and reduces computation time by a huge amount
  3) it uses the local nature of wake equations to form 3-D wakefields from a sequence of 2-D Poission solves.
