Description

The new spin dynamics simulation suite POLE is designed to perform systematic studies of polarization in circular accelerators with fast energy ramps, or short storage times of up to some seconds. A main application is the investigation of crossing depolarizing resonances depending on arbitrary magnet and optics settings. For instance, many simulations of a single resonance crossing are performed with varying correction schemes. POLE uses spin tracking and applies frequency filters to the magnetic fields to balance accuracy against computing time. Thus, the step sizes during tracking can significantly exceed the length of a magnet. In order to keep short computing times, synchrotron radiation effects are modeled by a simplified time course of the particles energy. Additionally, multiple spins are tracked simultaneously on multi-core processors. POLE automatically computes the required magnetic field data based on a common lattice file from MAD-X or Elegant.
