v8.2.0

[giadarol]

New features:

• Cross-ionization: ionisation of residual gas by the existing ions and electrons in the chamber (thanks Lotta!).
  • More information can be found here
• Computation and logging of stored electric energy.
• Forces on electrons can be optionally calculated using electromagnetic potentials instead of quasi-static approximation (thanks Lorenzo!).
  • More information can be found here.
  • Cython implementation of Boris tracker can now handle longitudinal magnetic field.
• Simple parallelization for buildup simulation (only single-grid supported for now)
  • An example can be found in /testing/parallel_buildup.
• Improvements in photoemission module:
  • Source of photoemission on the chamber in the horizontal plane can be specified by setting x0_refl = 'left' or x0_refl = 'right'.
    • Check that specified outer circle is fully outside the chamber.

This version of PyECLOUD is compatible with Python 3.

• Python 3 code can be generated using the script generate_python3 in the main folder.
  • The script should be called after setup_pyecloud is executed (the .so objects must be in place)
• Similar scripts are available also in PyPIC, PyHEADTAIL and PyPARIS.
• PyKLU and NAFFlib are natively compatible with Python 3.
