PyECLOUD Version 8.7.1

Fix:

• Fix compatibility issues with latest python and numpy versions.
• Tested to work with Linux, MacOS and CERN's lxplus.

Recommendation to use Miniforge3 instead of miniconda, and install compilers through conda.

PyECLOUD Version 8.7.0

New features:

• Saving the .mat file ouput file only every Nth bunch passage (save_mat_every).
• Loading longitudinal magnetic field from file.

Fix:

• Changes np.int to int to remain compatible with latest version of numpy.

PyECLOUD Version 8.6.0

New feature:

• Introduced in Furman-Pivi model limits for angular dependence of backscattered and rediffused electrons.

PyECLOUD Version 8.5.1

Fix:

• A small fix in mystyle module

This version of PyECLOUD is incompatible with Python 2.

PyECLOUD Version 8.5.0

New feature:

• Tool for the characterisation of dipolar and quadrupolar forces on the beam

Fix:

• Minor fixes in the mystyle module.

This version of PyECLOUD is incompatible with Python 2.

PyECLOUD Version 8.4.2

Fix:

• Minor fixes in the mystyle module.

This version of PyECLOUD is incompatible with Python 2.

PyECLOUD Version 8.4.1

Adds small features:

• Example script to follow a subset of the electrons
• Flag to enable/disable legacy matplotlib style

This version of PyECLOUD is incompatible with Python 2.

PyECLOUD Version 8.4.0 (python 3)

New features:

• Boris multipole can handle a longitudinal uniform magnetic field (solenoid)
• Documentation PyEC4PyHT module

PyECLOUD Version 8.3.0 (Python 3)

New feature:

• Re-interpolate fields from beams and clouds at each Boris sub-step.

This version of PyECLOUD is incompatible with Python 2.

PyECLOUD Version 8.2.0 (Python 3)

Python 3 version of PyECLOUD v8.2.0

New features in v8.2.0:

• 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 incompatible with Python 2.
