PyHEADTAIL v1.3.1

Minor bug fixes for setup.py, WakeTest.ipynb, versioning without git and README.

PyHEADTAIL v1.3.0

New features:

• RFBucket Hamiltonian supports other potentials
  and fields (like space charge)
• Multiturn wakefields
• higher-order chromaticities (arbitrary order)
• dispersion supported
• unit tests
• beam optics (optics functions like the beta function as
  inferred from the beam solely via statistical methods)
• full phase advance for each segment (in addition to
  previous calculation of phase advance proportionally to s)
• new SliceSet interface with statistics saved at creation for the slices
  and slice profile / derivative profile, also beam properties are taken over
• Bassetti Erskine space charge
• performance optimisation

PyHEADTAIL v1.2.0

RFSystems Interface Change

• Kick objects and Drift objects are now completely hidden behind RFSystems,
  do NOT use them anymore
• all RF parameters (only!) available via

$ >>> longitudinal_map = RFSystems(...,
some_harmonics, some_voltages, some_phi_offsets, ...)
$ >>> list(longitudinal_map.voltages) == some_voltages
True
$ >>> list(longitudinal_map.harmonics) == some_harmonics
True
$ >>> list(longitudinal_map.phi_offets) == some_phi_offsets
True

• in the context of the RF parameter interface, general.utils.ListProxy
  has been added
• RFBucket instances are now ONLY fixed blueprints
  (same concept as for SliceSet instances).

Access the current state of the RF bucket configuration
(for Hamiltonians and matching) via

$ >>> longitudinal_map.get_bucket(some_gamma)

This release has been tested with the PS transition situation.

Attention:
It is discouraged to store slice views (blabla = rfsystems.voltages[2:4])
of the RFSystems parameter interfaces.
(Reason: their internal reference lists are not updated if
RFSystems._kicks is restructured (via pop etc))

PyHEADTAIL v1.1.1

Minor changes / adaptions to the new, fixed implementation of the aperture module
(see PyHEADTAIL v1.1.0):

• Aperture module: Update docstrings, remove obsolete apply_losses_here,
  pass along consistently the *args, **kwargs.
• Particles module: Update docstrings.
• ApertureNLosses interactive test: use new implementation of the aperture module.
• setup.py: remove the obsolete particles/cython_functions.pyx module.

PyHEADTAIL v1.1.0

Add losses - remove views, instead use arrays with alive particles directly.

PyHEADTAIL v1.0.15

Added 64 bit compatibility to aperture module.

PyHEADTAIL v1.0.14

• New feature: apertures and particle losses.
• In Wakes module:
  Make function_longitudinal(..) and function_transverse(..) public and
  clean up redundant code.
• In Particles: add(..) method now takes dictionary as argument.

PyHEADTAIL v1.0.13

• In AmplitudeDetuningSegment: Include alpha_{x,y} in
  calculation of transverse action.
• In Resonator and ResistiveWall WakeSources:
  Rename Yokoya_Z parameter.
• In Resonator: clean up methods _function_transverse and
  _function_longitudinal (remove R_shunt, frequency, Q from args.
  Access them directly using self. ...).

PyHEADTAIL v1.0.12

Replace reference in the particles update method by copy.
Does require numpy arrays at this stage.

PyHEADTAIL v1.0.11

Improved matching using semi-analytic evaluations for better
convergence of longitudinal emittances.
