PyHEADTAIL v1.13.3

Changes:

• generate transversely cut distributions (e.g. a Gaussian distribution cut at 3.4 RMS amplitudes): supported in generators.generate_Gaussian6DTwiss via keywords limit_n_rms_[x,y,z] in all 3 planes.
  --> The concept is demonstrated in the PyHEADTAIL-playground repo (GeneratorTest).

PyHEADTAIL v1.13.2

Changes:

• aperture bugfix when running on the GPU with slicemonitors (thanks Eirini!)

PyHEADTAIL v1.13.1

Few corrections (adapting license and adding pull_request_template) and adding Gianni's python 2-to-3 script.

PyHEADTAIL v1.13.0

Changes:

• license: 3-clause BSD license
• wakes: adding vertical parallel plates, renaming horizontal ones
• longitudinal: adding square-well potential (ABS beams)
• feedback: ideal transverse damper now also includes reactive part (see PyHEADTAIL-playground)
• monitors: fixing CellMonitor also for GPU (now used in production)
• wakes: bug fix in resistive wall scaling
• generators: bug fix in kv2D
• context management: fixed and new functions
• generators: function to accept generated particles only within certain action (useful especially for linear generators)
• setup.py: speeding up cython (removing profiling flag)

PyHEADTAIL v1.12.4

Changes:

• hotfix: CUDA 9.1 compatibility
  (thrust::gather has been moved to thrust/gather.h)
• include cellmonitor (cf. #75)

PyHEADTAIL v1.12.3

PyHEADTAIL v1.12.3: adaptive frozen space charge

Changes:

• bug fix for field map calculation in FrozenGaussianSpaceCharge
• FrozenGaussianSpaceCharge can recompute field map from beam
• new automated adaptive mode for FrozenGaussianSpaceCharge
• PIC / self-consistent space charge: same new automated adaptive mode implemented in SpaceChargePIC_Adaptive25D

PyHEADTAIL v1.12.2

Bugfixes and more flexibility for damper

• feedback: include damping rate 0 treatment
• frozen space charge field map: bug fix of vertical plane

PyHEADTAIL v1.12.1

New feature for FrozenGaussianSpaceCharge25D: providing adaptive mode

The fields are automatically recomputed when the beam RMS size changes. This is controlled via sigma_rtol.

PyHEADTAIL v1.12.0

Changes:

• Longitudinal RFBucket matching has been upgraded, support of thermal,
  q-Gaussian, parabolic and waterbag distributions. Can easily be extended
  to new distribution types. Make sure to check out the notebook
  https://github.com/PyCOMPLETE/PyHEADTAIL-playground/RFBucket_Matching.ipynb .
• New FieldMap classes for 1D (horizontal), 2D (transverse) or 3D field maps
  including the GPU (uses PyPIC).
• New FrozenSpaceCharge25D allows to apply a frozen transverse field map to a
  bunch in slice-by-slice manner, where the longitudinal plane is self-consistently
  resolved via slicing by using the local line charge density for the field map.
• New PyPIC version significantly speeds up self-consistent PIC space charge
  on GPU (cf. message of commit 28e3cc5 for timing details).
• Self-consistent PIC space charge uses double precision by default now.
• 2D PDF integrators revived and restructured.
• RFBucket allows proper PS Booster accelerating bucket description now (cf. commits d49c460 and 2355c13).
• Release script includes PyPI publication now.
• Minor documentation improvements.
• Some (relevant) bug fixes.

PyHEADTAIL v1.11.6

Hotfix: removing pylab imports from feedback module

Furthermore, this PR extends the release script functionality:

• allow releasing patches from hotfix/* branches
  (cf. branching model on wiki)
• draft github release form CLI (via gothub tool)
