Xtrack version 0.14.5

New feature:

• Possibility to skip kernel compilation when creating tracker (to access the source without compiling)

Xtrack version 0.14.4

Changes:

• Add copyright statement to all files
• Add license file
• Add metadata in setup.py

Xtrack version 0.14.0

Change:

• Definition of longitudinal coordinate zeta changed from zeta = s beta/beta0 - beta c t to zeta = s - beta0 c t.

Xtrack version 0.13.0

New features:

• io_buffer and internal records for data logging inside beam elements
• Logging of emitted photons in Multipole
• possibility to unfreeze a line (invalidating the associated tracker)
• Fix in synchrotron radiation

Xtrack version 0.12.0

Changes:

• Introduced FirstOrderTaylorMap.
• Tracker can start and stop at any element of the line both in collective and non-collective mode.
• LossLocationRefinement by default allows backtracking only through a restricted list of element types.
• Fix initialisation fo random number generation by Tracker in collective mode.
• Preserve order of elements at the same s coordinate when imported from MAD-X.
• Import polygon aperture from MAD-X.
• Import deferred expressions from MAD-X in Wire element.
• Moved generation of Line from sixtrack input to sixtracktools package.

Xtrack version 0.11.4

Changes:

• Adapt to Xdeps v0.0.5 API
• Removed default to zero for variables used in Xdeps expressions (default is disabled after MAD-X import)

Xtrack version 0.11.3

Changes:

• Introdude multi-frame mode in ParticlesMonitor
• Added examples for ParticlesMonitor usage

Xtrack version 0.11.2

Fix:

• Particles of species different from the reference particle correctly propagated in LossLocationRefinement

Xtrack version 0.11.1

Changes:

• Global aperture check can be disabled passing Tracker(..., global_xy_limit=None).
• Particles lost on the global aperture limit are identified by -1 in the particle state.
• Fixes in LossLocationRefinement: correct propagation of global aperture settings, correct charge and mass in refinement (and in BeamInteraction. Global aperture check is disabled for backtracker.

Xtrack version 0.11.0

Changes:

• Changed stored energy variable from psigma to ptau
• Cleaned up examples for mixed cpu/gpu simulations and for ring with synchrotron radiation
• MAD-X loader uses angle variable instead of knl[0] to set reference system curvature (used in tapered lattices)
• Dispersion calculation accounts for energy loss along the beam line (needed in presence of strong radiation)
