Xtrack version 0.7.0

New features:

• Introduced in Tracker element-by-element logging of the particle coordinates
• Improved Tracker.twiss: faster algorithm, introduced integer tunes and phase advances
• Reset s coordinate at the end of each turn

Xtrack version 0.6.3

New feature:

• closed-orbit in LinearTransferMatrix

Xtrack version 0.6.2

New feature:

• Introduced LimitRacetrack

Fix:

• Issue when loading LimitRectEllipse

Xtrack version 0.6.1

Fix:

• Solves issue in conversion of RFMultipole to dictionary

Xtrack version 0.6.0

New features:

• Introduced Tracker.cycle
• Introduced Tracker.twiss
• Introduced Tracker.filter_elements
• Configuration of space-charge lenses is done using Tracker.twiss instead of MAD-X
• Particles for footprint example are generated using xpart
• knl and ksl in Multipole and RFMultipole are linked to bal using xobject.LinkedArray

Other:

• Clean up examples for direct use in documentation
• Tests introduced for mad-x loader, energy ramp, ring with space charge (frozen, quasi-frozen and PIC)
• Added test_data with precisely matched HL-LHC lattice

Xtrack version 0.5.1

Fix:

• Issue in Monitor.to_dict method

Xtrack version 0.5.0

New features:

• Synchrotron radiation (average and stochastic) within Multipole
• Dipolar kicks in electron_lens

Xtrack version 0.4.1

New feature:

• Tracker.find_closed_orbit works also on GPU

Other modifications:

• Slight modifications in example scripts adapting to modified interface of xpart.build_particles(...) and xpart.generate_matched_gaussian_bunch(...)

Xtrack version 0.4.0

Change in the Xsuite package structure:

• The xline package is removed
  • xline.Line becomes xtrack.Line
  • instead of xline.Drift, xline.Multipole etc. use directly xt.Drift, xt.Multipole
  • The Tracker objects are automatically updated when the line is modified (no need to regenerate the tracker)
• There is only one Particles class within Xsuite
  • xline.Partices and xtrack.Particles replaced by xpart.Particles
• The reference python implementation of the main elements, which used to be in xline, is moved to a small package called ducktrack, installed together with xtrack, to be used only for testing purposes (not part of normal simulation workflows)
• Tracker(... sequence= ... ) becomes Tracker(... line= ... )

New feature

• Tracker class has new methods for closed-orbit search and one-turn-matrix calculation with finite differences

Xtrack version 0.3.3

New feature:

• Aperture interpolation now works in the presence of thick and collective elements

Interface modification:

• Isolated elements do not update at_element and at_turn, which are instead handled only by the Tracker objects
