• Multipolar components (knl and ksl) available in Bend, Quadrupole, Sextupole, Octupole.

Full Changelog: v0.58.0...v0.59.0

Xtrack version 0.58.0

Changes:

• Move kernel prebuilding to the xsuite package by @szymonlopaciuk in #483

Full Changelog: v0.57.3...v0.58.0

Xtrack version 0.57.3

Changes:

• Fix in loss location refinement (build of auxiliary track kernel)

Full Changelog: v0.57.2...v0.57.3

Xtrack version 0.57.2

Changes:

• Introduce Line.get_ibs_growth_rates(...)
• Introduce Line._insert_thick_elements_at_s(...)
• Replace _allow_backtrack with _allow_loss_refinement
• Add s_tol in element insertion methods.
• Better initialization of io_buffer

Full Changelog: v0.57.1...v0.57.2

Xtrack version 0.57.1

Changes:

• Introduce new particles properties: kin_px, kin_py, kin_ps, kin_xprime, kin_yprime.
• Adapt tests (to avoid issue of cpymad)

Xtrack version 0.57.0

Changes:

• Introduce more compact json format (parameters equal to defaults are not stored)
• Slicing done with slice-elements referring to the parent. Parent element can be updated also after the slicing and slice elements are updated accordingly. As a result no expression is generated when slicing an element.
• Introduced Replica class to have multiple instances of the same element.
• Element lengths and magnet strengths correctly extracted for replicas and slices in Line.attr, Line.get_table() and Line.twiss().
• Introduced shift_x, shift_y and rot_s_rad properties to all elements in order to introduce misalignments.
• Introduced aperture associated to an element. If present, this is taken into account when slicing the element.
• TwissTable.reverse() reverses also the magnet strengths.
• More efficient and general survey (vertical bends are correctly handled).
• Rationalize element insertion (uses slicing capabilities).
• Removed only_markers flag in twiss.
• Removed element compounds (superseded by capabilities described above).

• Add TargetRmatrix for the matching of R-matrix terms over a section of a beam line.
• Add search_for_trev mode in twiss.
• Handle bv flag in MAD-X loader.
• Switch to exact drift as fallback in solenoid with zero strength.

Full Changelog: v0.54.2...v0.55.0
