- class apace.tracking_matrix.TrackingMatrix(lattice, initial_distribution, turns=1, watch_points=None, start_point=0, **kwargs)¶
Inherits:
apace.matrixmethod.MatrixMethodParticle tracking using the transfer matrix method.
- Parameters
lattice (Lattice) – Lattice which particles will be tracked through.
initial_distribution (np.ndarray) – Initial particle distribution.
turns (int) – Number of turns.
watch_points (array-like, optional) – List of watch points. If unset all particle trajectory will be saved for all positions. Indices correspont to
orbit_positions.start_point (int) – Point at which the particle tracking begins.
