core.beam_parameters.phase_space.initial_phase_space_beam_parameters module

Handle the initial beam parameters of a single phase space.

For a list of the units associated with every parameter, see Units and conventions.

Note

In this module, angles are stored in deg, not in rad!

class InitialPhaseSpaceBeamParameters(phase_space_name: str, eps_no_normalisation: float, eps_normalized: float, envelopes: ndarray | None = None, twiss: ndarray | None = None, sigma: ndarray | None = None, tm_cumul: ndarray | None = None, mismatch_factor: float | None = None)

Bases: IPhaseSpaceBeamParameters

Hold Twiss, emittance, envelopes of single phase-space @ single pos.

__post_init__() → None: Ensure that the phase space exists.
