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, eps_no_normalization, eps_normalized, envelopes=None, twiss=None, sigma=None, tm_cumul=None, mismatch_factor=None)[source]

Bases: IPhaseSpaceBeamParameters

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

Parameters:
eps_no_normalization: float
eps_normalized: float
mismatch_factor: float | None = None
__post_init__()[source]

Ensure that the phase space exists.

Return type:

None

classmethod from_sigma(phase_space_name, sigma, gamma_kin, beta_kin, beam_kwargs, **kwargs)[source]

Compute Twiss, eps, envelopes just from sigma matrix.

Parameters:
Return type:

Self
