field100 module

Define the rf field corresponding to FIELD_MAP 100.

This is 1D longitudinal field along z. The only one that is completely implemented for now.

class Field100(field_map_path: Path, length_m: float, z_0: float = 0.0)

Define a RF field, 1D longitudinal.

_load_fieldmap(path: Path, **validity_check_kwargs) → tuple[Callable[[float], float], tuple[int], int]

Load a 1D field (.edz extension).

Parameters:

path (pathlib.Path) – The path to the .edz file to load.

Returns:

e_z (Callable[[Pos1D], float]) – Function that takes in z position and returns corresponding field, at null phase, for amplitude of \(1\,\mathrm{MV/m}\).
n_z (tuple[int]) – Number of interpolation points.
n_cell (int) – Number of cell for cavities.

shift() → None: Shift the electric field map.

Warning

You must ensure that for z < 0 and z > element.length_m the electric field is null. Interpolation can lead to funny results!

e_z(pos: float, phi: float, amplitude: float, phi_0_rel: float) → complex: Give longitudinal electric field value.
