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, length_m, z_0=0.0)

Bases: Field

Define a RF field, 1D longitudinal.

Parameters:

• field_map_path (Path)

• length_m (float)

• z_0 (float, default: 0.0)

extensions: Collection[str] = ('.edz',)

is_implemented: bool = True

_load_fieldmap(path, **validity_check_kwargs)

Load a 1D field (EDZ extension).

Parameters:

path (Path) – The path to the EDZ file to load.

Return type:

tuple[Callable[[float], float], tuple[int], int]

Returns:

• e_z – Function that takes in z position and returns corresponding field, at null phase, for amplitude of \(1\,\mathrm{MV/m}\).

• n_z – Number of interpolation points.

• n_cell – Number of cell for cavities.

shift()

Shift the electric field map. :rtype: None

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, phi, amplitude, phi_0_rel)

Give longitudinal electric field value.

Parameters:

• pos (float)

• phi (float)

• amplitude (float)

• phi_0_rel (float)

Return type:

complex
