class ewokstomo.tasks.energycalculation.ComputeWigglerSpectrum(inputs=None, varinfo=None, node_id=None, node_attrs=None, execinfo=None, profile_directory=None)

Bases: Task

Compute a wiggler spectrum on an aperture using xoppy_calc_wiggler_on_aperture.

Inputs (units):

• PHOT_ENERGY_MIN / PHOT_ENERGY_MAX (eV), NPOINTS (int).

• ENERGY (GeV), CURRENT (mA).

• FIELD, NPERIODS (int), ULAMBDA (m), K (–), NTRAJPOINTS (int), FILE (str).

• SLIT_*: distances in m/mm per name; flags as ints.

• SHIFT_X_VALUE (m), SHIFT_BETAX_VALUE (rad).

• TRAJ_RESAMPLING_FACTOR, SLIT_POINTS_FACTOR (floats), LOG_CHOICE (0/1).

Outputs:

• energy_eV (eV), sorted ascending.

• flux (phot/s/0.1%bw) as returned by XOPPY.

• spectral_power (W/eV).

• cumulated_power (W).

Parameters:

• inputs (Optional[Mapping])

• varinfo (Optional[dict])

• node_id (Union[str, int, tuple, None])

• node_attrs (Optional[dict])

• execinfo (Optional[dict])

• profile_directory (Optional[dict])
