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

Bases: Task

Compute a bending-magnet (BM) spectrum using XOPPY’s xoppy_calc_bm.

Inputs (units):

• TYPE_CALC (int): must be 0.

• VER_DIV (int): vertical divergence model, {0, 2}.

• MACHINE_NAME (str), RB_CHOICE (int), MACHINE_R_M (m).

• BFIELD_T (T), BEAM_ENERGY_GEV (GeV), CURRENT_A (A), HOR_DIV_MRAD (mrad).

• PHOT_ENERGY_MIN / PHOT_ENERGY_MAX (eV), NPOINTS (int), LOG_CHOICE (0/1).

• PSI_* (mrad) and PSI_NPOINTS (int), FILE_DUMP (bool).

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])
