pysrw.computations.computeSpectrum(particleBeam, magnetsContainer, observer, fromWavelength=None, toWavelength=None, numPoints=None, relPrec=None, srApprox=None)[source]#

Compute the spectrum of synchrotron radiation emitted by a particle travelling along a magnetic structure.

Parameters:

  • particleBeam – particle instance of ParticleBeam.

  • magnetsContainer – container instance of MagnetsContainer.

  • observer – mesh instance of Observer. Check WavefrontMultiWavelength for further details about the observer definition.

  • fromWavelength – lower wavelength in nanometers.

  • toWavelength – upper wavelength in nanometers.

  • numPoints – number of wavelengths to simulate.

  • relPrec (optional) – relative precision target for the convergence of the computation. If None, the default value set in CONFIG is used. Defaults to None.

  • calcMeth (optional) – one of the configuration.SR_APPROX approximation methods to use for the computation. If None, the default value set in CONFIG is used. Defaults to None.

Returns:

the calculated field spectral distribution.

Return type:

WavefrontMultiWavelength
