srxraylib.sources.srfunc

srfunc: calculates synchrotron radiation emission (radiation and angle distributions).

functions:

basic:

• fintk53: integral of the Bessel function K5/3(x).

• sync_g1: energy spectrum integrated over the full vertical angle.

• sync_f: angular dependence of synchrotron radiation.

• sync_hi: function Hi(x) = x^i * BeselK(x/2,2/3).

bending magnet radiation:

• sync_ang: angular distributions.

• sync_ene: energy distributions.

wiggler radiation:

• wiggler_trajectory: computes the electron trajectroy in a magnetic field (sinusoidal or from a file with B[T] or its harmonic decomposition).

• wiggler_spectrum: computes the wiggler spectrum (full emission) given the trajectory.

• wiggler_nphoton: computes the number of photons emtted versus bending radius per (1mA 1mrad (horizontal) 0.1% bandwidth).

• wiggler_harmonics: computes the harmonic decomposition of the magnetic field B(s).

• wiggler_cdf: computes the cumulative distribution function from radiation.
