class pysrw.lib.srwlib.SRWLMagFldH(_n=1, _h_or_v='v', _B=0, _ph=0, _s=1, _a=1)[source]#

Magnetic Field: Undulator Harmonic

__init__(_n=1, _h_or_v='v', _B=0, _ph=0, _s=1, _a=1)[source]#

Parameters:

_n – harmonic number
_h_or_v – magnetic field plane horzontal (‘h’) or vertical (‘v’)
_B – magnetic field amplitude [T]
_ph – initial phase [rad]
_s – symmetry vs longitudinal position 1 - symmetric (B ~ cos(2*Pi*n*z/per + ph)) , -1 - anti-symmetric (B ~ sin(2*Pi*n*z/per + ph))
_a – coefficient for transverse depenednce B*cosh(2*Pi*n*a*y/per)*cos(2*Pi*n*z/per + ph)

Methods
