Model of a wiggler source

Identification

A source model based on the derivation from B.D. Patterson, Am. J. Phys. 79, 1046 (2011); doi: 10.1119/1.3614033

Parameters in boldface are required; the others are optional.

Name	Unit	Description	Default
verbose		if nonzero, output extra information	0
E0	keV	Center of emitted energy spectrum (overrides lambda0)	0
dE	keV	Half-width of emitted energy spectrum	0
lambda0	AA	Center of emitted wavelength spectrum	0
dlambda	AA	Half-width of emitted wavelength spectrum	-1
phase		Initial phase of radiation.	0
randomphase		If !=0 phase will be random (I.e. the emitted radiation is completely incoherent)	1
Ee	GeV	Storage ring electron energy (typically a few GeV)	2.4
Ie	A	Ring current	0.4
tbunch	s	Bunch length. 0 means continous source.	0
t0	s	Delay of the first bunch from t=0	0
B	T	Peak magnet field strength	1.6
K		Dimensionless undulator parameter. overrides B.	3
gap	m	Wiggler gap.	1e-3
Nper		Number of magnetic periods in the wiggler	1
length	m	Length of the Wiggler.	1
sigey		Electron ring beam size in vertical plane (rms)	0
sigex		Electron ring beam size in horizontal plane (rms)	0
focus_xw	m	Width of target window	0
focus_yh	m	Height of target window	0
dist	m	Distance from source plane to target window along the optical axis	1
gauss_t		if 0 the target window will be sampled uniformly and the weight adjusted accordingly, otherwise we will use a gaussian sampling scheme.	0
