The Wiggler Component

Model of a wiggler source

Identification

Description

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

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
verbose if nonzero, output extra information 0
E0 overrides lambda0 [keV] Center of emitted energy spectrum 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 I.e. the emitted radiation is completely incoherent [ ] If !=0 phase will be random 1
Ee typically a few GeV [GeV] Storage ring electron energy 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 rms [ ] Electron ring beam size in vertical plane 0
sigex rms [ ] Electron ring beam size in horizontal plane 0
focus_xw m Width of target window 0
focus_yh 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
