Wiggler ComponentA source model based on the derivation from B.D. Patterson, Am. J. Phys. 79, 1046 (2011); doi: 10.1119/1.3614033 Example: Wiggler( E0 = 14, dE = 12, Ee = 2.75, Ie = 0.5, B = 2.1, K=10, Nper=41, sigey=9.3e-6, sigex=215.7e-6)
| Name | Unit | Description | Default | |
| 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 | 0 | |
| phase | rad | Initial phase of radiation. | 0 | |
| randomphase | 0/1 | 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 | |
| B | TT] Peak magnet field strength | 1.6 | ||
| K | 1 | Dimensionless undulator parameter, e.g. K >> 1. overrides B. | 3 | |
| Nper | int | Number of magnetic periods in the wiggler | 1 | |
| length | m | Length of the Wiggler. | 1 | |
| sigey | m | Electron ring beam size in vertical plane (rms) | 0 | |
| sigex | m | Electron ring beam size in horizontal plane (rms) | 0 | |
| focus_xw | m | Width of target window | 0 | |

| dist | m | Distance from source plane to target window along the optical axis | 1 | |
| gauss_t | 0/1 | If 0 the target window will be sampled uniformly and the weight adjusted accordingly, otherwise we will use a gaussian sampling scheme. | 0 | |
| verbose | 0/1 | If nonzero, output extra information | 0 | |
