[ Identification | Description | Input parameters | Output parameters | Links ]

The Bending_magnet Component

Release: McXtrace 1.2 Model of a bending magnet source

Identification

  • Site:
  • Author: Erik B. Knudsen
  • Origin: DTU Physics
  • Date: May, 2013.

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.
NameUnitDescriptionDefault
E0keVCenter of emitted energy spectrum (overrides lambda0)0
dEkeVHalf-width of emitted energy spectrum0
lambda0AACenter of emitted wavelength spectrum0
dlambdaAAHalf-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
EeGeVStorage ring electron energy (typically a few GeV)2.4
IeARing current0.4
tbunchsBunch length. 0 means continous source.0
t0sDelay of the first bunch from t=00
BTMagnet field strength1.6
sigey Electron ring beam size in vertical plane (rms)0
sigex Electron ring beam size in horizontal plane (rms)0
focus_xwmWidth of target window0
focus_yh0
distmDistance from source plane to target window along the optical axis1
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
