McXtrace: DivE_monitor Component

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

The DivE_monitor Component

Based on neutron component by Kristian Nielsen Divergence/Energy monitor.

Identification

  • Author: Erik B Knudsen
  • Origin: DTU Physics
  • Date: Jun. 2016
  • Version: $Revision$

Description

2D detector for intensity as a function of both horizontal divergence
and Energy.

Example: DivE_monitor(nE=20, nh=20, filename="Output.div",
          xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,
          maxdiv_h=2, Emin=2, Emax=10)

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
nE 1 Number of bins in energy 20
nh 1 Number of bins in divergence 20
filename string Name of file in which to store the detector image 0
xmin m Lower x bound of detector opening -0.05
xmax m Upper x bound of detector opening 0.05
ymin m Lower y bound of detector opening -0.05
ymax m Upper y bound of detector opening 0.05
xwidth m Width of detector. Overrides xmin,xmax. 0
yheight m Height of detector. Overrides ymin,ymax. 0
maxdiv_h degrees Maximal horizontal divergence detected 2
Emin keV Minimum energy detected  
Emax keV Maximum energy detected  
restore_xray 1 If set, the monitor does not influence the photon state 0
nx 0
ny 1 Vector definition of "forward" direction wrt. divergence, to be used e.g. when the monitor is rotated into the horizontal plane. 0
nz 1
nowritefile 1 If set, monitor will skip writing to disk. 0

Output parameters

Name Unit Description Default
Div_N - Array of photon ray counts  
Div_p - Array of photon weight counts  
Div_p2 - Array of second moments
