McXtrace: Phi_monitor Component

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

The Phi_monitor Component

Phase-sensitive monitor.


  • Author: Erik B Knudsen
  • Origin: DTU Physics
  • Date: June, 2019
  • Version: $Revision$


A square single monitor that measures the phase of the incoming x-rays. The phase is measured
mod 2*pi in the range 0 to 2*pi.

Example: Phi_monitor(xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1,nPhi=20, filename="Output.dat")

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
nPhi 1 Number of phase bins 20
filename 1 Name of file in which to store the data 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
Phimin 1 Minimum phase to detect. 0
Phimax 1 Maximum phase to detect 2*M_PI
restore_xray 1 If set, the monitor does not influence the xray state 0
nowritefile 1 If set, monitor will skip writing to disk 0

Output parameters

Name Unit Description Default
Phi_N - Array of x.ray counts  
Phi_p - Array of x-ray weight counts  
Phi_p2 - Array of second moments
