McStas: StatisticalChopper_Monitor Component

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

The StatisticalChopper_Monitor Component

Monitor designed to compute the autocorrelation signal for the Statistical Chopper


  • Author: C. Monzat/E. Farhi
  • Origin: ILL
  • Date: 2009
  • Version:(Unknown)


This component is a time sensitive monitor which calculates the cross 
correlation between the pseudo random sequence of a statistical chopper 
and the signal received. It mainly uses fonctions of component Monitor_nD.
It is possible to use the various options of the Monitor_nD but the user MUST NOT
specify "time" in the options. Auto detection of the time limits is possible if the 
user chooses tmin=>tmax.

StatisticalChopper_Monitor(options ="banana bins=500, abs theta limits=[5,105],bins=1000")

WARNING: This is a contributed Component.

Input parameters

Parameters in boldface are required; the others are optional.
