Description

This instrument is a model of the FOCUS Spectrometer at PSI, Villigen, CH.

input parameters :
   lambda      : source energy                               [Angs]
   chopp_ratio : chopper radio Fermi Chopper to Disk Chopper [1]
   DET         : Detector angle                              [deg]
