McStas: ISIS_OSIRIS Instrument at ISIS

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

The ISIS_OSIRIS Instrument

A simulation of the indirect TOF geometry part of the OSIRIS instrument.

Identification

  • Site: ISIS
  • Author: Peter Christiansen with input from Mark Telling, updates by P Willendrup
  • Origin: DTU Fysik, RISOE and ISIS
  • Date: November 2015
  • Version:

Description


If LAMBDA = 0, the choppers are disabled, else the choppers are
centered to chop around this wavelength and the source is studied in the 
interval LAMBDA +- DLAMBDA.

IMPORTANT NOTES:

1) Monchromator is not realistic in the sense that it does NOT
   smear the beam out according to the mosaicity, only does the N=1 
   reflection, and the d-spread is handled in a simple way

2) The instrument is not validated or certified by ISIS. Is only put in
   McStas for completeness.

Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
LAMBDA AA Central wavelength of source and chopper wavelength 6.66
DLAMBDA AA Source interval [LAMBDA-DLAMBDA; LAMBDA+DLAMBDA] 0.1
GUIDEREFLECTIVITY 1 Max reflectivity of guide 1.0
