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

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			6.66
DLAMBDA			0.1
GUIDEREFLECTIVITY			1.0
