The Tools_ONION Instrument

Instrument short description:

Identification

  • Site:
  • Author: Thomas Huegle
  • Origin: ORNL
  • Date: July 2019
  • Version:(Unknown)

Description

Test case for an layered detector shell instrument to provide quick overview of resolution per pixel.
Set up to be run in McStas -> Mantid mode, refer to manual for details on execution.
Simulates desired divergence by adjusting moderator size.
Considers only in-plane (xwidth) factors, sets yheight as 1 cm.
For an example on how to analyze the data, see the 'Onion_analyzerScript.py' available at 
https://github.com/McStasMcXtrace/McCode-contribution-support-docs/tree/master/McStas/2.6_Onion_tool_T_Huegle

Acceptable statistics can be achieved by running the simulation with 1E7 neutrons (output file: ~400MB) 


Input parameters

Parameters in boldface are required; the others are optional.
Name Unit Description Default
divergence degrees angular divergence of neutrons reaching the sample 0.4
distance m distance between source and sample 32
