# The `ISIS_IMAT` Instrument

## Identification

- Site: ISIS
- Author: Genoveva Burca (Genoveva.Burca@stfc.ac.uk)
- Origin: ISIS
- Date: October 2017

## Description

    McStas instrument for simulating the IMAT - imaging and diffraction
    New McStas moderator file (G. Skoro, ISIS Facility) was added
    \\ISIS\Shares\NeutronicsTeam\TS-2\HydroMod_Upgrade\McStas_TS2_HydroMod_Base_newVirtMod_350mm\Let_Base.mcstas
    Components positions were extracted from IMAT final design (March 2016)
    Choppers were not added to this model
    Diffraction detectors are
