# The `Test_shellguides` Instrument

This is an instrument test file for 3 components.

## Identification

- Site: tests
- Author: Tobias Panzner, Uwe Filges
- Origin: PSI
- Date: 10.07.2010
- Version: 0.2

## Description

    In the instrument files 3 new components are used:

     - Sapphire_Filter.comp   : models a sapphire filter for suppression of a unwanted high energy part of a given source spectrum
                                (the properties can be changed in the instrument file itself)

     - Guide_four_side.comp   : models a guide with different wall properties. here it is only a ordinary linear guide with reflecting walls.
                                (the properties can be changed in the instrument file itself)

     - Guide_four_side_10_shells.comp: models a multi channel component. here it is used as a parabolic focusing lens (default values).
                                       some of the parameters can be change in the mcgui start menu to play around with the focusing properties.

    Example: mcrun test.instr <parameters=values>

## Input parameters

Parameters in boldface are required; the others are optional.
