/*******************************************************************************
* McXtrace instrument definition URL=http://www.mcxtrace.org
*
* Instrument: Simple_1shell
*
* %Identification
* Written by: Erik B Knudsen <erkn@fysik.dtu.dk> & Desiree D. M. Ferreira <desiree@space.dtu.dk> (email)
* Date: 12/12/2016
* Origin: DTU Physics/DTU Space
* Release: McXtrace 1.2
* Version: 1.0
* %INSTRUMENT_SITE: AstroX_ESA
*
* Single shell model of a true Wolter Type I optic
*
* %Description
* Single shell example telescope using a combinatiopn pf parabolic/hyperbolic shell
* optical plates covering the full circle. Reflectivity is 1 for all energies.
*
* Example: Simple_1shell.instr FL=12
*
* %Parameters
* FL: [m] The focal length of the optical system
* plate_zdepth: [m] Plate length.
* channel_yheight: [m] Channel height.
* radius_p: [m] Radius at the entry to the primary (parabolic) shell.
* radius_m: [m] Radius at the optics centre.
* radius_h: [m] Radius at the exit of the secondary (hyperbolic) shell.
*
* %End
