* McXtrace instrument definition URL=http://www.mcxtrace.org
*
* Instrument: Test_Saxs_spheres
*
* %Identification
* Written by: Your name (email)
* Date: Current Date
* Origin: Your institution
* Release: McXtrace 1.0
* Version: 0.2
* %INSTRUMENT_SITE: Tests_samples
*
* Test instrument for the Saxs_spheres sample component.
*
* Simply a model source illuminating a Saxs_spheres sample.
* The spheres are nominally made from Be in non-absorbing solution.
*
* %Example: Test_Saxs_spheres.instr -n1e6 RR=20 Detector: detector2_I=5.0956e-16
*
* %Parameters
* RR: [AA] Radius of the dilute hard spheres.
*
