McStas: Test_FocalisationMirrors

[ Identification | Description | Input parameters | Links ]

The Test_FocalisationMirrors Instrument

Test instrument for neutron focalisation with a set of supermirrors. No guide / velocity selector One parabolic SM converges the incoming beam to its focal point, then one elliptic SM (with primary focal point at same location as parabolic SM focal point) images the focal point onto the detector.
