The SANSQMonitor McStas Component

A circular detector measuring the radial average of intensity as a function of the momentum transform in the sample.

A simple component simulating the scattering from a box-shaped, thin solution of monodisperse, spherical particles.

Parameters in boldface are required; the others are optional.


Name	Unit	Description	Default



NumberOfBins		Number of bins in the r (and q).	100
RFilename		File used for storing I(r).	"RDetector"
qFilename		File used for storing I(q).	"QDetector"
RadiusDetector	m	Radius of the detector (in the xy-plane).
DistanceFromSample	m	Distance from the sample to this component.
LambdaMin	Å	Max sensitivity in lambda - used to compute the highest possible value of momentum transfer, q.	1.0
Lambda0	Å	If lambda is given, the momentum transfers of all rays are computed from this value. Otherwise, instrumental eﬀects are neglected.	0.0
restore_neutron		If set to 1, the component restores the original neutron.	0
