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		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
