Description
A circular detector measuring the radial average of intensity as a function of the momentum transform in the sample. The q-range is set up to qMax = 4 * PI * sin(TwoThetaMax / 2.0) / LambdaMin;
Example: SAXSQMonitor( RadiusDetector = 0.1, DistanceFromSample = 0.5, LambdaMin = 1, Lambda0 = 1.54, NumberOfBins = 2000 ) Example: SAXSQMonitor( RadiusDetector = 0.1, qMax = 5, Lambda0 = 1.54, NumberOfBins = 2000 )
