Input parameters

Parameters in boldface are required; the others are optional.
NameUnitDescriptionDefault
pinhole_radmradius of the collimating pinholes. Also used to optimise the sample size.0.004
LCmlength of the collimator - distance between pinholes3
LDmdistance between the last pinhole slit and detector3
LambdaAngsAverage wavelength traced from source6
DLambdaAngsWavelength band +/- traced from source0.001
Rmaverage radius of the monodisperse spheres in the sample400
dRAANormal variance of the radius of spheres in the sample. If zero the sample is monodisperse.0
PHI1Volumefraction of the hard spheres in the sample1e-2
Delta_Rhofm/Angs^3Volume specific scattering length density contrast of the hard, monodisperse spheres in the sample as compared to the solution0.6
BEAMSTOP0/1If set, the beamstop is inserted in front of the detector in order to block the transmitted beam1
SAMPLE0/1If set, a sample of spheres or spherical shells is inserted1
