The SANS_benchmark2 Component

Identification

Description

Example: SANS_benchmark(xwidth=0.01, yheight=0.01, zthick=0.001, model=1.0, dsdw_inc=0.02, sc_aim=0.97, sans_aim=0.95, singlesp = 0.0)

Input parameters

Parameters in boldface are required; the others are optional.
NameUnitDescriptionDefault
xwidthmwidth of sample volume0.01
yheightmheight of sample volume0.01
zthickmthickness of sample volume0.001
modelmodel no., real variable will be rounded. negative numbers interpreted as model #0, too large as #18.1.0
dsdw_incthe incoherent background from the overall sample (cm-1), should read ca. 1.0 for water, 0.5 for half D2O, half H2O, and ca. 0.02 for D2O0.02
sc_aimthe fraction of neutron paths used to represent the scattered neutrons (including everything: incoherent and coherent). rest is transmission.0.97
sans_aimthe fraction of neutron paths used to represent the scattered neutrons in the sans-range (up to 1.0AA-1). rest is incoherent with Q>1AA-1.0.95
singlespswitches between multiple scattering (parameter zero 0.0) and single scattering (parameter 1.0). The sc_aim directs a fraction of paths to the first scattering process accordingly. The no. of paths for the second scattering process is derived from the real probability. Up to 10 scattering processes are considered.0.0
