McStas: SANSNanodiscsFast

[ Identification | Description | Input parameters | Links ]

The SANSNanodiscsFast Component

A sample of monodisperse phospholipid bilayer nanodiscs in solution (water).

Identification

  • Site:
  • Author: Martin Cramer Pedersen (mcpe@nbi.dk)
  • Origin: KU-Science
  • Date: October 17, 2012

Description

A component very similar to EmptyNanodiscs.comp - however, the scattering
profile is only computed once, and linear interpolation is the used to
simulate the instrument.

Input parameters

Parameters in boldface are required; the others are optional.
