McStas: SANSLiposomes Component

[ Identification | Description | Input parameters | Output parameters | Links ]

The SANSLiposomes Component

A sample of polydisperse liposomes in solution (water).

Identification

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

Description

A component simulating the scattering from a box-shaped, thin solution (water)
of liposomes described by a pentuple-shell model.

WARNING: This is a contributed Component.
