McStas: SANSNanodiscsWithTagsFast Component

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

The SANSNanodiscsWithTagsFast Component

A sample of monodisperse phospholipid bilayer nanodiscs in solution (water) - with histidine tag still on the belt proteins.

Identification

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

Description

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

WARNING: This is a contributed Component.
