[SasView Users] Core + 2 shells cylinder model

[richard.heenan at stfc.ac.uk]

Dear Irena,

 

PS  For the specific case of carbon nanotubes, the cylinders are of course 
very long and thin, so writing a model that performs the necessary numerical
  integrations reliably and accurately is non-trivial. Some other members of
 the sasview coding team have already had some thoughts in this direction .

Dear Irena,

 

As you have noticed, SasView does not have a multi-shell cylinder model. Bu
t since you are now the third person in the last  6 months to have asked for
 such a model, maybe it is about time we provided one! I will ‘ticket’ t
he requirement…

 

In the meantime, the only fitting program I know with such a model is Olivi
er Tache’s pySAXS. But it is not the most straightforward  program to use.

 

Kind regards,

Steve King

Hello,

I'm a PhD student in the chemical engineering dept. at the Technion institu
te of technology, Israel.

I study carbon nanotubes dispersions stabilized with dispersants using SANS
.

 

I am looking for a model similar to the idea of "core_multi_shell" but for 
a cylinder instead of  a sphere. I need a cylinder with a core and 2 concent
ric shells,  each shell has its own SLD.

 

Are you familiar with such a model?

I've looked in the search engine and in the marketplace but could not find 
such a model.

 

Best,

Irena Levin
